Until now no company has tried to wrap up the key four stages that really do ensure a woman's fertility: eggs and sperm freezing (in the case of couples) in the peak fertility years (20s-30s); embryo creation; genetic screening for inherited diseases and abnormalities; and the final stage of embryo transfer into the woman's body.
|
|
For women trying to get pregnant on their own, the most common fertility treatments are intrauterine insemination (IUI), a non-invasive procedure wherein donor sperm is placed in the uterus while a woman is ovulating, and in vitro fertilization (IVF), which involves removal and fertilization of a woman's eggs via donor sperm, followed by embryo transfer into her uterus.

It is uncertain whether the use of mechanical closure of the cervical canal following embryo transfer has any effect. Whether or not women remain laying down for a certain amount of time after embryo transfer may make little or no difference. Using hyaluronic acid as an adherence medium for the embryo may increase live birth rates. There may be little or benefit in having a full bladder, removal of cervical mucus, or flushing of the endometrial or endocervical cavity at the time of embryo transfer.

Biomarker in in vitro fertilization process PP-14 is known to be a great marker to predict the outcome of in vitro fertilization and the embryo transfer cycle. Some studies have shown that the serum concentration of Placental Protein 14 was highly increased after the embryo transfer cycle, and they conclude that PP-14 might be an excellent marker to predict the endometrial receptivity.

The duration of embryo culture can be varied, conferring different stages of embryogenesis at embryo transfer. The main stages at which embryo transfer is performed are cleavage stage (day 2 to 4 after co- incubation) or the blastocyst stage (day 5 or 6 after co-incubation). Embryos which reach the day 3 cell stage can be tested for chromosomal or specific genetic defects prior to possible transfer by preimplantation genetic diagnosis (PGD). Embryo culture until the blastocyst stage confers a significant increase in live birth rate per embryo transfer, and there is no evidence of a difference between the groups in cumulative pregnancy rates.
|
|
The usage of single embryo transfer is highest in Sweden (69.4%), but as low as 2.8% in the USA. Access to public funding for ART, availability of good cryopreservation facilities, effective education about the risks of multiple pregnancy, and legislation appear to be the most important factors for regional usage of single embryo transfer. Also, personal choice plays a significant role as many subfertile couples have a strong preference for twins.

Retrieved 21 October 2008. Embryo transfer is also used in laboratory mice. For example, embryos of genetically modified strains that are difficult to breed or expensive to maintain may be stored frozen, and only thawed and implanted into a pseudopregnant dam when needed. On February 19, 2020, the first pair of Cheetah cubs to be conceived through embryo transfer from a surrogate cheetah mother was born at Columbus Zoo in Ohio.

That is, the cumulative live birth rate associated with single fresh embryo transfer followed by a single frozen and thawed embryo transfer is comparable with that after one cycle of double fresh embryo transfer. Furthermore, SET has better outcomes in terms of mean gestational age at delivery, mode of delivery, birthweight, and risk of neonatal intensive care unit necessity than DET. e-SET of embryos at the cleavage stage reduces the likelihood of live birth by 38% and multiple birth by 94%. Evidence from randomized, controlled trials suggests that increasing the number of e-SET attempts (fresh and/or frozen) results in a cumulative live birth rate similar to that of DET.

In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI). In fact, pregnancy rates are increased following frozen embryo transfer, and perinatal outcomes are less affected, compared to embryo transfer in the same cycle as ovarian hyperstimulation was performed. The endometrium is believed to not be optimally prepared for implantation following ovarian hyperstimulation, and therefore frozen embryo transfer avails for a separate cycle to focus on optimizing the chances of successful implantation.

Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary. Embryo transfer can be done at day two or day three, or later in the blastocyst stage, which was first performed in 1984.
|
|
Breed registries also differ as to their acceptance or rejection of breeding technology. For example, all Jockey Club Thoroughbred registries require that a registered Thoroughbred be a product of a natural mating, so-called "live cover". A foal born of two Thoroughbred parents, but by means of artificial insemination or embryo transfer, cannot be registered in the Thoroughbred studbook. However, since the advent of DNA testing to verify parentage, most breed registries now allow artificial insemination, embryo transfer, or both.

Embryos can be either “fresh” from fertilized egg cells of the same menstrual cycle, or “frozen”, that is they have been generated in a preceding cycle and undergone embryo cryopreservation, and are thawed just prior to the transfer, which is then termed "frozen embryo transfer" (FET). The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI). In fact, pregnancy rates are increased following FET, and perinatal outcomes are less affected, compared to embryo transfer in the same cycle as ovarian hyperstimulation was performed. The endometrium is believed to not be optimally prepared for implantation following ovarian hyperstimulation, and therefore frozen embryo transfer avails for a separate cycle to focus on optimizing the chances of successful implantation.

