|
The spermatic ducts are then put back into the scrotum and the inner and outer dermal layers are sealed – then you can head home.
|
|
Justin "WebMD'd himself" into a tizzy and believed he had testicular torsion, a serious condition caused when a spermatic cord becomes twisted cutting off the flow of blood to the attached testicle.
|
|
According to their website, the device is surgically inserted into the spermatic ducts, which are transected using an electric scalpel while your boyfriend is locally anesthetized, so you two can still make out while he gets his cum button installed.
|
|
The device is designed to be inserted under local anesthesia in a half-hour long procedure, according to the company's website: Each spermatic duct is transected, then the newly cut ends are connected to the valve casing using specially developed instruments.
|
|
The spermatic plexus (or testicular plexus) is derived from the renal plexus, receiving branches from the aortic plexus. It accompanies the internal spermatic artery to the testis.
|
|
The internal spermatic fascia (infundibuliform fascia) (Le deuxième fascia de Webster) is a thin layer, which loosely invests the spermatic cord; it is a continuation downward of the transverse fascia.
|
|
The white flesh smells spermatic, but the scent is not distinctive.
|
|
The cremaster muscle is a muscle that covers the testis and the spermatic cord.
|
|
It is incised along its fibres and the spermatic cord is identified and isolated. From there, the testicle is pulled into the field through the inguinal canal. The spermatic cord is clamped off in two places and cut between the clamps. Long permanent sutures, usually silk or polypropylene, are left on the stump of the spermatic cord as a marker in case it needs to be removed in the future during a retroperitoneal lymph node dissection (RPLND).
|
|
The spermatic cord in the male and the round ligament of the uterus in the female pass through the transverse fascia at the deep inguinal ring the entrance to the inguinal canal. This opening is not visible externally. In the male the transverse fascia extends downwards as the internal spermatic fascia.
|
|
The external spermatic fascia (intercrural or intercolumnar fascia) is a thin membrane, prolonged downward around the surface of the spermatic cord and testis. It is separated from the dartos tunic by loose areolar tissue. It is occasionally referred to as 'Le Fascia de Webster' after an anatomist who once described it. It is derived from the aponeurosis of the abdominal external oblique muscle.
|
|
The spermatic cord is sensitive to torsion, in which the testicle rotates within its sac and blocks its own blood supply. Testicular torsion may result in irreversible damage to the testicle within hours. A collection of serous fluid in the spermatic cord is named 'funiculocele'. The contents of the abdominal cavity may protrude into the inguinal canal, producing an indirect inguinal hernia.
|
|
Varicose veins of the spermatic cord are referred to as varicocele. Though often asymptomatic, about one in four people with varicocele have negatively affected fertility.
|
|
Wide distribution Nothocybe The lamellae has not pleurocystidia but has cheilocystidia. Spores smooth. Known from tropical India. Pseudosperma Fruitbodies has indistinct, spermatic or green corn odor.
|
|
The internal spermatic artery supplies one or two small branches to the ureter, and in the inguinal canal gives one or two twigs to the Cremaster.
|
|
The vesical nervous plexus arises from the forepart of the pelvic plexus. The nerves composing it are numerous, and contain a large proportion of spinal nerve fibers. They accompany the vesicle arteries, and are distributed to the sides and fundus of the bladder. Numerous filaments also pass to the seminal vesicles and vas deferens; those accompanying the vas deferens join, on the spermatic cord, with branches from the spermatic plexus.

