The primary sex organs are the gonads, a pair of sex organs, specifically the testes in the male or the ovaries in the female. As primary sex organs, gonads generate reproductive gametes containing inheritable DNA. They also produce most of the primary hormones that affect sexual development, and regulate other sexual organs and sexually differentiated behaviors. Secondary sex organs refer the rest of the reproductive system, whether internal or external.
|
|
All others are called secondary sex organs, divided between the external sex organs—the genitals or genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen.

Physical sex characteristics include primary sex characteristics and secondary sex characteristics. A primary sexual characteristic, as narrowly defined, is any anatomical part of the body involved in sexual reproduction and constituting the reproductive system in a complex organism, especially the external sex organs; the external sex organs are also commonly referred to as the genitalia or genitals. Secondary sex characteristics are features that appear at sexual maturity in animals and during puberty in humans, especially the sexually dimorphic phenotypic traits that distinguish the sexes of a species, but that, unlike the sex organs, are not directly part of the reproductive system.

There are three extant kinds of mammals: monotremes, placentals and marsupials, all with internal fertilization. In placental mammals, offspring are born as juveniles: complete animals with the sex organs present although not reproductively functional. After several months or years, depending on the species, the sex organs develop further to maturity and the animal becomes sexually mature. Most female mammals are only fertile during certain periods during their estrous cycle, at which point they are ready to mate.

In this case, testosterone is not made and the Wolffian duct will degrade thus, the Müllerian duct will develop into female sex organs. The clitoris is the remnants of the Wolffian duct. On the other hand, if the fetus inherits the Y chromosome from the father, the fetus will be a male. The presence of testosterone will stimulate the Wolffian duct which will bring about the development of the male sex organs and the Müllerian duct will degrade.

In other cases, the external sex organs have an appearance that would be expected to be seen with the "opposite" gonadal tissue. Because of this, pseudohermaphroditism is sometimes not identified until puberty or adulthood. Associated conditions include 5-α-reductase deficiency5ARD is also known as 5-α-reductase 2 deficiency because the 5-α-reductase 2 gene is deficient and androgen insensitivity syndrome.

The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum (zygote) develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.

Aplysia vaccaria is a simultaneous hermaphrodite. Simultaneous hermaphrodites are organisms that have both male and female sex organs that are able to contribute to sexual reproduction at the same time, which is distinct from non-simultaneous hermaphrodites which only have one sex organ present or functional at any one point in time. Being simultaneously hermaphroditic is advantageous because any two individuals are able to reproduce with one another, which facilitates Aplysia vaccaria finding a mate. However, despite having both sex organs functional during reproduction, only one Aplysia vaccaria acts as a sperm donor during the mating encounter.

The goal of early transition surgeries was the removal of hormone-producing organs (such as the testicles and the ovaries) in order to reduce their masculinizing or feminizing effects. Later, as surgical technique became more complex, the goal became to produce functional sex organs from sex organs that are already present in the patient. In the US in 1917, Dr. Alan L. Hart, an American tuberculosis specialist, became one of the first female-to-male transsexuals to undergo hysterectomy and gonadectomy for the relief of gender dysphoria. In Berlin in 1931, Dora Richter, became the first known transgender woman to undergo the vaginoplasty surgical approach.

No major pathological changes are observed in Rhipicephalus appendiculatus ticks infected with THOV. The virus is concentrated in the synganglion (the tick brain) early on in the blood-feeding process, with the proportion of virus located in the salivary glands increasing during the late phase of blood-feeding. Lower levels of virus are found in the trachea, digestive tract and female sex organs, but not in the male sex organs or the excretory system. The high level of virus present in the synganglion has been proposed to help the virus persist through the metamorphosis of the tick, as the nervous system undergoes less remodeling than other systems.

The life cycle of land plants involves alternation of generations between a sporophyte and a haploid gametophyte. The gametophyte produces sperm or egg cells by mitosis. The sporophyte produces spores by meiosis which in turn develop into gametophytes. Any sex organs that are produced by the plant will develop on the gametophyte.

In 1711, R.A.F de Réaumur gave an account of Fucus in which noted the two types of external openings in the thallus: the non-sexual cryptostromata (sterile surface cavities) and the conceptacles (fertile cavities, immersed but with a surface opening) containing the sexual organs, which he thought were female flowers. With a lens he was able to see the oogonoa (the female sex organs) and the antheridia (the male sex organs) within the conceptacles, but he interpreted these as seeds (Morton, 1981 p. 245). Johann Hedwig (1730–1799) provided further evidence of the sexual process in algae, and figured conjugation in Spirogyra Hedwig in 1797. He also illustrated Chara (Charales) and identified the antheridia and oogonia as male and female sexual organs (Morton, 1981 p.

Reconstruction of the male (with head clasper) and female Ctenurella had a long, whip-like tail, large eyes, and robust upper and lower jaw tooth plates. Males also had hook-shaped sex organs, known as claspers. Since analogous features are also found in the unrelated living chimaeras, chimaeras and ptyctodonts are thought to be an example of convergent evolution.

A human fetus does not develop its external sexual organs until seven weeks after fertilization. The fetus appears to be sexually indifferent, looking neither like a male or a female. Over the next five weeks, the fetus begins producing hormones that cause its sex organs to grow into either male or female organs. This process is called sexual differentiation.

Members of the tribe are palms with fan shaped (or palmate) leaves and are pleonanthic—they flower repeatedly over the course of their lifespan. They are usually hermaphroditic (male and female sex organs are present together in flowers), but some species are polygamodioecious, in which some plants have both male and hermaphroditic flowers, while others have a mixture of female and hermaphroditic flowers.

Sexual dimorphism is where the basic phenotypic traits vary between males and females of the same species. Dimorphism is found in both sex organs and in secondary sex characteristics, body size, physical strength and morphology, biological ornamentation, behavior and other bodily traits. However, sexual selection is only implied over an extended period of time leading to sexual dimorphism.Dimijian, G. G. (2005).

The booklet not only offered information to soldiers about avoiding V.D., but also what to do if they became infected. The pamphlet provided sufficient information about various diseases to allow troops to diagnose diseases and infections without visiting the Pro-Station. The following is the Summary which is offered by the pamphlet: :1. Manhood comes from healthy sex organs. :2.

Individual statues of young women also show them kneeling, but with additional characteristics such as visible sex organs, which are not visible on the paired statues. This female figure is thought to represent a fertility or Earth Mother goddess. The birdman, hand in eye, solar cross, and other symbols associated with the Southeastern Ceremonial Complex appear in many artifacts found at Etowah.

Ptychostomella sp., Macrodasyida Gastrotrich reproduction and reproductive behaviour has been little studied. That of macrodasiyds probably most represents that of the ancestral lineage and these more primitive gastrotrichs are simultaneous hermaphrodites, possessing both male and female sex organs. There is generally a single pair of gonads, the anterior portion of which contains sperm-producing cells and the posterior portion producing ova.

This led researchers to question what other effects this has on mammals. It showed that BPA leads to meiotic changes such as fertility and maturation of sex organs. Scientists started to realize that this type of exposure could lead to mutations and affect multiple generations. Because of this, "BPA free" products started to be made but to do this, BPS was being used.

In Aboriginal mythology (specifically: Karadjeri), the Bagadjimbiri are two brothers and creator gods. They arose from the ground as dingos and made water-holes, sex organs (from a mushroom and another fungus) for the androgynous first people, and invented circumcision. Taking human form, the Bagadjimbiri began an argument with Ngariman, a cat-person. Ngariman was annoyed by the Bagadjimbiri's laughter.

Erik Schinegger, the 1966 female downhill world champion from Austria, was tested a couple of days before the 1968 Winter Games; it turned out she was actually a man. Schinegger, whose gender had not been correctly identified for years because she had internal male sex organs, decided to have the operation and changed her first name from Erika to Erik.

In 1777, the Italian Carlo Mondini located an eel's ovaries and demonstrated that eels are a kind of fish. In 1876, as a young student in Austria, Sigmund Freud dissected hundreds of eels in search of the male sex organs. He had to concede failure in his first major published research paper, and turned to other issues in frustration. Vol. 75, p. 419.

Both went on to become Playmate of the Year, respectively 1972 and 1973. When Hustler was launched in 1974, it outdid both Playboy and Penthouse in explicitness by showing more graphic photos of the female sex organs. Eventually, the two magazines moved their content in opposite directions. Playboy positioned itself as the less explicit softcore alternative to be "read for the articles".

Its intestine is six-times longer than its body and the caecum is twice the volume of its stomach. The fecal matter of the beaver takes the form of balls of sawdust which it deposits into the water. The sex organs of a beaver are located within the body. Beavers have one opening, a cloaca, that contains the genital, digestive and excretory openings.

Hyraxes have upper tusk-like upper incisors and four lower incisors that are comb-like and used to groom the fur. While the incisors do not differentiate between the hyraxes, they do differ between sexes. Males have rigid upper incisors while the females have rounded upper incisors. Furthermore, the male sex organs also differ greatly between these three genera of hyraxes which may inhibit them from interbreeding.

Before undergoing SRS, transsexual patients possessed unwanted sex organs which they were eager to remove. Hence, they were frigid and not enthusiastic about engaging in sexual activity. In consequence, transsexuals individuals who have undergone SRS are more satisfied with their bodies and experienced less stress when participating in sexual activity. Most of the individuals have reported that they have experienced sexual excitement during sexual activity, including masturbation.

Hematospermia is a rare condition. Semen that has a deep yellow color or is greenish in appearance may be due to medication. Brown semen is mainly a result of infection and inflammation of the prostate gland, urethra, epididymis and seminal vesicles. Other causes of unusual semen color include sexually transmitted infections such as gonorrhea and chlamydia, genital surgery and injury to the male sex organs.