Embryo transfer is usually performed on day three or day five post-fertilization, the timing depending on the techniques used for PGD and the standard procedures of the IVF centre where it is performed. With the introduction in Europe of the single-embryo transfer policy, which aims at the reduction of the incidence of multiple pregnancies after ART, usually one embryo or early blastocyst is replaced in the uterus. Serum hCG is determined at day 12. If a pregnancy is established, an ultrasound examination at 7 weeks is performed to confirm the presence of a fetal heartbeat.
|
|
The technique of selecting only one embryo to transfer to the woman is called elective-single embryo transfer (e-SET) or, when embryos are at the blastocyst stage, it can also be called elective single blastocyst transfer (eSBT). It significantly lowers the risk of multiple pregnancies, compared with e.g. Double Embryo Transfer (DET) or double blastocyst transfer (2BT), with a twinning rate of approximately 3.5% in sET compared with approximately 38% in DET, or 2% in eSBT compared with approximately 25% in 2BT. At the same time, pregnancy rates is not significantly less with eSBT than with 2BT.

This scientific breakthrough established standards and became an agent of change for women suffering from the afflictions of infertility and for women who did not want to pass on genetic disorders to their children. Donor embryo transfer has given women a mechanism to become pregnant and give birth to a child that will contain their husband's genetic makeup. Although donor embryo transfer as practiced today has evolved from the original non-surgical method, it now accounts for approximately 5% of in vitro fertilization recorded births. Prior to this, thousands of women who were infertile, had adoption as the only path to parenthood.

It is not necessary that the embryo transfer be performed on the female who provided the eggs. Thus another female whose uterus is appropriately prepared can receive the embryo and become pregnant. Embryo transfer may be used where a woman who has eggs but no uterus and wants to have a biological baby; she would require the help of a gestational carrier or surrogate to carry the pregnancy. Also, a woman who has no eggs but a uterus may utilize egg donor IVF, in which case another woman would provide eggs for fertilization and the resulting embryos are placed into the uterus of the patient.

The development of the Merino is entering a new phase: objective fleece measurement and BLUP is now being used to identify exceptional animals. Artificial insemination and embryo transfer are being used to accelerate the spread of their genes. The result is a wide outcrossing between all major strains.

Females are induced ovulators; the act of mating and the presence of semen causes them to ovulate. Females usually conceive after just one breeding, but occasionally do have trouble conceiving. Artificial insemination is technically difficult, expensive and not common, but it can be accomplished. Embryo transfer is more widespread.
|
|
During embryo transfer (ET) a minor surgical procedure with almost no risk of injury or infection when performed properly, sheep laparoscopy allows the importation of improved genetics, even of breeds which may otherwise be non-existent in certain countries due to the regulation of live animal imports. Embryo transfer procedures are used to allow producers to maximize those females that produce the best lambs/kids either for retention into the flock or for sale to other producers. ET also allows producers to continue to utilize a ewe/doe that may not physically be able to carry or feed a set of lambs. ET can allow a producer to grow his flock quickly with above average individuals of similar bloodlines.
|
|
Embryo transfer can be performed after various durations of embryo culture, conferring different stages in embryogenesis. The main stages at which embryo transfer is performed are cleavage stage (day 2 to 4 after co-incubation) or the blastocyst stage (day 5 or 6 after co-incubation). Embryos who reach the day 3 cell stage can be tested for chromosomal or specific genetic defects prior to possible transfer by preimplantation genetic diagnosis (PGD). Transferring at the blastocyst stage confers a significant increase in live birth rate per transfer, but also confers a decreased number of embryos available for transfer and embryo cryopreservation, so the cumulative clinical pregnancy rates are increased with cleavage stage transfer.

Estrus behaviour can be detected by an experienced stockman. These behaviours can include standing to be mounted, mounting other cows, restlessness, decreased milk production, and decreased feed intake. More recently, embryo transfer has been used to enable the multiplication of progeny from elite cows. Such cows are given hormone treatments to produce multiple embryos.

However, no data to date has proven this benefit in fetal development and birth of healthy offspring after embryo transfer to surrogate females. However, this protocol could potentially improve the quality of vitrified human oocytes and embryos during IVM. In a research by Wang X et al.