|
As they pass across the subcutaneous inguinal ring, they are connected together by delicate fibrous tissue, forming a fascia, called the intercrural fascia. This intercrural fascia is continued down as a tubular prolongation around the spermatic cord and testis, and encloses them in a sheath; hence it is also called the external spermatic fascia. The subcutaneous inguinal ring is seen as a distinct aperture only after the intercrural fascia has been removed.
|
|
He is remembered for his research on diseases of the testicles, spermatic cord and scrotum, and their effect on fertility and virility. In this regard he is considered a pioneer of andrology.
|
|
The vas deferens, as it leaves the spermatic cord in the male, and the round ligament of the uterus in the female, winds around the lateral and posterior aspects of the artery.
|
|
Two emasculators of different sizes. An emasculator is a tool used in the castration of livestock. Its function is to simultaneously crush and cut the spermatic cord, preventing hemorrhaging while still detaching the testis from the animal. The blade is always on the side of the emasculator with the nut that holds the blades in place, and should always be placed adjacent to the testis ("nut against nut") so that the crushing clamp occludes the spermatic artery, preventing life-threatening blood loss.
|
|
The mushroom also has a spermatic odour that is especially noticeable when the mushroom is damaged or crushed. Like many other Inocybe mushrooms, Inocybe hystrix contains dangerous amounts of muscarine and should not be consumed.
|
|
Complications from this procedure include bleeding and infection. The ilioinguinal nerve which runs anterior to the spermatic cord may be damaged during the operation and cause numbness over the inner thigh or chronic groin and scrotal pain. Other symptoms also include intermittent and chronic back pain and sudden loss of mobility in the lower back. If the orchiectomy is performed to diagnose cancer, the testicle and spermatic cord are then sent to a pathologist to determine the makeup of the tumor, and the extent of spread within the testicle and cord.
|
|
Inguinal orchiectomy (named from the Latin inguen for "groin," and also called radical orchiectomy), is performed when an onset of testicular cancer is suspected, in order to prevent a possible spread of cancer from the spermatic cord into the lymph nodes near the kidneys. An inguinal orchiectomy can be either unilateral or bilateral. The surgeon makes an incision in the patient's groin area (in contrast to an incision in the scrotum, as is done in both simple and subcapsular orchiectomies). The entire spermatic cord is removed, as well as the testicle(s).
|
|
The silk glove-sign is a diagnostic measure when a hernia or hydrocele is suspected, however, there is no other clinical evidence to prove their existence. It involves rolling of the spermatic cord which causes a feeling of pieces of silk friction. Positive sign demonstrates thickening of the spermatic cord, representing the hernial sac, in comparison with that on the other side. In fact, it is due to the thickening or silkiness of the cord as it crosses the pubic tubercle or, in the female, silkiness of the processus vaginalis over the pubic tubercle.
|
|
Specialized anatomic arrangements consist of two zones of coiling along the internal spermatic artery. This anatomic arrangement prolongs the time of contact and the thermal exchange between the testicular arterial and venous blood streams and may, in part, explain the temperature gradient between aortic and testicular arterial blood reported in dogs and rams. Moreover, reduction in pulse pressure, occurring in the proximal one third of the coiled length of the internal spermatic artery. Moreover, the activity of spermatogenic recombinase decreases, and this is supposed to be an important factor of testicles degeneration.
|
|
In human males, the cremaster muscle is a thin layer of striated muscle found in the inguinal canal and scrotum between the external and internal layers of spermatic fascia, surrounding the testis and spermatic cord. The cremaster muscle is a paired structure, there being one on each side of the body. Anatomically, the lateral cremaster muscle originates from the internal oblique muscle, just superior to the inguinal canal, and the middle of the inguinal ligament. The medial cremaster muscle, which sometimes is absent, originates from the pubic tubercle and sometimes the lateral pubic crest.
|
|
Buck's fascia is continuous with the external spermatic fascia in the scrotum and the suspensory ligament of the penis. On its ventral aspect, it splits to envelop corpus spongiosum in a separate compartment from the tunica albuginea and corporal bodies.
|
|
While the risks of blood loss and infection are low, anesthesia is, however necessary, as the burdizzo causes blunt force trauma to the spermatic cords, which are thickly wrapped in nerve fibres. So therefore, human use is disadvantageous as it may involve testicular infections.
|
|
The testicular vein (or spermatic vein), the male gonadal vein, carries deoxygenated blood from its corresponding testis to the inferior vena cava or one of its tributaries. It is the male equivalent of the ovarian vein, and is the venous counterpart of the testicular artery.
|
|
Inocybe lacera has mild-tasting flesh and a mild, mealy smell. The North American variety I. lacera var. heterosperma has a spermatic smell. However, species of Inocybe should always be avoided when choosing mushrooms for consumption, as many of the members of the genus are dangerously toxic.
|
|
Chimney sweeps' carcinoma is a squamous cell carcinoma of the skin of the scrotum. Warts caused by the irritation from soot particles, if not excised, developed into a scrotal cancer. This then invaded the dartos, enlarged the testicle, and proceeded up the spermatic cord into the abdomen where it proved fatal.
|
|
The crowded gills are adnexed and cream early, before darkening to a brownish colour with the developing spores. The spore print is brown. The almond-shaped spores are smooth and measure around 9 × 5 μm. The faint smell has been likened to meal, damp earth, or even described as spermatic.
|
|
Fruit bodies have convex to plano-convex caps measuring in diameter. The caps are dry with scales that can be either erect or flat on the surface. The colour is brown in the centre, becoming paler towards the edges. The flesh is white, and has a spermatic odour and mild taste.
|
|
The inguinal canals are the two passages in the anterior abdominal wall of humans and animals which in males convey the spermatic cords and in females the round ligament of the uterus. The inguinal canals are larger and more prominent in males. There is one inguinal canal on each side of the midline.
|
|
Sperm is formed in spermatic cysts and is free spawned into the surrounding water. Sperm is captured by females and is transported to oocytes within the sponge where fertilization takes place. The occurrence of sexual reproduction peaks from October to November. There is no relationship between age and reproductive ability in S. officinalis.
|
|
The genital branch of the genitofemoral nerve, also known as the external spermatic nerve in males, is a nerve in the abdomen that arises from the genitofemoral nerve. The genital branch supplies the cremaster muscle and anterior scrotal skin in males, and the skin of the mons pubis and labia majora in females.
|
|
The ratchet (visible on the handle) allows the emasculator to be locked in the "closed" position for the 2–3 minutes required for primary hemostasis to occur. The ends of the "clamp" are rounded and guarded to allow the emasculator to be placed over the testis and spermatic cord without cutting, until pressure is applied.
|
|
The pampiniform plexus (from Latin pampinus, a tendril, + forma, form) is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
|
|
In August 1971, a 9-year-old V-61 had a hematoma of the spermatic vessel. Minick took the bull to see Dr. W.A. Aanes at Colorado State University in Fort Collins, Colorado. They operated on the bull, and the surgery went well despite concerns about its potential hazards. V-61 became a popular patient during his stay.
|
|
The nurse will shave a small area for the incision. After anesthetic has been administered, the surgeon makes an incision in the midpoint of the scrotum and cuts through the underlying tissue. The surgeon removes the testicles and parts of the spermatic cord through the incision. The incision is closed with two layers of sutures and covered with a surgical dressing.
|
|
A long, non-absorbable suture may be left in the stump of the spermatic cord in case later surgery is deemed necessary. After the cord and testicle(s) have been removed, the surgeon washes the area with saline solution and closes the various layers of tissues and skin with various types of sutures. The wound is then covered with sterile gauze and bandaged.
|
|
The testicles lack anatomical protection and are highly sensitive to impact. The pain caused by impact to the testicles travels through the spermatic plexus. In extreme cases, a hard strike to the testicles can cause one or both to rupture, potentially sterilizing the victim. While less often depicted in media, a strike to the groin can cause pain for female victims too.
|
|
A varicocele is an abnormal enlargement of the pampiniform venous plexus in the scrotum. This plexus of veins drains blood from the testicles back to the heart. The vessels originate in the abdomen and course down through the inguinal canal as part of the spermatic cord on their way to the testis. Varicoceles occur in around 15% to 20% of all men.
|
|
It carries with it the ductus deference, that is testicular vessels and nerves, a portion of the abdominal muscle, and lymph vessels. All of the structures remain attached to the testis and form what is known as the spermatic cord by the time the testis is in the scrotal sac, the gubernaculum is no more than a remnant of scar like tissue.