Rogelio discovers a secret apartment under the salon and to his surprise he meets Adriana. She undresses before him revealing her secret: She is a transgender woman. She is actually Adrian, and although she has taken a female identity, she still retains her male sex organs. Adriana agrees to have sex with Rogelio, who accepts the situation, and even takes the passive role during the sexual encounter.

A 1980 protest march at the California State Capitol was reported in an Associated Press article. The National Organization of Circumcision Information Resource Centers (NOCIRC) was formed by Marilyn Milos, R.N., in 1985. The organization's stated objective is to secure the birthright of male, female, and intersex children and babies to keep their sex organs intact. Protest rallies have been held in the US and other areas.

The development of the reproductive system is a part of prenatal development, and concerns the sex organs. It is a part of the stages of sexual differentiation. Because its location, to a large extent, overlaps the urinary system, the development of them can also be described together as the development of the urinary and reproductive organs. The reproductive organs are developed from the intermediate mesoderm.

Copulation is the union of the male and female sex organs, the innate sexual activity specifically organized to transmit male sperm into the body of the female. In non-primate mammals (for example, rodents, canines, felines, bovines, and equines), the anatomy of the reproductive organs and some circuits of the nervous system are specifically organized for heterosexual copulation.Knobil E., Neill J.D. (Eds). The physiology of reproduction.

Lillie was also a pioneer in the study of sex steroids in sexual differentiation. He published "The Theory of the Free-martin" in Science in 1917, which found that sex steroids in the blood controlled differentiation. Free-martins, sterile female cows born without sex organs, were a perplexing issue for cattle ranchers. Lillie found that free-martins formed when twins shared the same placenta.

The external male sex organs are subject to sexual selection by the female. The male may rub the female's abdomen with its valva during mating. Successful sperm transfer depends upon whether the male spermatophore will fit into the opening of the female ductus seminalis. In a study of sex pheromones, Aglaope infausta was one of the species attracted by tortricids pheromones and caught in the traps.

Similar sets of muscles line the gut, and their actions move digesting food toward the worm's anus. Earthworms are hermaphrodites: each carries male and female sex organs. As invertebrates, they lack a true skeleton, but maintain their structure with fluid-filled coelom chambers that function as a hydrostatic skeleton. "Earthworm" is the common name for the largest members of Oligochaeta (which is a class or subclass depending on the author).

That is, the growth rate on the side of the stem which is being touched is slower than on the side opposite the touch. The resultant growth pattern is to attach and sometimes curl around the object which is touching the plant. However, flowering plants have also been observed to move or grow their sex organs toward a pollinator that lands on the flower, as in Portulaca grandiflora.

In bryophytes (mosses, liverworts, and hornworts), the gametophyte is the most visible stage of the life cycle. The bryophyte gametophyte is longer lived, nutritionally independent, and the sporophytes are typically attached to the gametophytes and dependent on them. When a moss spore germinates it grows to produce a filament of cells (called the protonema). The mature gametophyte of mosses develops into leafy shoots that produce sex organs (gametangia) that produce gametes.
|
|
This is a transitory stage in the life of a moss, but from the protonema grows the gametophore ("gamete-bearer") that is structurally differentiated into stems and leaves. A single mat of protonemata may develop several gametophore shoots, resulting in a clump of moss. From the tips of the gametophore stems or branches develop the sex organs of the mosses. The female organs are known as archegonia (sing.

The surrounding leaves in some mosses form a splash cup, allowing the sperm contained in the cup to be splashed to neighboring stalks by falling water droplets. Mosses can be either dioicous (compare dioecious in seed plants) or monoicous (compare monoecious). In dioicous mosses, male and female sex organs are borne on different gametophyte plants. In monoicous (also called autoicous) mosses, both are borne on the same plant.

There are many long rhizoids on the underside of the thallus but no ventral scales. Pellia epiphylla is monoicous, with both male and female sex organs on the same thallus. The small male organs are scattered along the midrib while the female organs grow near the tip of the thallus and are surrounded by a flap. The plant produces spherical, greenish-black capsules which are borne on stalks known as setae.

Dodson became active in the sex-positive movement in the late 1960s. Dodson used the Hitachi Magic Wand, a powerful main-powered vibrator, in demonstrations and instructional classes to instruct women regarding self-pleasure techniques. She recommended women put a small towel over their sex organs in order to dull the sensation of the vibrator and prolong the pleasurable experience. Her technique became known as the Betty Dodson Method.

Pubic hair is terminal body hair that is found in the genital area of adolescent and adult humans. The hair is located on and around the sex organs and sometimes at the top of the inside of the thighs. In the pubic region around the pubis bone, it is known as a pubic patch. Pubic hair is found on the scrotum in the male and on the vulva in the female.

Megapitaria squalida is gonochoric, which is to say that there are two sexes, and individuals are either male or female. Some populations show significantly higher numbers of females than males. Hermaphrodites, individuals containing both types of sex organs, are present, and even common in some populations. One study suggests that differing sex ratios and the amount of hermaphroditism in various populations may be the result of fishing pressures.

It will only grow in the 15-35 °C range. Mild winters correlate with higher infestations and lower crop yields, possibly due to decreased temperatures inducing the development of sex organs in the oomycete. Losses can be combated by destroying diseased fronds and exposing thalli to the air for 3–4 hours daily. The oospores can be spread in contaminated organic matter and the sporangia can spread through the water.

Cavett did a two-part show on pornography; both parts were taped the same day and shown on two nights. During the first part, he discussed the depiction of oral sex in movies and made a parenthetical utterance: "oral-genital sex...mouth on sex organs." A flap ensued when executives demanded that the censor cut the second phrase. An angry Cavett described the ongoing situation at the beginning of the second part, reusing the phrase.

Powelliphanta can live for 20 years or more, and are slow to mature, reaching sexual maturity around 5–6 years of age. They are hermaphrodites, having both male and female sex organs. They lay 5 to 10 large (bean-sized) eggs a year, which have a thin pink calcium carbonate shell, like a tiny bird's egg. Eggs take 2–6 months to hatch in lowland species, 12–14 months for high-altitude species.

Single gametophore of Physcomitrella patens The word gametophore, also known as gametangiophore, is composed of gametangium and "phore" (Greek Φορά, "to be carried").Bryological Glossary In moss and fern (Archegoniata) the gametophore is the bearer of the sex organs (gametangia), the female archegonia and the male antheridia. If both the archegonia and antheridia are arranged at the same plant, they are called monoicous. If there are female and male plants they are called dioicous.

Despite inhabiting the same hosts, T. discolor and T. ovis are distinct species. The size of male and female T. discolor whipworms are 33.9-50.68mm and 36.0—59.0mm respectively. The spicule of T. discolor is 0.94-1.30mm long and has a rounded tip, whereas the spicule of T. ovis is 4.18-5.62mm long and has a pointed tip. In addition to the spicule, the female sex organs can be used to differentiate the two species.

Despite the presence of both sex organs, it is thought unlikely that both are simultaneously active. Panga are slow to reach sexual maturity, with a minimum population doubling time of 4.5–14 years. In other countries, the name panga may refer to a different species. In Indonesia, it refers to Megalaspis cordyla, in Spain, France, the Netherlands and Poland it refers to Pangasius hypophthalmus, and in Kenya it refers to Trichiurus lepturus.

Blue-tailed damselflies (Ischnura elegans) mating In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms, usually for the purposes of sexual reproduction. Some definitions limit the term to pairing between animals, while other definitions extend the term to mating in plants and fungi. Fertilization is the fusion of two gametes. Copulation is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization.

"The narrative has been extended to an etiological theory, which Lawrence (2007b) has called "the brainsex theory of transsexualism." The transsexual advocacy website, transsexual.org, puts this theory succinctly: 'A transsexual is a person in which the sex-related structures of the brain that define gender identity are exactly opposite the physical sex organs of the body.'" Proponents of the brainsex theory of transsexualism draw a distinction between "brain sex" and "anatomical sex".

One leaflet of a set is connected by a petiole to the stem while the other leaflets in the set are connected to that terminal leaflet. The plant produces a five-petaled white flower, each flower about one inch (25 mm) in diameter with five petals. The flowers exhibit a terminal inflorescence with one to five flowers per young stem. The flowers are hermaphrodites and have both female and male sex organs.

Caterpillar prolegs on Papilio machaon The abdomen, which is less sclerotized than the thorax, consists of 10 segments with membranes in between, allowing for articulated movement. The sternum, on the first segment, is small in some families and is completely absent in others. The last two or three segments form the external parts of the species' sex organs. The genitalia of Lepidoptera are highly varied and are often the only means of differentiating between species.

She recommended women put a small towel over their sex organs in order to dull the sensation of the vibrator and prolong the pleasurable experience. Her technique became known as the Betty Dodson Method. Her sessions were known as Bodysex workshops and featured 15 naked women in supine position, each using a Magic Wand simultaneously to aid in masturbation. She provided a Magic Wand to each woman for these two-hour masturbation sessions.

Twelve percent of all infertility cases are a result of a woman either being underweight or overweight. Fat cells produce estrogen, in addition to the primary sex organs. Too much body fat causes production of too much estrogen and the body begins to react as if it is on birth control, limiting the odds of getting pregnant. Too little body fat causes insufficient production of estrogen and disruption of the menstrual cycle.

Sebaceous and apocrine glands become active at puberty. This, as well as many apocrine glands being close to the sex organs, points to a role related to mating. Compared to other primates, humans have extensive axillary hair and have many odor producing sources, in particular many apocrine glands. In women, the sense of olfaction is strongest around the time of ovulation, significantly stronger than during other phases of the menstrual cycle and also stronger than the sense in males.

There is a record of a hermaphroditic specimen with an ovary on its right side and a testis on its left. Early in development, the embryos are sexually undifferentiated, unpigmented, and possess filamentous external gills; the external yolk sac in this stage weighs . Recognizable sex organs develop by an embryonic length of , and tissue differentiation is complete by a length of . Body pigmentation appears when the embryo is long; the external gills regress at around the same time.