Unlike a significant number of registered breeds today, a horse cannot be registered as a Thoroughbred (with The Jockey Club registry) unless conceived by live cover, the witnessed natural mating of a mare and a stallion. Artificial insemination (AI) and embryo transfer (ET), though commonly used and allowable in many other horse breed registries, cannot be used with Thoroughbreds.

However, some fish do not fit these categories. The livebearing largespring gambusia (Gambusia geiseri) was thought to be ovoviviparous until it was shown in 2001 that the embryos received nutrients from the mother.Marsh-Matthews E, Skierkowski P and DeMarais A (2001) "Direct Evidence for Mother-to-Embryo Transfer of Nutrients in the Livebearing Fish Gambusia geiseri" Copeia, 2001: 1(1-6).

Buster and other members of the UCLA research team were featured in People Magazine, and Time Magazine. Building upon Buster's research, over 200,000 live births resulting from donor embryo transfer have been recorded by the Centers for Disease Control(CDC) in the United States. Buster continues to practice medicine as a reproductive endocrinologist at Women and Infants' Fertility Center in Providence, Rhode Island.

Transfer day 2 instead of day 3 after fertilization has no differences in live birth rate. Monozygotic twinning is not increased after blastocyst transfer compared with cleavage-stage embryo transfer. There are significantly higher odds of preterm birth (odds ratio 1.3) and congenital anomalies (odds ratio 1.3) among births from embryos cultured until the blastocyst stage compared with cleavage stage.

Women pregnant with twins or higher-order multiples are at higher risk for pregnancy complications. Routine bed rest in twin pregnancies (bed rest in the absence of complications) does not improve outcomes. Bed rest is therefore not recommended routinely in those with a multiple pregnancy. Use in combination with assisted reproductive technology such as embryo transfer is also not recommended.

Dr. Binoy Sebastian Vettical of Kerala Livestock Development Board Ltd has produced the embryo stored frozen in Ethylene Glycol freeze media by slow programmable freezing (SPF) technique and transferred directly to recipient cattle immediately after thawing the frozen straw in water for the birth of this calf. In a study, in vivo produced crossbred bovine embryos stored frozen in ethylene glycol freeze media were transferred directly to recipients under tropical conditions and achieved a pregnancy rate of 50 percent.Binoy Sebastian Vettical, Kuruvilla Varghese and K.Muraleedharan. Cryopreservation of Embryos in Ethylene Glycol Freeze Media and Direct Transfer in Crossbred Cattle in the Tropics, Compendium: 9th International Congress on Biotechnology in Animal Reproduction In a survey of the North American embryo transfer industry, embryo transfer success rates from direct transfer of embryos were as good as to those achieved with glycerol.

As the number of programs in the U.S. was still minuscule then, The Chicago Tribune dedicated a two-day series of articles to its opening. In 1982 was appointed as founding editor-in-chief of The Journal of In Vitro Fertilization and Embryo Transfer (JIVF-ET), holding this position for approximately 20 years. In 1991 Gleicher was awarded Austrian Decoration for Science and Art for his work.

Ratnam was also the visiting Professor in the UK in 1982 and South Africa in 1994. In 1987, he also pioneered the procedure of giving birth to a baby born from frozen embryo transfer. He was part of a team of clinicians and scientists which led to the world's first microinjection baby via human ampullary coculture in 1991. Ratnam also contributed to gynaecology through research.

Pregnancy is typically initiated by artificial insemination in the case of sperm donation and by embryo transfer after in vitro fertilisation (IVF) in the case of egg donation, embryo donation, and surrogacy. Thus a child can have a genetic and social (non-genetic, non- biological) father, and a genetic, gestational, and social (non-biological) mother, and any combinations thereof. Theoretically a child thus could have 5 parents.

General de Gaulle offered to the Sultan of Morocco Bois de Rose, a thoroughbred which had been stationed at the stud for two years. The stud then grew gradually in the field of reproduction, by investing in an artificial insemination centre, a centre for the freezing of semen and an embryo transfer unit. Thus, the electoral district of Saint-Lô has the highest density of breeding deposits of France.

One alternative is to use a GnRH agonist instead of hCG. While this has been repeatedly shown to "virtually eliminate" OHSS risk, there is some controversy regarding the effect on pregnancy rates if a fresh non-donor embryo transfer is attempted, almost certainly due to a luteal phase defect. There is no dispute that the GnRH agonist trigger is effective for oocyte donors and for embryo banking (cryopreservation) cycles.