|
He also performed the first successful thumb replacement, an operation involving replacement of a boy's lost thumb with the second toe of his right foot.Nicoladoni's operation @ Who Named It Nicoladoni made contributions in regards to urogenital and gastrointestinal surgery. He introduced new surgical techniques for treatment of esophageal diverticulum as well as for torsion of the spermatic cord. He also investigated the possibilities of gastroenterostomic surgery.
|
|
There are two ducts, connecting the left and right epididymis with the seminal vesicles to form the ejaculatory duct in order to move sperm. In humans, each tube is about long, 3 to 5 mm (0.118 to 0.197 inches) in diameter and is muscular (surrounded by smooth muscle). Its epithelium is pseudostratified columnar epithelium lined by stereocilia. They are part of the spermatic cords.
|
|
One study reported that denervation of the spermatic cord provided complete relief at the first follow-up visit in 13 of 17 cases, and that the other four patients reported improvement. As nerves may regrow, long-term studies are needed. One study found that epididymectomy provided relief for 50% of patients with post-vasectomy pain syndrome. Orchiectomy is recommended usually only after other surgeries have failed.
|
|
An angiomyolipoma is composed of varying proportions of vascular cells, immature smooth muscle cells, and fat cells. These three components respectively give rise to the components of the name: angio-, myo-, and lip-. The -oma suffix indicates a tumour. Angiomyolipomas are typically found in the kidney, but have also been commonly found in the liver and less commonly the ovary, fallopian tube, spermatic cord, palate, and colon.
|
|
Intratesticular masses that appear suspicious on an ultrasound should be treated with an inguinal orchiectomy. The pathology of the removed testicle and spermatic cord indicate the presence of the seminoma and assist in the staging. Tumors with both seminoma and nonseminoma elements or that occur with the presence of AFP should be treated as nonseminomas. Abdominal CT or MRI scans as well as chest imaging are done to detect for metastasis.
|
|
Boreoeutherian land mammals, the large group of mammals that includes humans, have externalized testes. Their testes function best at temperatures lower than their core body temperature. Their testes are located outside of the body, suspended by the spermatic cord within the scrotum. There are several hypotheses why most boreotherian mammals have external testes which operate best at a temperature that is slightly less than the core body temperature, e.g.
|

Fruit bodies have caps that are initially convex before flattening out, sometimes developing a slight umbo, and typically attain a diameter of . The cap surface is moist, smooth or somewhat covered in tiny scales, and violet in color. The flesh is white to yellowish white, with a mild taste and odor ranging from sour to radish-like to spermatic. Gill attachment ranges from adnexed to emarginate to free.
|
|
The subcardinals become the part of the posterior vena cava between the hepatic vein and the renal veins, and other portions become the internal gonadal (spermatic or ovarian) veins, and the suprarenal veins. The posterior cardinal veins become the veins of the pelvis, tail, and hind legs, and the part of the azygos vein that is closest to the heart.Romer, Alfred Sherwood (1989). The Vertebrate Body, p. 474.
|
|
The testicles converge to form the seminiferous tubules, coiled tubes at the top and back of each testicle. The second part of the duct system is the vas deferens, a muscular tube that begins at the lower end of the epididymis. The vas deferens passes upward along the side of the testicles to become part of the spermatic cord. The expanded end is the ampulla, which stores sperm before ejaculation.
|
|
The individual exhibits fever, chills, skin infections, painful lymph nodes, and tender skin of the lymphedematous extremity. These symptoms often lessen after 5–7 days. Other symptoms that may occur include orchitis, an inflammation of the testes, which is accompanied by painful, immediate enlargement and epididymitis (inflammation of the spermatic cord). #The obstructive (chronic) phase is marked by lymph varices, lymph scrotum, hydrocele, chyluria (lymph in urine), and elephantiasis.
|
|
Partial resection of the hydrocele sac, leaving a margin of 1–2 cm. Care is taken not to injure testicular vessels, epididymis or ductus deferens. The edge of the hydrocele sac is oversewn for hemostasis (von Bergmann's technique) or the edges are sewn together behind the spermatic cord (Winkelmann's or Jaboulay's technique). Hydrocele surgery with excision of the hydrocele sac is useful for large or thick-walled hydroceles and multilocular hydroceles.