They are one of the world's deepest living apex predators, and will not hesitate to eat anything they meet, including their own kind. Their larvae were originally believed to represent a distinct genus (Macristium) and even family. The two Bathysaurid species, Bathysaurus mollis and Bathysaurus ferox are hermaphrodites, meaning they sport both male and female sex organs, but not much is known about their mating and breeding habits due to the great depth the two species live at.

Cortisol inhibition, and as a result, excess androgen release can lead to a variety of symptoms. Other symptoms come about as a result of increased levels of circulating androgen. Androgen is a steroid hormone, generally associated with development of male sex organs and secondary male sex characteristics The symptoms associated with Cortisone Reductase Deficiency are often linked with Polycystic Ovary Syndrome (PCOS) in females. The symptoms of PCOS include excessive hair growth, oligomenorrhea, amenorrhea, and infertility.

The sex organs are developed in pairs from the adaxial nodal cell at the upper nodes of the primary lateral branches, the oogonium being formed above the antheridium. They are sufficiently large to be easily seen with the naked eye, especially the bright orange or red antheridium. Many species are dioecious. In others the monoecious condition is complicated by the development of the antheridium before the formation of the oogonium, thus preventing fertilization by antherozoids of the same alga.

An androgen (from Greek andr-, the stem of the word meaning "man") is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. This includes the embryological development of the primary male sex organs, and the development of male secondary sex characteristics at puberty. Androgens are synthesized in the testes, the ovaries, and the adrenal glands. Androgens increase in both males and females during puberty.

A long incision located on the right abdominal wall, and the absence of internal organs, indicated that the body had been eviscerated post-mortem, possibly in an effort to preserve the remains. A bundle of herbs found within the body cavity also supported this conclusion. Further research revealed that the child had been around 30 months old at the time of death, though gender could not be determined due to poor preservation of the sex organs.

Phaeoceros laevis, the smooth hornwort, is a species of hornwort of the genus Phaeoceros. It is commonly found in areas where moisture is plentiful, such as moist soils in fields, the banks of streams and rivers or inundated beneath the surface of the rivers. It grows to a maximum height of about 5 millimetres and the plants are monoecious; the sex organs are visible on the dorsal surface. The thallus is nearly flat on the upper surface.

Snails collected in Ghana for food Like almost all pulmonate gastropods, these snails are hermaphrodites, having male and female sex organs. Each snail lays up to 1200 eggs per year. Achatina achatina is an important source of animal protein for West African forest-dwelling ethnic groups, and there is potential for commercial farming. This species' substantial size and potential for rapid population growth can make the snail a serious pest when introduced to non- native ecosystems.

Jonel's costume, for example, is made of stretch vinyl and is airbrushed to create a semi-nude effect; her bright red wig is made of expanded foam. Faun has fur on his pants which is made from toothbrush bristles, human hair, and yak fur. Molinier's long velvet dress was created by using a stencil and net onto which black silicone was applied. Though some characters are made to look entirely nude, the sex organs are fake pieces.

Most of the body is transparent or translucent, with a whitish or greenish tinge. The (usually) four large flat sex organs (gonads) are attached to the four radial canals, and are usually opaque white. The many tentacles each contain thousands of cells called cnidocytes, which contain nematocysts (also known as cnidocysts), and are used to capture prey and pass it to the mouth. Food is taken in the mouth opening, and waste is finally expelled out of the same opening.
|
|
Sexual differentiation starts on the internal sex organs at about 5 weeks of gestation, resulting in the formation of either testes in males, or ovaries in females. If testes are formed, they begin to secrete androgens that affect the external genital development at about week 8 or 9 of gestation. The urogenital folds form the labia minora in females, or penile shaft in males. The labioscrotal swellings become the labia majora in females, or they fuse to become the scrotum in males.

The terms genital modification and genital mutilation can refer to permanent or temporary changes to human sex organs. Some forms of genital alteration are performed on adults with their informed consent at their own behest, usually for aesthetic reasons or to enhance stimulation. However, other forms are performed on people who do not give informed consent, including infants or children. Any of these procedures may be considered modifications or mutilations in different cultural contexts and by different groups of people.

This was followed by Lili Elbe in Dresden during 1930–1931. She started with the removal of her original sex organs, the operation supervised by Dr. Magnus Hirschfeld. Lili went on to have four more subsequent operations that included an orchiectomy, an ovary transplant, a penectomy, and ultimately an unsuccessful uterine transplant, the rejection of which resulted in death. An earlier known recipient of this was Magnus Hirschfeld's housekeeper,Magnus Hirschfeld, Zeitschrift für Sexualwissenschaft, 1908 but their identity is unclear at this time.

A term whose meaning is synonymous with eurotophobia is kolpophobia; however; the scope of kolpophobia can sometimes be broader, allowing for the inclusion of all sex organs. Although eurotophobia does not have an interlingual classical compound, kolpophobia has a Greek etymological derivation with the prefix kolpo meaning a fold that usually alludes to the vulva. Eurotophobia is a hyponym of genitophobia. On the other hand, the term vaginaphobia is used to denote fear of female genitals in the context of sexual orientation.

Sterilizing disables the sex organs of the individual, making it impossible to reproduce. Procreation became a privilege because only authorized individuals were allowed to produce offspring—their characteristics were considered specifically desirable. Although sterilization in the United States was more limited than it was in Germany, German racial hygienists highlighted that sterilization practices in some areas of the United States were more extreme than those in Nazi Germany. The International Federation of Eugenic Organization held a conference in the Netherlands in 1936.

Surgery for intersex conditions have been practiced in Iran since the 1930s. In 1963, Ayatollah Ruhollah Khomeini wrote a book in which he stated that there was no religious restriction on corrective surgery for intersex individuals, though this did not apply to those without physical ambiguity in sex organs. At the time Khomeini was a radical, anti-Shah revolutionary and his fatwas did not carry any weight with the Imperial government, which did not have any specific policies regarding transgender individuals.

The scholar Jane Burns also writes that fabliaux "draw attention to the rich mythical heritage behind the medieval association of mouth and vagina". In contemporary English literature similar freedom with obscenity can be found. Chaucer, for example, frequently alluded to both male and female sex organs, often in slang, in The Canterbury Tales. For example, "The Nun's Priest's Tale" talks of the priest's "coillons" (bollocks), while in his tale, the pardoner tells the priest he can kiss his "olde breech" (underpants).

He died in Deyelsdorf. His name is associated with the "Mauriceau–Smellie–Veit maneuver", a procedure defined as a classical method of assisted breech delivery. The birthing maneuver is named along with obstetricians François Mauriceau (1637–1709) and William Smellie (1697–1763), although it was first described by Jacques Guillemeau (1550–1613) in a 1609 treatise called De l'accouchement hereux des femmes. Among his written works was a treatise on diseases of the female sex organs titled Krankheiten der weiblichen Geschlechtsorgane: Puerperalkrankheiten.

The binnaum does not contribute genetically to the offspring, however. The ejaculate of Newcomers is referred to as "Aklafluid". The specific physical mechanics of the Tenctonese sex act are not explicitly stated, but their sex organs are implied to be radically different from those used in human reproduction. In the original movie, Matt tries to explain to George how a condom works by unfolding it over his fingers and loosely describing that it stretches, George is amazed that it can fit.

Light micrograph of a whole-mount slide of an alt=Light micrograph of a whole-mount slide of an oogonium and antheridium of Chara Chara reproduces vegetatively and sexually. Vegetative reproduction takes place by tubers, amylum stars and secondary protonemata. The sex organs are a multicellular and jacketed globule or antheridium (male) and nucule or archegonium (female). The antheridia and archegonia may occur on separate plants (dioicy), together on the same plant (conjoined monoicy) or separately on the same plant (sejoined monoicy).

In typical prenatal development, sex organs originate from a common primordium during early gestation and differentiate into male or female sexes. The SRY gene, usually located on the Y chromosome and encoding the testis determining factor, determines the direction of this differentiation. The absence of it allows the gonads to continue to develop into ovaries. Thereafter, the development of the internal, and external reproductive organs is determined by hormones produced by certain fetal gonads (ovaries or testes) and the cells' response to them.

Male transsexual gene link found BBC News 26 October 2008 (accessed 26 October 2008) Research suggests that the same hormones that promote the differentiation of sex organs in utero also elicit puberty and influence the development of gender identity. Different amounts of these male or female sex hormones within a person can result in behavior and external genitalia that do not match up with the norm of their sex assigned at birth, and in a person acting and looking like their identified gender.

Precocious puberty is the early development of phenotypical sex organs before the age of 8 in girls and 9 in boys. In medicine, precocious puberty is puberty occurring at an unusually early age. In most cases, the process is normal in every aspect except the unusually early age and simply represents a variation of normal development. In a minority of children with precocious puberty, the early development is triggered by a disease such as a tumor or injury of the brain.

Usually, when the female is ready to mate, she may let the male catch her, at which point he will grasp her by biting a fold of her skin behind her neck. The male will then position his tail underneath the female's tail near her vent. Males have two sex organs, known as hemipenes, which are normally kept within the body, but are everted from his vent for mating. Males seem to alternate between the left and right hemipenis on successive matings.

In a 1996 press release, NOCIRC stated that "We expect this professional organization [the American Academy of Pediatrics] that is concerned with the health of infants and children to reveal the harm of genital cutting and to protect every child's birthright to keep his or her sex organs intact." The American Academy of Pediatrics said in 1999 that the perceived benefits of circumcision are not sufficient to recommend routine neonatal circumcision, but that it should be the decision of informed parents.

In this region populations have experienced considerable declines since 1978. Droughts in the Matobo National Park are considered as a causal factor in this decline. However, predation is also reported to be high in this region and this study reported a 52-61% mortality rate within the first year of life for the bush hyrax. The bush hyraxes, Heterohyrax brucei, are known to live with rock hyraxes, Procavia capensis and Procavia johnstoni However, different species of hyraxes do not interbreed because their sex organs vary significantly.