During the 1990s, the charity funded research which discovered that ultrasound could be used to detect abnormalities in early pregnancy. This resulted in pre-natal screening for Down's Syndrome. The charity enabled breakthroughs in IVF, by funding research into the optimum time for embryo transfer, and by looking at how eggs mature in the ovary. This was described at the time as ‘the biggest advance in fertility treatment’.

CIDRs may be used as a treatment in cows with follicular cysts. Follicular cysts in cattle affect a significant proportion of dairy cows in several countries, and hinder the dairy industry by extending the period from calving to conception. CIDRs help by reducing the Luteinizing Hormone pulse frequency and inducing atresia of cystic follicles. This may also allow affected cows to be re-used in breeding or embryo transfer programs.

Atosiban is useful in improving the pregnancy outcome of in vitro fertilization-embryo transfer (IVF-ET) in patients with repeated implantation failure. The pregnancy rate improved from zero to 43.7%. First- and second-trimester bleeding was more prevalent in ART than in spontaneous pregnancies. From 2004 to 2010, 33 first-trimester pregnancies with vaginal bleeding after ART with evident uterine contractions, when using atosiban and/or ritodrine, no preterm delivery occurred before 30 weeks.

A paternity test is conducted to prove paternity, that is, whether a male is the biological father of another individual. This may be relevant in view of rights and duties of the father. Similarly, a maternity test can be carried out. This is less common, because at least during childbirth and pregnancy, except in the case of a pregnancy involving embryo transfer or egg donation, it is obvious who the mother is.

Adaptaur cattle are early maturing and of a medium size with a short dark red pigmented coat and good resistance to internal parasites. Some Adaptaurs carry a gene that produces extremely high resistance to cattle ticks and the Australian Hereford Society is assisting to increase frequency of the gene by embryo transfer. It is capable of producing substantial hybrid vigor when used for crossbreeding. The F1 progeny grow faster and are more fertile than Brahmans.

Tina goes through with the embryo transfer, despite concerns from Rita and Tommy's opposition. Unable to cope with Tina being pregnant with Izzy and Gary's baby, Tommy ends their relationship. In January 2013, Tina helps Tyrone and Fiz run away with Tyrone's daughter, Ruby, after Kirsty falsely accuses Tyrone of domestically abusing her. Tina feels suffocated by the Windass family as her pregnancy progresses and is shocked when Gary tries to kiss her.

Figure 1: The exchange of chromosomal segments between chromosomes 4 to 20. Since no segments are lost, this is a balanced translocation. The successful implantation of an embryo not only relies on a receptive uterine environment in the mother but also on the quality of the embryo itself. Embryo quality and probability of implantation can be affected by maternal and paternal genetic abnormalities as well as zona pellucida dysfunction and poor embryo transfer technique.

Female infertility may be overcome by assisted reproduction technology, particularly embryo transfer techniques. Male infertility caused by absence of the vas deferens may be overcome with testicular sperm extraction, collecting sperm cells directly from the testicles. If the collected sample contains too few sperm cells to likely have a spontaneous fertilization, intracytoplasmic sperm injection can be performed. Third party reproduction is also a possibility for women with CF. Whether taking antioxidants affects outcomes is unclear.

There is no universally accepted definition of the term. Thus in IVF pregnancy rates may be based on initiated treatment cycles, cycles that underwent oocyte retrieval, or cycles where an embryo transfer was performed. In terms of outcome, "pregnancy" may refer to a positive pregnancy test, evidence of a pregnancy with a "viable" fetus or implantation. Furthermore, pregnancy rates can be influenced in IVF by transferring multiple embryos that may result in multiple births.

It was later combined with an egg from a female, creating embryos in March 2005. Those embryos were frozen for almost six years before being thawed and transferred to a surrogate female in December 2010, which carried the embryos to term, resulting in the birth of the two kittens. The same center reported that on 6 February 2012, a female black-footed cat kitten, Crystal, was born to a domestic cat surrogate after interspecies embryo transfer.

ET also allows the continued use of animals such as competition mares to continue training and showing, while producing foals. The general epidemiological aspects of embryo transfer indicates that the transfer of embryos provides the opportunity to introduce genetic material into populations of livestock while greatly reducing the risk for transmission of infectious diseases. Recent developments in the sexing of embryos before transfer and implanting has great potential in the dairy and other livestock industries.Embryo Sexing Technology .