Blafards were imagined to be "caused by a deficiency 'in their parents' spermatic liquor'" and were "absolutely deprived of the power of generation, or did not engender children that resemble them".Roger 2002. 21. Blafards were a manifestation of the early Anti-Americanism that originated in Europe in the 18th century. Their earliest mention is in the works of Georges-Louis Leclerc, Comte de Buffon and Cornelius De Pauw.

The scrotum is an anatomical male reproductive structure located caudal to the penis that consists of a suspended dual-chambered sack of skin and smooth muscle. It is present in most terrestrial male mammals. The scrotum contains the external spermatic fascia, testes, epididymis, and ductus deferens. It is a distention of the perineum and carries some abdominal tissues into its cavity including the testicular artery, testicular vein, and pampiniform plexus.
|
|
The femoral canal is conical and measures about 1.25 cm. in length. Its base, directed upward and named the femoral ring, is oval in form, its long diameter being directed transversely and measuring about 1.25 cm. The spermatic cord in the male and the round ligament of the uterus in the female lie immediately above the anterior margin of the ring, while the inferior epigastric vessels are close to its upper and lateral angle.
|
|
Most sponges are hermaphrodites (function as both sexes simultaneously), although sponges have no gonads (reproductive organs). Sperm are produced by choanocytes or entire choanocyte chambers that sink into the mesohyl and form spermatic cysts while eggs are formed by transformation of archeocytes, or of choanocytes in some species. Each egg generally acquires a yolk by consuming "nurse cells". During spawning, sperm burst out of their cysts and are expelled via the osculum.
|
|
The testicular artery (the male gonadal artery, also called the internal spermatic arteries in older texts) is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each of the testes. It is the male equivalent of the ovarian artery. Because the testis is found in a different location than that of its female equivalent, it has a different course than the ovarian artery.
|
|
The genital branch of the genitofemoral nerve arises from the ventral primary divisions of L1-L2 spinal nerve roots. It passes outward on the psoas major muscle, and pierces the fascia transversalis, or passes through the deep inguinal ring. It then descends within the spermatic cord. In males, it passes through to the scrotum, where it supplies the cremaster, dartos muscle and gives a few filaments to the skin of the scrotum.
|
|
Local anaesthetic is injected into the parenchyma of both testes. An incision is made through the scrotum and the testes are removed, then the spermatic cord is crushed, most commonly with either ligatures or emasculators, or both. The emasculators are applied for two to three minutes, then removed, and a careful check is made for signs of haemorrhage. Assuming that bleeding is at a minimum, the other side is castrated in the same manner.
|
|
The sigmoid arteries, two or three in number, run obliquely downward and to the left behind the peritoneum and in front of the psoas major, ureter, and internal spermatic vessels. They originate from the inferior mesenteric artery branch of the abdominal aorta. Their branches supply the lower part of the descending colon, the iliac colon, and the sigmoid or pelvic colon; anastomosing above with the left colic, and below with the superior hemorrhoidal artery.
|
|
Inguinal orchiectomy (also named orchidectomy) is a specific method of orchiectomy whereby one or both testicles and the full spermatic cord are surgically removed through an incision in the lower lateral abdomen (the "inguinal region"). The procedure is generally performed by a urologist, typically if testicular cancer is suspected. Often it is performed as same-day surgery, with the patient returning home within hours of the procedure. Some patients elect to have a prosthetic testicle inserted into their scrotum.
|
|
The superficial inguinal ring. The superficial inguinal ring (subcutaneous inguinal ring or external inguinal ring) is an anatomical structure in the anterior wall of the mammalian abdomen. It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve, the genital branch of the genitofemoral nerve, and the spermatic cord (in men) or the round ligament (in women). At the other end of the canal, the deep inguinal ring forms the entrance.
|
|
The reflected inguinal ligament (triangular fascia) is a layer of tendinous fibers of a triangular shape, formed by an expansion from the lacunar ligament and the inferior crus of the subcutaneous inguinal ring. It passes medialward behind the spermatic cord, and expands into a somewhat fan-shaped band, lying behind the superior crus of the subcutaneous inguinal ring, and in front of the inguinal aponeurotic falx, and interlaces with the ligament of the other side of the linea alba.
|
|
The initial incision was extended along the raphe of the scrotum to the root of the penis. The surgical field was widened by retracting the scrotal skin on both sides and widely exposing the corpus spongiosum, both corpora cavernosa, and the two testes. Once the testes and their pedicles had been dissected, the spermatic cord was cut and ligated. Then, both corpora cavernosa were ligated and cut at a level just distally to their attachment to the inferior ramus of the pubic bone.