Schema of arteries arising from the iliac and femoral arteries The pudendal arteries are a group of arteries which supply many of the muscles and organs of the pelvic cavity. The arteries include the internal pudendal artery, the superficial external pudendal artery, and the deep external pudendal artery. The internal pudendal artery branches off the internal iliac artery, the main artery of the pelvis, and supplies blood to the sex organs. The internal pudendal artery gives rise to the perineal artery and the inferior rectal artery.

The development of the urinary system begins during prenatal development, and relates to the development of the urogenital system – both the organs of the urinary system and the sex organs of the reproductive system. The development continues as a part of sexual differentiation. The urinary and reproductive organs are developed from the intermediate mesoderm. The permanent organs of the adult are preceded by a set of structures which are purely embryonic, and which with the exception of the ducts disappear almost entirely before birth.

The vulva (plural: vulvas or vulvae; derived from Latin for wrapper or covering) consists of the external female sex organs. The vulva includes the mons pubis (or mons veneris), labia majora, labia minora, clitoris, vestibular bulbs, vulval vestibule, urinary meatus, the vaginal opening, hymen, and Bartholin's and Skene's vestibular glands. The urinary meatus is also included as it opens into the vulval vestibule. Other features of the vulva include the pudendal cleft, sebaceous glands, the urogenital triangle (anterior part of the perineum), and pubic hair.

The lifetime of adult worms varies tremendously from one species to another but is generally in the range of 1 to 8 years (see following table). This lifetime of several years is a result of their ability to manipulate the immune response of their hosts by secreting immunomodulatory products. Helminths can be either hermaphroditic (having the sex organs of both sexes), like tapeworms and flukes (not including the blood fluke), or have their sexes differentiated, like the roundworms. All helminths produce eggs (also called ova) for reproduction.

The sex organs in the induced hermaphroditic flowers become sterile as a result of infection, a process known as "parasitic castration". Ovaries become sterile because they become replaced with teliospores and form "smut balls", making the ovary unable to set seed. The anthers, however, do not show outward signs of teliospore production, but are still effectively sterile because they tend to be small and immature. Consequently, both male and female reproductive organs within induced hermaphroditic flowers of buffalograss become parasitically castrated, but for different reasons.

Stylized cutaway diagram of an animal cell (with flagella) The kingdom Animalia contains multicellular organisms that are heterotrophic and motile (although some have secondarily adopted a sessile lifestyle). Most animals have bodies differentiated into separate tissues and these animals are also known as eumetazoans. They have an internal digestive chamber, with one or two openings; the gametes are produced in multicellular sex organs, and the zygotes include a blastula stage in their embryonic development. Metazoans do not include the sponges, which have undifferentiated cells.

Smith has fought to improve conditions for racing greyhounds in Florida, filing legislation in 2017 to ban the use of anabolic steroids in the industry. Florida is one of the few places in the United States where greyhound racing persists, and the use of steroids in racing dogs has caused adverse effects such as increased aggression and the development of male sex organs in female dogs. Smith's bill passed the House overwhelmingly, but failed in the Senate. Smith has re-filed the bill for the 2018 session.

From the protonema grows the adult gametophyte, which is the persistent and independent stage in the life cycle. This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter, and several layers of cells in thickness. It is green or yellow- green from the chlorophyll in its cells, or bluish-green when colonies of cyanobacteria grow inside the plant. When the gametophyte has grown to its adult size, it produces the sex organs of the hornwort.

Most plants are monoecious, with both sex organs on the same plant, but some plants (even within the same species) are dioecious, with separate male and female gametophytes. The female organs are known as archegonia (singular archegonium) and the male organs are known as antheridia (singular antheridium). Both kinds of organs develop just below the surface of the plant and are only later exposed by disintegration of the overlying cells. The biflagellate sperm must swim from the antheridia, or else be splashed to the archegonia.

His better known publications were a treatise on pelvic tissue diseases called Die Krankheiten des Beckenbindegewebes, and an 1896 work on diseases of the female sex organs titled Die Erkrankungen der weiblichen Geschlechtsorgane, the latter being co-authored with Rudolf Chrobak. Rosthorn is credited with the design of a specialized mask for application of chloroform anesthesia. Vienna Virtual Museum of the History of Anesthesia and Intensive Care Medicine Rostorn's wife was the opera singer Helene Wiet whom he married in 1899.Kornberger, Monika (2015).

Concentrations in surface water alone are not sufficient to assess the risk of negative environmental effects in the aquatic environment. Synthetic hormones are endocrine disruptors. Thus, estrogenic compounds like ethinylestradiol (estrogen hormone) at concentrations < 1 ng per litre may cause both vitellogenin production (a frequently used index for feminization of male fish), and structural change in their sex organs. It has also been demonstrated that fish exposed to sewage treatment plant (STP) effluent can take up and concentrate estrogenic compounds, including ethinylestradiol, to very high internal levels.

"It may have been mischievous to piss in the snow, but it was damn hard work to end up with the 12 bronzes", Chadwick recalled. "Piss Flowers took two years, largely because I had to find £12,000 to make them". The artist "sold herself" to make a programme about Frida Kahlo for the BBC in order to fund the work. The use of a flower as the form was significant for Chadwick because they are the bisexual reproductive organs of plants containing both male and female sex organs.

Transgender people in Taiwan need to undergo genital surgery (removal of primary sex organs) in order to register gender change on both the identity card and the birth certificate. The surgery requires approval of two psychiatrists, and the procedure is not covered by the National Health Insurance. The government conducted public consultations on the elimination of surgery requirements back in 2015, but no concrete changes have been made since then. In 2018, the government unveiled the new chip-embedded identity card, scheduled to be issued in late 2020.

Puberty is the process of physical changes through which a child's body matures into an adult body capable of sexual reproduction. It is initiated by hormonal signals from the brain to the gonads: the ovaries in a girl, the testes in a boy. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Physical growth—height and weight—accelerates in the first half of puberty and is completed when an adult body has been developed.
|
|
Before puberty, the external sex organs, known as primary sexual characteristics, are sex characteristics that distinguish boys and girls. Puberty leads to sexual dimorphism through the development of the secondary sex characteristics, which further distinguish the sexes. On average, girls begin puberty at ages 10–11 and complete puberty at ages 15–17; boys generally begin puberty at ages 11–12 and complete puberty at ages 16–17. The major landmark of puberty for females is menarche, the onset of menstruation, which occurs on average between ages 12 and 13.

The lack and impairment of insulin receptor functionality leads to an inability to regulate blood glucose levels through severe insulin resistance. This will ultimately lead to affected development of tissues and organs throughout the body. In addition to the physical abnormalities, leprechaunism is also characterized by endocrine system abnormalities that can lead to conditions such as hyperglycemia (high blood glucose levels), hypoglycemia (low blood glucose levels), hyperinsulemia (high blood insulin levels), and the enlargement of certain sex organs such as the penis in males, and the clitoris in females.

Gonads start developing as a common primordium (an organ in the earliest stage of development), in the form of gonadal ridges, and only later are differentiated to male or female sex organs. The presence of the SRY gene, located on the Y chromosome and encoding the testis determining factor, determines male sexual differentiation. In the absence of the SRY gene from the Y chromosome, the female sex (ovaries instead of testes) will develop. The development of the gonads is a part of the development of the urinary and reproductive organs.

He studied the mechanical functions of the skeleton and the muscular forces that are applied to it in a manner that prefigured the modern science of biomechanics. He drew the heart and vascular system, the sex organs and other internal organs, making one of the first scientific drawings of a fetus in utero. The drawings and notation are far ahead of their time, and if published would undoubtedly have made a major contribution to medical science.Alastair Sooke, Daily Telegraph, 28 July 2013, "Leonardo da Vinci: Anatomy of an artist", accessed 29 July 2013.

Similarly the works also connect how these changes affect or would affect labor roles. Shulamith's book created an understanding for gender transformation, and these themes are still a basis of cyberfeminist writing presently. Themes in The Dialectic of Sex have ties in xenofeminism as well. Firestone's desire to free women from the burden of reproduction and eliminate the use of sex organs to define an individual's identity has connections to the ambition of xenofeminists to create a society in which all individuals are not assigned traits based on their supposed sex.

A form of TTD without photosensitivity also exists, although its mechanism is unclear. The MPLKIP gene has been associated with this form of TTD, although it accounts for only 20% of all known cases of the non-photosensitive form of TTD, and the function of its gene product is also unclear. Mutations in the TTDN1 gene explain another 10% of non-photosensitive TTD. The function of the gene product of TTDN1 is unknown, but the sex organs of individuals with this form of TTD often produce no hormones, a condition known as hypogonadism.

Talavera thorelli is, along with the other species in the genus, relatively small - and many are fairly similar to one another, as they can be different colours. For accurate identification, there must be close examination of the sex organs of the mature spider, the female epigyne and the male pedipalps on the last joints. The body is divided into an abdomen and a front part of the body (prosoma or cephalothorax). The head has eight eyes, two unusually large at the front and centre, and two smaller on the sides.

In 1970, Philippine high schools and colleges began to include teachings related to public health, sexually transmitted diseases, and limited information on human reproduction and human sexuality in the curriculum for science courses, such as biology. The limitation was truncated by the Filipino tradition of not explicitly mentioning or showing images of the male and female sex organs even for educational purposes. In 1972, the government of Ferdinand Marcos formally offered sexual education programs at all levels of education. Human sexual development and population were topics in science and biology subjects in elementary schools.

In this case the two types of sex organs usually arise from different points on the lateral branches. All cells of the Charales are haploid except for the fertilized zygote, the large single cell in the interior of the oogonium, which becomes enclosed in a thickened hard wall to form an oospore that awaits favorable conditions for germination. Upon germination the diploid oospore undergoes meiosis, producing four haploid nuclei. A septum divides a small apical cell with one haploid nucleus from a large basal cell containing the other three nuclei, which will slowly degenerate.

An example of a mutation in serotonin was found in a species of Nematodes. The serotonin caused their tails to curl during mating, when the mutation occurred the tails did not curl. Without the curling of the tail the nematode was unlikely to find the hermaphrodites sex organs to procreate, and results in less of that nematodes sperm being spread to other offspring. Another example is when the D1 dopamine receptor has a mutation on it; the arousal of a Drosophila melanogaster is increased, which also increases the courtship of the animal.

In both males and females, the sex organs consist of three structures: the gonads, the internal genitalia, and the external genitalia. In males, the gonads are the testes and in females they are the ovaries. These are the organs that produce gametes (egg and sperm), the reproductive cells that will eventually meet to form the fertilized egg (zygote). As the zygote divides, it first becomes the embryo (which means 'growing within'), typically between zero and eight weeks, then from the eighth week until birth, it is considered the fetus (which means 'unborn offspring').

Dodson's books include Liberating Masturbation, Sex for One: The Joy of Self-Loving and Orgasms for Two: the Joy of Partnersex. She also produced four videos: Selfloving: Portrait of a Sexual Seminar, Celebrating Orgasm: Women's Private Selfloving Sessions, Viva la Vulva: Women's Sex Organs Revealed and The Orgasm Doctor: Two Private Hands-on Sex Coaching Sessions. In 2006, Carlin Ross, a former corporate lawyer, met Betty Dodson for an interview and became her business partner. They created an online sexuality portal for women under the brand Dodson and Ross.

Yossi Loya and Kazuhiko Sakai, "Bidirectional sex change in mushroom stony corals", Proceedings of the Royal Society B, 22 October 2008 Chickens can sometimes undergo natural sex changes. Normally, female chickens have just one functional ovary, on their left side. Although two sex organs are present during the embryonic stages of all birds, once a chicken's female hormones come into effect, it typically develops only the left ovary. The right gonad, which has yet to be defined as an ovary, testes, or both (called an ovotestis), typically remains dormant.

Prothallus of the tree fern Dicksonia antarctica (note new moss plants for scale) Spore-bearing plants, like all plants, go through a life-cycle of alternation of generations. The fully grown sporophyte, what is commonly referred to as the fern, produces genetically unique spores in the sori by meiosis. The haploid spores fall from the sporophyte and germinate by mitosis, given the right conditions, into the gametophyte stage, the prothallus. The prothallus develops independently for several weeks; it grows sex organs that produce ova (archegonia) and flagellated sperm (antheridia).

Natural chimeras are almost never detected unless they exhibit abnormalities such as male/female or hermaphrodite characteristics or uneven skin pigmentation. The most noticeable are some male tortoiseshell cats and calico cats (although most male tortoiseshells have an extra X chromosome responsible for the colouration) or animals with ambiguous sex organs. The existence of chimerism is problematic for DNA testing, a fact with implications for family and criminal law. The Lydia Fairchild case, for example, was brought to court after DNA testing apparently showed that her children could not be hers.

The intermediate lobe synthesizes and secretes melanocyte-stimulating hormone. The posterior pituitary (or neurohypophysis) is a lobe of the gland that is functionally connected to the hypothalamus by the median eminence via a small tube called the pituitary stalk (also called the infundibular stalk or the infundibulum). Hormones secreted from the pituitary gland help to control growth, blood pressure, energy management, all functions of the sex organs, thyroid glands and metabolism as well as some aspects of pregnancy, childbirth, breastfeeding, water/salt concentration at the kidneys, temperature regulation and pain relief.

The book has been well received by both clinicians and intersex groups. Gary Berkovitz, writing in the New England Journal of Medicine states that Karkazis's analysis is fair, compelling, and eloquent; "Current consensus guidelines recommend early separation of the vagina and urethra for female subjects with abnormalities in the formation of the sex organs... Karkazis presents a compelling argument for the deferment of subsequent surgery until the patient is able to decide."Fixing Sex: Intersex, Medical Authority, and Lived Experience, New England Journal of Medicine, April 16, 2009.

In the Amazon rainforest, entomologist Dr. James Atherton hopes to discover new species of insects and arachnids. In a Venezuelan tepui, he captures an aggressive new species of spider, which is revealed to be lacking sex organs, thus, making it a drone or soldier - atypical in spiders. A fertile non-drone male of the same species bites nature photographer Jerry Manley, who has a massive seizure from the venom and dies. The scientists bring his body back to the United States, blaming his death on a fever - unaware the spider has crawled into the coffin.

Deepsea lizardfish are hermaphrodites, bearing both male and female sex organs, thought to be an adaptation to low population densities. Mature gonads found in samples from November to January off the coast of Virginia show that their reproduction is synchronous, a means of maximizing breeding population densities without increasing the size of the feeding population. Mean fecundity rates of around 32,000 ova per fish were observed for eight specimens. Not much is known about their mating habits; however, larval deepsea lizardfish have been recorded at the surface of the ocean.

Koro is a culture-bound syndrome delusional disorder in which an individual has an overpowering belief that one's sex organs are retracting and will disappear, despite the lack of any true longstanding changes to the genitals. Koro is also known as shrinking penis, and it is listed in the Diagnostic and Statistical Manual of Mental Disorders. The syndrome occurs worldwide, and mass hysteria of genital-shrinkage anxiety has a history in Africa, Asia and Europe. In the United States and Europe, the syndrome is commonly known as genital retraction syndrome.

She was also known for arguing against gender self- identification. Speaking on the subject of gender and sexuality, Berns stated: "You don't get 'assigned' reproductive organs...males are defined by their biological sex organs. Likewise, homosexuals are people who are attracted to the same biological sex." She described trans women as "blackface actors" and "men who get sexual kicks from being treated like women", said that "trans women are men", that "there is no such thing as a lesbian with a penis", and that she'd "rather be rude than a fucking liar".

The implementation of self- pollination significantly reduces genetic variation in a population, and an established population of identical progeny presents limited opportunity for evolution on a genomic level throughout a species. The plant combats this through the utilization of both male and female sex organs which provides an environment with low rates of outcrossing through sex-biased genes. The result of low genetic variations in both A. thaliana gametophytes self-fertilization comes from the low rates of outcrossing. The low rates of outcrossing can be overcome by variations of heterogeneity in selection.

Male Hormosira conceptacle Female Hormosira conceptacle This seaweed can reproduce asexually from broken fragments. The attached form also reproduces sexually, and is monoecious. The sex organs (conceptacles) are on the surface of the beads, and are visible to the naked eye as rough-looking dimples. Hormosira produces eggs throughout the year, but its peak reproduction is often confined to July–October (at least in northern New Zealand) when the sea temperature is around 14 °C, as the viability of the eggs can be low in high sea temperatures such as 17–22 °C.

On the underside of the prothallus, the male reproductive organs are located, while the female ones are at the top. The male sex organs are called antheridia and the female ones are called archegonia. When the sperm and the egg has matured and there is enough moisture on the prothallus, the antheridia release the spermatozoa which is attracted by the scent coming from the ripened egg and swims towards it to fertilize it. Once fertilized, the cell can divide and the new baby fern starts to grow with help from the prothallus, which supports it with nutrients.

During mating, the female uses her gynosome to extract sperm and nutrient-filled seminal fluid from the male. A single mating session can last from 40 to 70 hours. The reversal of sex organs may be explained by the lack of nutrients in the cave environment, which makes it evolutionarily useful for the female to extract nutrients from the male. Female Neotrogla drain males of seminal fluid even when they are too young to reproduce, giving weight to this theory, according to entomologist Kazunori Yoshizawa who co-authored the first study of the insects' mating behavior.

In studying adolescent development, adolescence can be defined biologically, as the physical transition marked by the onset of puberty and the termination of physical growth; cognitively, as changes in the ability to think abstractly and multi- dimensionally; or socially, as a period of preparation for adult roles. Major pubertal and biological changes include changes to the sex organs, height, weight, and muscle mass, as well as major changes in brain structure and organization. Cognitive advances encompass both increment in knowledge and in the ability to think abstractly and to reason more effectively. The study of adolescent development often involves interdisciplinary collaborations.

"Get Naked" is a song by American musician Tommy Lee's first solo project Methods of Mayhem, from their album Methods of Mayhem. It features vocals by Fred Durst, Lil' Kim and George Clinton, with turntablism contributed by Beastie Boys associate Mix Master Mike. The U.S. and Australian singles (released in CD and vinyl formats) contain the clean and album versions of the song, along with a b-side ("Narcotic") and media documenting the making of the video. The song contains explicit sexual content, with references to "cum", a "blow-job", a "porno tape", and male and female sex organs.

Sigesbeckia is named for a botanist Johann Georg Siegesbeck, who was a strong critic of Carl Linnaeus's botanic classification system. He was known to refer to it as "Loathsome Harlotry" because of the focus of the system upon the presence of (or lack of) sex organs in plants and their locations and groupings. Siegesbeck tried to refute Linnaeus' sexual classification system, but was unable to provide sound scholastic arguments to support his arguments. In Linnaeus' work, Critica Botanica, he proposed that there should be a link between the plant and the botanist after whom it was named.

Franz von Leydig's work on neural tissue influenced Norwegian zoologist and polar explorer Fridtjof Nansen (1861–1931), who along with Wilhelm His, Sr. (1831–1904) and Auguste-Henri Forel (1848–1931), were the first to establish the anatomical entity of the nerve cell. Chief among Leydig's discoveries is the interstitial cell ("Leydig cells"), a body enclosed in a smooth endoplasmic reticulum and holding lipid granules and crystals, which occur adjacent to the seminiferous tubules of the testes. The cells produce the male hormone testosterone. Leydig had described the interstitial cells in his detailed account of the male sex organs.