|
The C. adunca hatchling develops multiple embryonic kidneys, where other Crepidula only develop one, meaning it is a direct developer and also cannot develop the operculum. For Crepidula species, the phallus of the organism usually becomes reaches full size when there is enough sperm to fill the spermatic vesicles, then it begins to outgrow its juvenile shell. However C. adunca is an exception, where the phallus immediately begins growth at the time of hatching. C. adunca broods to reproduce, all year.

|
The plateau phase is the precursor to orgasm, which may be mostly biological for men and mostly psychological for women. Orgasm is the release of tension, and the resolution period is the unaroused state before the cycle begins again. The male sexual response cycle starts in the excitement phase; two centers in the spine are responsible for erections. Vasoconstriction in the penis begins, the heart rate increases, the scrotum thickens, the spermatic cord shortens, and the testicles become engorged with blood.
|
|
The abdominal aortic plexus (not to be confused with the thoracic aortic plexus) is formed by branches derived, on either side, from the celiac plexus and ganglia, and receives filaments from some of the lumbar ganglia. It is situated upon the sides and front of the aorta, between the origins of the superior and inferior mesenteric arteries. From this plexus arise part of the spermatic, the inferior mesenteric, and the hypogastric plexuses; it also distributes filaments to the inferior vena cava.
|
|
The renal plexus is formed by filaments from the celiac ganglia and plexus, aorticorenal ganglia, lower thoracic splanchnic nerves and first lumbar splanchnic nerve and aortic plexus. The nerves from these sources, fifteen or twenty in number, have a few ganglia developed upon them. It enters the kidneys on arterial branches to supply the vessels, Renal glomerulus, and tubules with branches to the ureteric plexus. Some filaments are distributed to the spermatic plexus and, on the right side, to the inferior vena cava.
|
|
Usually, the patient disrobes completely and puts on a gown. The physician, physician assistant, or nurse practitioner will perform a thorough examination of the penis, scrotum, testicles, I vas deferens, spermatic cords, ejaculatory ducts, urethra, urinary bladder, anus and rectum. An orchidometer can measure testicular volume, which in turn is tightly associated with both sperm and hormonal parameters. A physical exam of the scrotum can reveal a varicocele, but the impact of detecting and surgically correct a varicocele on sperm parameters or overall male fertility is debated.
|
|
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum during its descent it carries along with it vas deferens, its vessels, nerves etc. There is one on each side.
|
|
Cells called the Leydig cells lie between the tubules; these produce hormones called androgens; these consist of testosterone and inhibin. The testicles are held by the spermatic cord, which is a tubelike structure containing blood vessels, nerves, the vas deferens, and a muscle that helps to raise and lower the testicles in response to temperature changes and sexual arousal, in which the testicles are drawn closer to the body. Sperm gets transported through a four- part duct system. The first part of this system is the epididymis.
|
|
Microsurgery has been used to treat several pathologic conditions leading to infertility such as tubal obstructions, vas deferens obstructions and varicocele which is one of the most frequent cause of male infertility. Microsurgical drainages by placing micro vascular bypasses between spermatic and inferior epigastric veins as proposed by Flati et al. have been successfully performed in treating male infertility due to varicocele. Microsurgical treatment has been shown to significantly improve fertility rate also in patients with recurrent varicocele who had previously undergone non microsurgical treatments.
|
|
Orchitis can be related to epididymitis infection that has spread to the testicles (then called "epididymo-orchitis"), sometimes caused by the sexually transmitted diseases chlamydia and gonorrhea. It has also been reported in cases of males infected with brucellosis.Brucellosis in Humans and Animals World Health Organization Publication number WHO/CDS/EPR/2006.7 Orchitis can also be seen during active mumps, particularly in adolescent boys. Ischemic orchitis may result from damage to the blood vessels of the spermatic cord during inguinal herniorrhaphy, and may in the worst event lead to testicular atrophy.
|
|
A nine-inch Burdizzo, used primarily on goats, small calves, and sometimes on humans. The Burdizzo is a castration device which employs a large clamp designed to break the blood vessels leading into the testicles. Once the blood supply to the testicles is lost, testicular necrosis occurs, and the testicles shrink, soften, and eventually deteriorate completely. When the device is used, the operator crushes the spermatic cords one at a time, leaving a space in between in order to prevent an interruption of blood-flow to the scrotum.
|
|
In the male the duct persists, and forms the tube of the epididymis, the vas deferens and the ejaculatory duct, while the seminal vesicle arises during the third month as a lateral diverticulum from its hinder end. A large part of the head end of the mesonephros atrophies and disappears; of the remainder the anterior tubules form the efferent ducts of the testicle; while the posterior tubules are represented by the ductuli aberrantes, and by the paradidymis, which is sometimes found in front of the spermatic cord above the head of the epididymis.