They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs (sex organs) and the rectum, while the pelvic floor at the base of the cavity assists in supporting the organs of the abdomen. In mammals, the bony pelvis has a gap in the middle, significantly larger in females than in males. Their young pass through this gap when they are born.

The bryophytes of Antarctica consist of 100 species of mosses, and about 25 species of liverworts. While not being as widespread as lichens, they remain ubiquitous wherever plants can grow, with Ceratodon purpureus being found as far south as 84°30' on Mount Kyffin. Unlike most bryophytes, a majority of Antarctic bryophytes do not enter a diploid sporophyte stage, instead they reproduce asexually or have sex organs on their gametophyte stage. Only 30% of bryophytes on the Peninsular and subantarctic islands have a sporophyte stage, and only 25% of those on the rest of the mainland produce sporophytes.

Before the tablets were discovered, substantial elements of the myth had survived via the writings of Berossus, a 3rd-century BCE Babylonian writer and priest of Bel (Marduk). These were preserved in Alexander Polyhistor's book on Chaldean History, which was reproduced by Eusebius in Book 1 of his Chronicon. In it are described the primeval state of an abyssal darkness and water, the two primeval beings existing therein, said to be of a twofold principle. The description then relates the creation of further beings, partly human but with variants of wings, animal heads and bodies, and some with both sex organs.

When male rats were given low dose levels (>3 mg/kg/day) of vinclozolin, effects such as decreased prostate weight, weight reduction in sex organs, nipple development, and decreased ano- genital distance were noted. At higher dose levels, male sex organ weight decreased further, and sex organ malformations were seen, such as reduced penis size, the appearance of vaginal pouches and hypospadias. In the rat model, it has been shown that the antiandorgenic effects of vinclozolin are most prominent during the developmental stages. In utero, this sensitive period of fetal development occurs between gestation days 16-17.

The right heart is a solid mass of muscle which provides most of the force behind the body's blood circulation. The left heart is much more complex - this heart is made up of an intricate system of thousands of veins that help cleanse the blood in a manner similar to the human kidneys. The sexual organs of the Centauri are in a different location than the human sex organs. Male Centauri have six tentacle-like genital organs that extend out from the sides of the body and "fold" in over the solar plexus when not in use.

Lloyd observed that karezza offered health benefits. For example, he said he knew it to “act like magic in painful menstruation,” and as a remarkable nerve sedative, even curing nervous headache. He also found it one of the best agents “for the benefit and cure of ordinary sexual weaknesses and ailments, including urethritis and prostatitis.” > In successful Karezza the sex-organs become quiet, satisfied, demagnetized, > as perfectly as by the orgasm, while the rest of the body of each partner > glows with a wonderful vigor and conscious joy ... tending to irradiate the > whole being with romantic love; and always with an after-feeling of health, > purity and well-being.

Of the 145 prostitutes who participated, only a select few were further evaluated for their genital anatomy and their physiological responses. In later studies, however, Masters and Johnson recruited 382 women and 312 men from the community. The vast majority of participants were white, they had higher education levels, and most participants were married couples. As well as recording some of the first physiological data from the human body and sex organs during sexual excitation, they also framed their findings and conclusions in language that espoused sex as a healthy and natural activity that could be enjoyed as a source of pleasure and intimacy.

Stages in the development of the clitoris In mammals, sexual differentiation is determined by the sperm that carries either an X or a Y (male) chromosome. The Y chromosome contains a sex-determining gene (SRY) that encodes a transcription factor for the protein TDF (testis determining factor) and triggers the creation of testosterone and Anti-Müllerian hormone for the embryo's development into a male. This differentiation begins about eight or nine weeks after conception. Some sources state that it continues until the twelfth week, while others state that it is clearly evident by the thirteenth week and that the sex organs are fully developed by the sixteenth week.

People with such inclinations may express a compounded desire to substitute audible mentions of the vulva with euphemisms. The extent of the condition varies from person to person, with some feeling a sense of repulsion, others reacting only once evoked, avoidance of thinking about female sex organs or a sense of deep fear. Eurotophobia has also been given an account by Planned Parenthood in the lexicon section of their publications. Rather than being an anomaly, some historical works point to cultures wherein eurotophobic behavior was mainstream, such as those where couples would avoid copulating in illuminated areas to ensure the vulva remained out of sight.

Preece's career started with showings at downtown art walks and group shows, painted shoes for Project Canvas with other artists, and volunteering many hours telling her story of addiction, recovery and passion for art with at-risk youth. In 2012 she again picked up the spray can and created a humorous piece on a Melrose and Fairfax wall, and again with a mural drew complaints from the L.A. City Council for its depiction of sex organs. Her first solo show was in 2013 at Space 1520 in Hollywood. She was asked to be the first female artist to paint a mural on the Roxy Theater in West Hollywood.

For girls, this age ranges from eight to nineteen. For both sexes, these first sexual experiences arise more frequently during the later years as opposed to the earlier years. Ellis then references G.V. Hamilton’s studies that found twenty percent of males and fourteen percent of females have pleasurable experiences with their sex organs before the age of six. This is only supplemented by Ellis’ reference to Katharine Davis’ studies, which found that twenty to twenty-nine percent of boys and forty-nine to fifty-one percent of girls were masturbating by the age of eleven. However, in the next three years after, boys’ percentages exceeded those of girls.

The Latin term genitalia, sometimes anglicized as genitals, is used to describe the externally visible sex organs: in male mammals, the penis and scrotum; and in female mammals, the vulva and its organs. In general zoology, given the great variety in organs, physiologies, and behaviors involved in copulation, male genitalia are more strictly defined as "all male structures that are inserted in the female or that hold her near her gonopore during sperm transfer"; female genitalia are defined as "those parts of the female reproductive tract that make direct contact with male genitalia or male products (sperm, spermatophores) during or immediately after copulation".Eberhard, W.G., 1985.

Since SPR is also expressed in the cells of organisms who do not have exposure to SP as drosophila do, Yapici and her team explored alternative ligands for SPR and found myoinhibitory peptides (MIPs) to be another type of SPR ligand and they appeared to be conserved across a spectrum of invertebrates. Interestingly, MIPs are not derived from male sex organs as SP is, and MIPs are not necessary to promote the switch in behavior post-mating in females, while SP is necessary. Following this work, Yapici and her colleagues decided to patent the idea of targeting the SPR as a method of insect control.

For the American bison, the main cause of illness is malignant catarrhal fever, though brucellosis is a serious concern in the Yellowstone Park bison herd. Bison in the Antelope Island bison herd are regularly inoculated against brucellosis, parasites, Clostridium infection, infectious bovine rhinotracheitis, and bovine vibriosis. The major concerns for illness in European bison are foot-and-mouth disease and balanoposthitis, which affects the male sex organs; a number of parasitic diseases have also been cited as threats. The inbreeding of the species caused by the small population plays a role in a number of genetic defects and immunity to diseases, which in turn poses greater risks to the population.

Normally, the eggs are assumed to be inviable and are discarded. This batch of eggs was left undisturbed by the curator as he had heard about the previous birth in 2001 in Nebraska and wanted to observe whether they would hatch. Other possibilities had been considered for the birth of the Detroit bamboo sharks including thoughts that the sharks had been fertilized by a male and stored the sperm for a period of time, as well as the possibility that the Belle Isle bamboo shark is a hermaphrodite, harboring both male and female sex organs, and capable of fertilizing its own eggs, but that is not confirmed.National Geographic, (2002).

"Walker's Mammals of the World". The Johns Hopkins University Press, 1999 Secondary sexual dimorphic traits allow for sex determination without analysis of the sex organs. In males, the ornamentation at the base of the ear has the capability to erect itself with the assistance from the arrector pili muscle.Nowak. "Walker's Mammals of the World". The Johns Hopkins University Press, 1999 On average females are slightly larger than males by approximately of ten percent when comparing body mass. This variation is also present in the many body proportions including wingspan, head length, ear length, and many other anatomical variations. Despite the larger size observed in the females, M. pusillus is still one of the smaller mammals in the Megachiroptera suborder.

In criminal law, the term has had different meanings at different times and in different jurisdictions. While commonly a mere euphemism for sexual intercourse (not necessarily unlawful), different jurisdictions have defined carnal knowledge (as well as sexual intercourse) as a specific sex act such as contact between a penis and vagina, some laws elaborating this to include even "slight penile penetration of female sex organs". The definition sometimes includes a set of sex acts that include sodomy, while some statutes specifically exclude such acts. Some laws do not define the term, and leave it to the courts to give it meaning, which also allows them to take into account changing community standards.

According to Laqueur, prior to the eighteenth century it was acknowledged that there were physical differences between the sex organs of men and women, but these differences were never made to be of significance; "no one was much interested in looking for evidence of two distinct sexes, at the anatomical and concrete physiological differences between men and women, until such differences became politically important."Laqueur (1999), 10. Until the beginning of the eighteenth century, Laqueur claims, the one-sex model dominated medical and philosophical literature and there was a web of knowledge to support it. Laqueur uses examples from ancient thinkers to help support his claim to the dominance of the one-sex model prior to the eighteenth century.

However, Alexandra also highlighted how the camera frames several woman "in the most lustful way possible", while Loveridge of Anime News Network stated it demonizes female sexuality as all demons in the Sabbath are female and their demon traits are based on their sex organs which then devour the men. Many critics commented about "the remarkable animation style", as reported Pementel. It was considered one of the most "visually striking" anime of all time by Loveridge, while it has been described as "visually enthralling" by Thurm, and "visually stunning" by Matt Kamen for GamesRadar+ and by Frank. Theron Martin of Anime News Network commented, "you won't see a more [...] outlandish visual spectacle in anime this season".