In 1937 he was finally appointed Fifth Surgeon at Colombo General Hospital. In 1937 he was appointed first professor of surgery at Ceylon Medical College, a position he held until his retirement. He continued to work at Colombo General Hospital and Lady Ridgeway Hospital for Children during that time. Paul was the first Ceylonese to deliver the Hunterian Oration at the Royal College of Surgeons of England on three occasions – The Surgical Anatomy of the Spermatic Cord (1950), Congenital Abnormalities of the Midline Abdominal Wall (1953) and Haemorrhages from Head Injuries (1955).

It was reported in 1775 by Sir Percival Pott in climbing boys or chimney sweepers. It is the first industrially related cancer to be found. Potts described it: > It is a disease which always makes it first attack on the inferior part of > the scrotum where it produces a superficial, painful ragged ill-looking sore > with hard rising edges…in no great length of time it pervades the skin, > dartos and the membranes of the scrotum, and seizes the testicle, which it > inlarges [sic], hardens and renders truly and thoroughly distempered. Whence > it makes its way up the spermatic process into the abdomen.

The transversalis fascia (or transverse fascia) is a thin aponeurotic membrane which lies between the inner surface of the transverse abdominal muscle and the parietal peritoneum. It forms part of the general layer of fascia lining the abdominal parietes, and is directly continuous with the iliac fascia, internal spermatic, and pelvic fasciae. In the inguinal region, the transversalis fascia is thick and dense in structure and is joined by fibers from the aponeurosis of the transverse abdominal. It becomes thin as it ascends to the diaphragm and blends with the fascia covering the under surface of this muscle.
|
|
It is of an oval form, the long axis of the oval being vertical; it varies in size in different subjects, and is much larger in the male than in the female. It is bounded, above and laterally, by the arched lower margin of the transversalis fascia; below and medially, by the inferior epigastric vessels. It transmits the spermatic cord in the male and the round ligament of the uterus in the female. From its circumference a thin funnel- shaped membrane, the infundibuliform fascia, is continued around the cord and testis, enclosing them in a distinct covering.
|
|
The veins of the plexus ascend along the spermatic cord in front of the vas deferens. Below the superficial inguinal ring they unite to form three or four veins, which pass along the inguinal canal, and, entering the abdomen through the deep inguinal ring, coalesce to form two veins. These again unite to form a single vein, the testicular vein, which opens on the right side into the inferior vena cava, at an acute angle, and on the left side into the left renal vein, at a right angle. The pampiniform plexus forms the chief mass of the cord.

Too-frequent ejaculation was thought to weaken men. Greek medical theories based on the classical elements and humors recommended limiting the production of semen by means of cooling, drying, and astringent therapies, including cold baths and the avoidance of flatulence-causing foods.Dugan, pp. 403–404. In the 2nd century AD, the medical writer Galen explains semen as a concoction of blood (conceived of as a humor) and pneuma (the "vital air" required by organs to function) formed within the man's coiled spermatic vessels, with the humor turning white through heat as it enters into the testicles.Dugan, pp. 404–405.

The more modern variety of truss is made with non- intrusive flat pads and comes with a guarantee to hold the hernia securely during all activities. Although there is as yet no proof that such devices can prevent an inguinal hernia from progressing, they have been described by users as providing greater confidence and comfort when carrying out physically demanding tasks. A truss also increases the probability of complications, which include strangulation of the hernia, atrophy of the spermatic cord, and atrophy of the fascial margins. This allows the defect to enlarge and makes subsequent repair more difficult.

The lower lateral limit is the anterior crest of the ilium and Poupart's ligament, which runs from the anterior superior spine of the ilium to the spine of the pubis. These lower limits are marked by visible grooves. Just above the pubic spines on either side are the external abdominal rings, which are openings in the muscular wall of the abdomen through which the spermatic cord emerges in the male, and through which an inguinal hernia may rupture. One method by which the location of the abdominal contents can be appreciated is to draw three horizontal and two vertical lines.

The development of intracytoplasmic sperm injection made conception a possibility for patients with a variety of male infertility conditions, including globozoospermia. However, fertility rates with this approach are still low, and research is ongoing into how this can be improved. It has been found that treating globozoospermia with ICSI along with oocyte activation by calcium ionophore (an ion carrier used to increase intracellular calcium is more likely to result in conception than ICSI alone. Another promising treatment area also looks at causing oocyte activation in conjunction with ICSI, this time using spermatic binding-proteins, phospholipase C zeta (PLCζ) and postacrosomal sheath WW domain binding protein (PAWP).

The term paradidymis (organ of Giraldés) is applied to a small collection of convoluted tubules, situated in front of the lower part of the spermatic cord, above the head of the epididymis. These tubes are lined with columnar ciliated epithelium, and probably represent the remains of a part of the Wolffian body, like the epididymis, but are functionless and vestigial. The Wolffian body operates as a kidney (mesonephros) in fishes and amphibians, but the corresponding tissue is co-opted to form parts of the male reproductive system in other classes of vertebrate. The paradidymis represents a remnant of an unused, atrophied part of the Wolffian body.

To castrate (medical term: orchiectomy) is to remove the testicles of a male animal. Different techniques are used depending on the type of animal, including ligation of the spermatic cord with suture material, placing a rubber band around the cord to restrict blood flow to the testes, or crushing the cord with a specialized instrument like the Burdizzo. Pyometra surgery Neutering is usually performed to prevent breeding, prevent unwanted behavior, or decrease risk of future medical problems. Neutering is also performed as an emergency procedure to treat certain reproductive diseases, like pyometra and testicular torsion, and it is used to treat ovarian, uterine, and testicular cancer.

The dartos fascia or simply dartos is a layer of connective tissue found in the penile shaft, foreskin, and scrotum. The penile portion is referred to as the superficial fascia of penis or the subcutaneous tissue of penis,Terminologica Anatomica 98 while the scrotal part is the dartos proper. In addition to being continuous with itself between the scrotum and the penis, it is also continuous with Colles fascia of the perineum and Scarpa's fascia of the abdomen. It lies just below the skin, which places it just superficial to the external spermatic fascia in the scrotum and to Buck's fascia in the penile shaft.

The tunica albuginea is the fibrous covering of the testis. It is a dense blue-grey membrane, composed of bundles of white fibrous connective tissue, from which it derives its name albuginea, which interlace in every direction. The tunica albuginea is covered by the tunica vaginalis, except at the points of attachment of the epididymis to the testis, and along its posterior border, where the spermatic vessels enter the gland. The tunica albuginea is applied to the tunica vasculosa over the glandular substance of the testis, and, at its posterior border, is reflected into the interior of the gland, forming an incomplete vertical septum, called the mediastinum testis (corpus Highmori).

Also, in the inguinal crest a structure, the gubernaculum testis, makes its appearance. This is at first a slender band, extending from that part of the skin of the groin which afterward forms the scrotum through the inguinal canal to the body and epididymis of the testis. As development advances, the peritoneum enclosing the gubernaculum forms two folds, one above the testis and the other below it. The one above the testis is the plica vascularis, and contains the upper part of the gubernaculum, and ultimately also the internal spermatic vessels; the one below, the plica gubernatrix, contains the lower part of the gubernaculum.

The machine had a database of 10,000 similar operations, and so, in the words of its designers, was "more than qualified to operate on any patient". In August 2007, Dr. Sijo Parekattil of the Robotics Institute and Center for Urology (Winter Haven Hospital and University of Florida) performed the first robotic-assisted microsurgery procedure denervation of the spermatic cord for chronic testicular pain. In February 2008, Dr. Mohan S. Gundeti of the University of Chicago Comer Children's Hospital performed the first robotic pediatric neurogenic bladder reconstruction. On 12 May 2008, the first image-guided MR-compatible robotic neurosurgical procedure was performed at University of Calgary by Dr. Garnette Sutherland using the NeuroArm.

The left colic artery is a branch of the inferior mesenteric artery that runs to the left behind the peritoneum and in front of the psoas major muscle, and after a short, but variable, course divides into an ascending and a descending branch; the stem of the artery or its branches cross the left ureter and left internal spermatic vessels. The ascending branch crosses in front of the left kidney and ends, between the two layers of the transverse mesocolon, by anastomosing with the middle colic artery; the descending branch anastomoses with the highest sigmoid artery. From the arches formed by these anastomoses branches are distributed to the descending colon and the left part of the transverse colon.

A physician may diagnose an inguinal hernia, as well as the type, from medical history and physical examination. For confirmation or in uncertain cases, medical ultrasonography is the first choice of imaging, because it can both detect the hernia and evaluate its changes with for example pressure, standing and Valsalva maneuver. When assessed by ultrasound or cross sectional imaging with CT or MRI, the major differential in diagnosing indirect inguinal hernias is differentiation from spermatic cord lipomas, as both can contain only fat and extend along the inguinal canal into the scrotum. On axial CT, lipomas originate posterolateral to the cord, and are located inside the cremaster muscle, while inguinal hernias lie anteromedial to the cord and are not intramuscular.

It arises from the external iliac artery, immediately above the inguinal ligament. It curves forward in the subperitoneal tissue, and then ascends obliquely along the medial margin of the abdominal inguinal ring; continuing its course upward, it pierces the transversalis fascia, and, passing in front of the linea semicircularis, ascends between the Rectus abdominis and the posterior lamella of its sheath. It finally divides into numerous branches, which anastomose, above the umbilicus, with the superior epigastric branch of the internal thoracic artery and with the lower intercostal arteries. As the inferior epigastric artery passes obliquely upward from its origin it lies along the lower and medial margins of the abdominal inguinal ring, and behind the commencement of the spermatic cord.

This cancer was a manifestation of scrotal squamous cell carcinoma which had first been noted in 1775 by Sir Percival Pott in climbing boys or chimney sweepers. It was the first industrially related cancer to be identified and was originally called soot wart, then chimney sweeps cancer. He describes it: > It is a disease which always makes it first attack on the inferior part of > the scrotum where it produces a superficial, painful ragged ill-looking sore > with hard rising edges ... in no great length of time it pervades the skin, > dartos and the membranes of the scrotum, and seizes the testicle, which it > inlarges, hardens and renders truly and thoroughly distempered. Whence it > makes its way up the spermatic process into the abdomen.