Plants have both male and female sex organs, but half of the flowers of the Ribbonwood do not produce any fertile female organs . Attracted by the scent and colour of the flower, small beetles and thrips are the main floral visitors ; they crawl in and lay their eggs within the center of the flower, which contains the flower's pollen. Within the flower some of the sticky pollen gets trapped on the insect's bodies, and if the next flower they visit is a receptive one, it will pollinate and produce the seeds. While most modern flowering plants produce seeds which have one cotyledon (monocotyledons) or two (dicotyledons), the seedlings of the Ribbonwood have between two and five cotyledons.

Although several of Hollick’s views merited similarities among his colleagues, it was not enough to sway them into approving of his overall methodology. Thus, beginning in 1846, Hollick was condemned by his Antebellum peers to multiple charges of obscenity, leading to two trials, the second of which he failed to show up for. The charges insisted that both Hollick’s papier-mâché mannequin and the distribution of anatomically correct diagrams of sex organs were obscene, edging on pornographic. However, the first charges were eventually dropped due to witnesses dismissal of the mannequin as obscene, but rather informational, which only reaffirmed the widely held belief that Hollick’s teachings provided a fresh, welcoming view of sex.

Medical terminology has shifted not only due to concerns about language, but also a shift to understandings based on genetics. Currently, hermaphroditism is not to be confused with intersex, as the former refers only to a specific phenotypical presentation of sex organs and the latter to a more complex combination of phenotypical and genotypical presentation. Using hermaphrodite to refer to intersex individuals is considered to be stigmatizing and misleading. Hermaphrodite is used for animal and plant species in which the possession of both ovaries and testes is either serial or concurrent, and for living organisms without such gonads but present binary form of reproduction, which is part of the typical life history of those species; intersex has come to be used when this is not the case.

Ambiguous genitalia may appear as a large clitoris or as a small penis. The Quigley scale is a method for describing genital development in AIS. Because there is variation in all of the processes of the development of the sex organs, a child can be born with a sexual anatomy that is typically female or feminine in appearance with a larger-than- average clitoris (clitoral hypertrophy) or typically male or masculine in appearance with a smaller-than-average penis that is open along the underside. The appearance may be quite ambiguous, describable as female genitals with a very large clitoris and partially fused labia, or as male genitals with a very small penis, completely open along the midline ("hypospadic"), and empty scrotum.

Metabolic age is calculated by comparing one's basal metabolic rate to the average of one's chronological age group. Basal metabolic rate is the amount of energy consumed per unit of time when all environmental factors are considered neutral, the digestive system is in a post-absorptive state (meaning that the digestive system is inactive, which requires about twelve hours of fasting in humans), and the energy expenditure is only sufficient to support normal functioning of the vital organs, the heart, lungs, nervous system, kidneys, liver, intestine, sex organs, muscles, and skin. Formulas for estimating basal metabolic rate take into account age, weight, height, activity level, body fat mass, and lean body mass. All the components in the body require various levels of energy to be maintained.

The ACCA directly impacts the criminal aspect of acid attacks, and allows for the death penalty or a level of punishment corresponding to the area of the body affected. If the attack results in a loss of hearing or sight or damages the victim's face, breasts, or sex organs then the perpetrator faces either the death penalty or life sentencing. If any other part of the body is maimed, then the criminal faces 7–14 years of imprisonment in addition to a fine of US$700. Additionally, throwing or attempting to throw acid without causing any physical or mental harm is punishable by this law and could result in a prison term of 3–7 years along with a US$700 fine.

Castration anxiety is the conscious or unconscious fear of losing all or part of the sex organs, or the function of such. In the literal sense, castration anxiety refers to the fear of having one's genitalia disfigured or removed to punish sexual desires of a child. In Freudian psychoanalysis, castration anxiety (Kastrationsangst) refers to an unconscious fear of penile loss originating during the phallic stage of psychosexual development and lasting a lifetime. According to Freud, when the infantile male becomes aware of differences between male and female genitalia he assumes that the female's penis has been removed and becomes anxious that his penis will be cut off by his rival, the father figure, as punishment for desiring the mother figure.

The term transsexual originated in the medical and psychological communities. However, unlike the term transgender, transsexual is not an umbrella term, and many transgender people do not identify as such. Transsexual is a term for AFAB and assigned male at birth (AMAB) people alike who feel their sex organs do not reflect their gender and have chosen to change some aspect of their body; it is an older term, with GLAAD stating that it is "still preferred by some people who have permanently changed – or seek to change – their bodies through medical interventions (including but not limited to hormones and/or surgeries)." The transgender community sometimes uses the term passing to describe a transgender person's ability to appear as the gender they identify with.

The original design of the human/Alien hybrid included a mix of female and male sex organs, which were removed during post-production Special effects company Amalgamated Dynamics Incorporated (ADI) was hired for the film, having previously worked on Alien 3. ADI founders Tom Woodruff Jr. and Alec Gillis also had experience working with Stan Winston on Aliens. ADI based their designs and modifications of the Alien creatures on the film's script, which included the creatures having pointed tails for swimming, making their head domes and chins more pointed, and establishing them to appear more vicious using techniques of camera angles and shot duration. After receiving the director's approval, ADI began to create small sculptures, sketches, paintings, and life-size models.

Two-colored rose chimera A genetic chimerism or chimera (/kaɪˈmɪərə/ or /kɪˈmɪərə/ , also chimaera (chimæra)) is a single organism composed of cells with more than one distinct genotype. In animals, this means an individual derived from two or more zygotes, which can include possessing blood cells of different blood types, subtle variations in form (phenotype) and, if the zygotes were of differing sexes, then even the possession of both female and male sex organs (this is just one of many different phenomena that may result in intersexuality). Animal chimeras are produced by the merger of multiple fertilized eggs. In plant chimeras, however, the distinct types of tissue may originate from the same zygote, and the difference is often due to mutation during ordinary cell division.

With regard to marriage of one who is intersex, if it is an unambiguous case, then according to how he or she is classified, he or she may marry someone of the opposite gender. If it is an ambiguous case, then the marriage of such a person cannot be valid, the reason being that he may be male, in which case how can he marry another male, or may be female, in which case she can't marry another female like her. If this individual is sexually attracted to females and claims to be a man, this is a sign that he is most likely male, and vice versa. Intersex medical interventions are considered permissible to achieve agreement between a person's exterior, chromosomal make-up or sex organs.

In the absence of evidence that respondent is an 'incompetent,' and in the absence of evidence to show that classifying respondent as a male will harm other members of society [...] the court affirms as valid and justified the respondent's position and his personal judgment of being a male." Court records showed that – at 6, he had small ovaries; at 13, his ovarian structure was minimized and he had no breasts and did not menstruate. The psychiatrist testified that "he has both male and female sex organs, but was genetically female, and that since his body secreted male hormones, his female organs did not develop normally." The Philippines National Institutes of Health said "people with congenital adrenal hyperplasia lack an enzyme needed by the adrenal gland to make the hormones cortisol and aldosterone.

Early land plants had sporophytes that produced identical spores (isosporous or homosporous) but the ancestors of the gymnosperms evolved complex heterosporous life cycles in which the spores producing male and female gametophytes were of different sizes, the female megaspores tending to be larger, and fewer in number, than the male microspores. During the Devonian period several plant groups independently evolved heterospory and subsequently the habit of endospory, in which the gametophytes develop in miniaturized form inside the spore wall. By contrast in exosporous plants, including modern ferns, the gametophytes break the spore wall open on germination and develop outside it. The megagametophytes of endosporic plants such as the seed ferns developed within the sporangia of the parent sporophyte, producing a miniature multicellular female gametophyte complete with female sex organs, or archegonia.

Performing well over 300 shows a year, his large catalog of original songs (over 600 and growing) covers a variety of topics such as lost loves, politics, family vacations, hair styles, the joys of Asian cuisine, the sex organs of long-dead French Emperors, how the world cannot live without Sex & Beer, and wishing to have a Monkey Paw. He even successfully makes humorous the mundane daily cycle of waking up, going to work, getting drunk, and going to sleep. In 2008, he was asked by the Green Bay Packers to write a song to play in their stadium. Originally objecting because he did not like sports songs, he went on to write "I Love the Green and Gold," eventually making it into a music video starring himself and featuring Larry the Cable Guy.

Activists who oppose genital modification and mutilation define themselves as intactivists (a portmanteau of "intact" and "activist") or genital integrity activists, who strive to defend the rights of male, female, and intersex children and babies to keep their sex organs intact, to raise awareness about the forced genital mutilations and to prohibit genital mutilation and involuntary or forced circumcision on children internationally. Various organisations have been set up specifically for the purpose, other organisations have stated their support for the movement. Some intactivists consider themselves to be an LGBT social movement, and have participated in LGBT pride parades ever since 2006. In North America, the genital integrity movement primarily focuses on non- therapeutic circumcision of male infants and children and to a lesser but still prevalent extent, intersex surgery.

Ebers Papyrus from the National Library of Medicine The Ebers Papyrus is an Egyptian medical text and is the oldest known record of the human body, dating back to 3000 BC. The Ebers Papyrus describes the body by physical examination and what can be felt. Clinical investigations such as the Pulse, percussion of the body, the recognition of diseased or disordered states. “If thou examinst a swelling of the covering of his belly’s horns above his pudenda (sex organs) then thou shalt place thy finger on it and examine his belly and knock on the fingers (percuss) if thou examinst his that has come out and has arisen by his cough. Then thou shalt say concerning it: it is a swelling of the covering of his belly. It is a disease which I will treat”.

Human males have several physiological adaptations that have evolved in response to pressures from sperm competition, such as the size and shape of the penis. In addition to the anatomy of male sex organs, men have several evolved copulatory behaviors that are proposed to displace rival male semen. For example, males who are at a higher risk of sperm competition (defined as having female partners with high reproductive value, such as being younger and physically attractive) engaged more frequently in semen-displacing behaviors during sexual intercourse than men who were at a lower risk of sperm competition.Goetz, Aaron T.; Shackelford, Todd K.; Weekes-Shackelford, Viviana A.; Euler, Harald A.; Hoier, Sabine; Schmitt, David P.; LaMunyon, Craig W. (2005). “Mate retention, semen displacement, and human sperm competition: A preliminary investigation of tactics to prevent and correct female infidelity”.

Steve Clay Wilson (born July 25, 1941), better known as S. Clay Wilson, is an American underground cartoonist and central figure in the underground comix movement. Wilson attracted attention from readers with aggressively violent and sexually explicit panoramas of lowlife denizens, often depicting the wild escapades of pirates and bikers. He was an early contributor to Zap Comix, and Wilson's artistic audacity has been cited by Robert Crumb as a liberating source of inspiration for Crumb's own work. Recalling when he first saw Wilson's work (in about 1968) Crumb said, "The content was something like I'd never seen before, anywhere, the level of mayhem, violence, dismemberment, naked women, loose body parts, huge, obscene sex organs, a nightmare vision of hell-on-earth never so graphically illustrated before in the history of art.... Suddenly my own work seemed insipid..."The Art of S. Clay Wilson (Ten Speed Press, 2006), p. vii.

'Ali advised the brothers that sex could be determined by site of urination in a practice called hukm al-mabal; if urine exited the male opening, the individual was male, and if it exited the female opening, the individual was female. If it exited both openings simultaneously, as it did in this case, the heir would be given half of a male inheritance and half of a female inheritance. Later, in the thirteenth century CE, Shafi'i law expert Abu Zakariya al-Nawawi ruled that an individual whose sex could not be determined by hukm al-mabal, such as those with urination from both openings or those with no identifiable sex organs, was assigned the intermediary sex category khuntha mushkil. Both Hanafi and Hanbali lawmakers also recognized that puberty could clarify a new dominant sex in intersex individuals who were labeled khuntha, male, or female in childhood.

The same process of sex differentiation concerns other male and female reproductive organs (see List of related male and female reproductive organs), with some organs of both sexes developing similar, yet not identical, structure and functions (like the gonads - male testicles and female ovaries, like male and female urethras, erectile corpus cavernosum penis and prepuce in the penis (foreskin) and the corpus cavernosum clitoridis in the clitoris and (clitoral hood) and their frenula). But other male and female sex organs become absolutely different and unique, like the internal female genitalia. The scrotum and labia majora develop to have both similarities and crucial differences. Like the scrotum, labia majora after puberty may become of a darker color than the skin outside them, and, similarly, also grow pubic hair on their external surface (the female genitals on accompanying photos are shaved to show their structure clearer).

With regard to historical and modern perceptions of the clitoris, the clitoris and the penis were considered equivalent by scholars for more than 2,500 years in all respects except their arrangement. Due to it being frequently omitted from, or misrepresented, in historical and contemporary anatomical texts, it was also subject to a continual cycle of male scholars claiming to have discovered it. The ancient Greeks, ancient Romans, and Greek and Roman generations up to and throughout the Renaissance, were aware that male and female sex organs are anatomically similar, but prominent anatomists such as Galen (129 – c. 200 AD) and Vesalius (1514–1564) regarded the vagina as the structural equivalent of the penis, except for being inverted; Vesalius argued against the existence of the clitoris in normal women, and his anatomical model described how the penis corresponds with the vagina, without a role for the clitoris.

The book soon became notorious for its story of the physical (and emotional) relationship between a working-class man and an upper-class woman, its explicit descriptions of sex, and its use of then-unprintable four-letter words. The story is said to have originated from certain events in Lawrence's own unhappy domestic life, and he took inspiration for the settings of the book from Nottinghamshire, where he grew up. According to some critics, the fling of Lady Ottoline Morrell with "Tiger", a young stonemason who came to carve plinths for her garden statues, also influenced the story.. Lawrence, who at one time considered calling the novel John Thomas and Lady Jane (in reference to the male and female sex organs), made significant alterations to the text and story in the process of its composition. Lawrence read the manuscript of Maurice by E. M. Forster, which was published posthumously in 1971.

On August 24, 2018, an editorial cartoon by MacKay was published in the Hamilton Spectator which depicted Ontario Premier Doug Ford looking directly into the light of an overhead slide projection showing an anatomical cross-section of the male pelvic region, titled "The Penis." Ford is shown positioned with part of the slide projecting male sex organs on his face with a caption stating, "A sex-ed snitch line has been set up to report any funny business." The cartoon was in response to the Progressive Conservative government's repeal of the 2015 Ontario sex education curriculum, and subsequent decision to seek reports of teachers not using the pre-existing curriculum taught between 1992 and 2015. The cartoon provoked criticism and lead to publication in The Hamilton Spectator of letters to the editor, and a column written, in defence of the cartoon, by the newspaper's Editor-in-Chief, Paul Berton.

Although estrogen is best known for its effects on the maturation and differentiation of the primary and secondary sex organs, increasing evidence suggests that its influence extends beyond this system, and its activity in the CNS may initiate, or influence our susceptibility to neurodegenerative decline. Estrogen has been proposed to act as a neuroprotectant at several levels, and it is probable that deprivation of estrogen as a result of menopause exposes the aging or diseased brain to several insults. In addition, estrogen deprivation is likely to initiate or enhance degenerative changes caused by oxidative stress, and to reduce the brain's ability to maintain synaptic connectivity and cholinergic integrity leading to the cognitive decline seen in aged and disease-afflicted individuals. There is sufficient evidence that estradiol is a powerful neuroprotectant which might have use against AD, stroke and Parkinson's disease both in women and men.

Laboratory reports carried out on some mutilated animals have shown unusually high or low levels of vitamins or minerals in tissue samples, and the presence of chemicals not normally found in animals. However, not all mutilated animals display these anomalies, and those that do have slightly different anomalies from one another. On account of the time between death and necropsy, and a lack of background information on specific cattle, investigators have often found it impossible to determine if these variations are connected to the animals' deaths or not. In one case documented by New Mexico police and the FBI, an 11-month-old cross Hereford-Charolais bull, belonging to a Mr. Manuel Gomez of Dulce, New Mexico, was found mutilated on March 24, 1978. It displayed "classic" mutilation signs, including the removal of the rectum and sex organs with what appeared to be “a sharp and precise instrument” and its internal organs were found to be inconsistent with a normal case of death followed by predation.

Several expert opinions were called in determining whether or not Kavanagh’s human rights were violated in the denial of hormones and sex reassignment surgery. One such expert was Diane Watson—the medical director of the Vancouver Hospital and Health Sciences Centre’s Department of Psychiatry, and a practicing psychiatrist at the Vancouver General Hospital Gender Clinic. This clinician made the point that regardless of the sex organs present, it is "the programming of the brain which determines gender identity [which is] manifested only by three to four." It was argued that when gender dysphoria is present, there is both a medical need to address it, and precedent for doing so in a penal context. Where Kavanagh’s estrogen therapy was concerned, the psychiatrist found that as Kavanagh had been being treated for her dysphoria since she was 14 (a treatment that was discontinued only with her being served a life sentence), continuing to deprive her of this medication would be detrimental to both her health and rehabilitation.

The endocrine systems between mammals and fish are similar, because of this Danio rerio are a popular lab choice. The Danio rerio, or zebrafish work well as a model organism, part of which can be attributed to the fact that researchers are able to study them starting from the embryo, as the embryo is nearly transparent. Additionally, zebrafish have DNA sex markers, this allows the biologists to individually assign sex to fish, this is particularly important when studying endocrine disruptors as the disruptors can affect how, among other things, the sex organs work, so if by chance there is sperm in the ovaries later on through the testing it can then be pinned to the chemical without the chance of it being a genetic abnormality since the sex was determined by the researcher. Besides zebrafish being readily available, and easy to study through their different life stages, they have hugely similar genes to humans - 70% of human genes have a zebrafish counterpart and even more fascinatingly 84% of disease genes in humans have a zebrafish counterpart.

Evidence of pubic hair removal in ancient India is thought to date back to 4000 to 3000 BC. According to ethnologist F. Fawcett, writing in 1901, he had observed the removal of body hair, including pubic hair about the vulva, as a custom of women from the Hindu Nair caste. In Western societies, after the spread of Christianity, public exposure of a woman's bare skin between the ankle and waist started to be disapproved of culturally. Upper body exposure due to the use of the popular vest bodices used in Western Europe from the 15th century to early 20th century, as the widespread dirndls used even in more traditionally conservative mountain areas and the more or less loose shirts under these, enabled a permissive view of the shoulders, décolletage and arms allowing a free exposure of upper body hair in women of all classes with less rejection or discrimination than body hair on the sex organs, obviously to conceal by implication. Many people came to consider public exposure of pubic hair to be embarrassing.

Bogza was the subject of a portrait painted by his friend Victor Brauner, which was itself the topic of scandal. The piece, defined by S. A. Mansbach as one of Brauner's "most fully realized Surrealist canvases of [the early 1930s]", depicted the subject nude, with a severed head and elongated sex organs (symbols which probably alluded to elements present in Bogza's own texts). Bogza's novella, Sfârșitul lui Iacob Onisia ("The End of Iacob Onisia"), has served as the basis for a 1988 film, Iacob (translated into English as Jacob, or, in full, The Miseries of a Gold Miner – Jacob).Vincent Canby, "Review/Film; At Work and Home, a Difficult Life", in The New York Times, October 3, 1988 Doinel Tronaru, "Iacob Onisia se pregătește să moară", originally published in România Liberă (February 2003); at the LiterNet Publishing House; retrieved November 21, 2007 A story of violent workers leading miserable lives and tempted to steal for their livelihood, it was adapted for the screen and directed by Mircea Danieliuc, and starred Dorel Vișan in the title role (other actors credited include Cecilia Bîrbora, Ion Fiscuteanu and Dinu Apetrei).