Nicholas Chare, in an article titled "Sexing the Canvas", has linked Pricasso's work with statements by classic modern painters who referred to the activity of painting as a "seminal" or "spermatic" activity with sexual connotations. In the lead-up to the 2008 Sexpo in Cape Town, Pricasso published a video online showing him creating a painting of then-Mayor of Cape Town Helen Zille. Although he stated the painting was not meant to insult or embarrass Zille, The Times reported that two art galleries in Johannesburg declined to associate themselves with Pricasso's artwork. The curator of Moja Modern gallery suggested that the ridicule of his work could abate in fifty years time and his painting seen as having broken boundaries in art.

The right colic artery arises from about the middle of the concavity of the superior mesenteric artery, or from a stem common to it and the ileocolic. It passes to the right behind the peritoneum, and in front of the right internal spermatic or ovarian vessels, the right ureter and the Psoas major, toward the middle of the ascending colon; sometimes the vessel lies at a higher level, and crosses the descending part of the duodenum and the lower end of the right kidney. At the colon it divides into a descending branch, which anastomoses with the ileocolic, and an ascending branch, which anastomoses with the middle colic. These branches form arches, from the convexity of which vessels are distributed to the ascending colon.

The part of the Y-chromosome which is responsible for maleness is the sex-determining region of the Y-chromosome, the SRY. The SRY activates Sox9, which forms feedforward loops with FGF9 and PGD2 in the gonads, allowing the levels of these genes to stay high enough in order to cause male development; for example, Fgf9 is responsible for development of the spermatic cords and the multiplication of Sertoli cells, both of which are crucial to male sexual development. The ZW sex-determination system, where males have a ZZ (as opposed to ZW) sex chromosome may be found in birds and some insects (mostly butterflies and moths) and other organisms. Members of the insect order Hymenoptera, such as ants and bees, are often determined by haplodiploidy, where most males are haploid and females and some sterile males are diploid.

Pott's early investigations contributed to the science of epidemiology and the Chimney Sweepers Act 1788. Pott describes chimney sweeps' carcinoma thus: > It is a disease which always makes it first attack on the inferior part of > the scrotum where it produces a superficial, painful ragged ill-looking sore > with hard rising edges.....in no great length of time it pervades the skin, > dartos and the membranes of the scrotum, and seizes the testicle, which it > inlarges, hardens and renders truly and thoroughly distempered. Whence it > makes its way up the spermatic process into the abdomen. He comments on the life of the boys: > The fate of these people seems peculiarly hard ... they are treated with > great brutality ... they are thrust up narrow and sometimes hot chimnies, > where they are bruised burned and almost suffocated; and when they get to > puberty they become ... liable to a most noisome, painful and fatal disease.

When it comes to the treatment of urinary tract stones, many solutions were suggested, including drinking a lot of a water/wine mixture, taking strong medication, or trying different positions when trying to flush them out. Extracting the urinary tract stones was another option; however, this method was not utilized very often due to its serious risks and possible complications of cutting into the bladder. Other than leakage of urine into the body cavity, another common complication was that of the cells of the testes dying due to the spermatic cord inadvertently being cut during the procedure. In fact, due to these and other complications and the lack of antiseptics and pain medicines, the Hippocratic Oath opted for the avoidance of surgery – unless absolutely necessary – especially when concerning surgeries that dealt with the urinary tract and more so when stone removal was the intent.

They are two slender vessels of considerable length, and arise from the front of the aorta a little below the renal arteries. Each passes obliquely downward and lateralward behind the peritoneum, resting on the Psoas major, the right lying in front of the inferior vena cava and behind the middle colic and ileocolic arteries and the terminal part of the ileum, the left behind the left colic and sigmoid arteries and the iliac colon. Each crosses obliquely over the ureter and the lower part of the external iliac artery to reach the abdominal inguinal ring, through which it passes, and accompanies the other constituents of the spermatic cord along the inguinal canal to the scrotum, where it becomes tortuous, and divides into several branches. Two or three of these accompany the ductus deferens, and supply the epididymis, anastomosing with the artery of the ductus deferens; others pierce the back part of the tunica albuginea, and supply the substance of the testis.

As the testes develops, the main portion of the lower end of the gubernaculum is carried, following the skin to which it is attached, to the bottom of this pouch. Other bands are carried to the medial side of the thigh and to the perineum. The tube of peritoneum constituting the vaginal process projects itself downward into the inguinal canal, and emerges at the external inguinal ring, pushing before it a part of the obliquus internus and the aponeurosis of the obliquus externus, which form respectively the cremaster muscle and the external spermatic fascia. The vaginal process forms a gradually elongating pouch, which eventually reaches the bottom of the scrotum, and behind this pouch the testis is drawn by the growth of the body of the fetus, for the gubernaculum does not grow proportionately with the growth of other parts, and therefore the testis, being attached by the gubernaculum to the bottom of the scrotum, is prevented from rising as the body grows, and is instead drawn first into the inguinal canal and eventually into the scrotum.