Haryana, with 660 grams of availability of milk per capita per day, ranks at number two in the country compared to the national average of 232 grams.Haryana 2nd in milk yield There is a vast network of milk societies that support the dairy industry. The National Dairy Research Institute at Karnal, and the Central Institute for Research on Buffaloes at Hisar are instrumental in development of new breeds of cattle and propagation of these breeds through embryo transfer technology.

Embryo transfer is recommended as a method of reproduction to reduce the chances of contracting the disease, as long as the disease status of the donor cow is checked. It is not recommended to rebreed heifers or cows that have this disease. Seropositive animals should be culled. To prevent horizontal transmission it is important to prevent the contamination of feed and water via the shedding of oocysts by dogs and possibly other canids like the fox.

In South Africa a composite of Tuli and Limousin cattle has recently been developed, named Tulim cattle. When Australia decided to import the breed, it used embryo transfer in order to limit the possible transfer of African cattle diseases and parasites. The Tuli breed was founded by the Rhodesian Government at a Government station situated on the Banks of the Tuli River. The purpose was to establish an indigenous breed suited to the prevailing hot dry conditions.

The “École Supérieure du Cheval et de l'Équitation” (“Higher School for Horses and Riding”) is present on the Pin site, having at its disposal high quality training in saddlery, blacksmithing, riding of young horses and combined driving. The broodmare band conducts genetic research on horse breeding. In 2014, four foals, two females and two males, were born from an embryo transfer. This method, the first of its kind in Europe, will enable the maintenance of rare and endangered horse breeds.

The use of fertility medication that stimulates the ovary to release multiple eggs and of IVF with embryo transfer of multiple embryos has been implicated as an important factor in preterm birth. Maternal medical conditions increase the risk of preterm birth. Often labor has to be induced for medical reasons; such conditions include high blood pressure, pre-eclampsia, maternal diabetes, asthma, thyroid disease, and heart disease. In a number of women anatomical issues prevent the baby from being carried to term.
|
|
Embryo transfer and artificial insemination also account for a small number of new infections if common equipment and/or palpation sleeves are used. While transmission has been documented via blood feeding insects, the significance of this risk is unclear. Transmission relies primarily on the transfer of infected lymphocytes from one animal to the next, and BLV positive animals with lymphocytosis are more likely to provide a source for infection. Virus particles are difficult to detect and not used for transmission of infection.

At the time of embryo transfer, it is favorable to have an endometrium of a thickness of between 7 and 14 mm with a triple-line configuration, which means that the endometrium contains a hyperechoic (usually displayed as light) line in the middle surrounded by two more hypoechoic (darker) lines. A triple-line endometrium reflects the separation of the stratum basalis and functionalis layers, and is also observed in the periovulatory period secondary to rising estradiol levels, and disappears after ovulation.

Brahmousin cattle are a hybrid purebred breed of Brahman and Limousin first created in the USA in the late 1970s. The goal was to blend the best of the Limousin and Brahman traits to create a breed that has reproductive efficiency, mothering ability, good muscling and growth traits, and adaptability to varying environmental conditions. Brahmousin are now bred in the USA, Indonesia, El Salvador, and Australia. The first Brahmousin cattle were produced from a multiple embryo transfer from a French-imported Limousin dam.

A few horses live in the Netherlands, Switzerland and Luxembourg, as well as in North America. Since 2006, twenty horses, including two registry-approved breeding stallions, have been exported from France to Denmark to create a stud farm in that country. The French national stud, the Haras Nationaux, allows the registration of horses bred using artificial insemination and embryo transfer, but does not allow the registration of cloned horses. It considers the breed to be endangered, along with several other French draft breeds.

Regarding spontaneous or natural monozygotic twinning, a recent theory proposes that monozygotic twins are probably formed when a blastocyst contains two inner cell masses (ICM), each of which will lead to a separate fetus, rather than by the embryo splitting while hatching from the zona pellucida (the gelatinous protective coating around the blastocyst). Monozygotic twins may also be created artificially by embryo splitting. It can be used as an expansion of in vitro fertilization (IVF) to increase the number of available embryos for embryo transfer.

Two genes have been identified to assist in the development and receptivity of the uterus and endometrium, Hoxa10 and Hoxa11. Hoxa10 has been shown to change the upper uterine segment into oviduct-like structures, creating a smaller uterus that appears normal. Embryo transfer into the lower uterine segment does not allow for implantation, so the Hoxa10 gene has multiple effects throughout the uterus. Hoxa11 mutations alter the endometrial gland development and reduce the secretion of Leukaemia-Inhibitory factor (LIF) which is required for implantation.

In such cases the normally necessary steps of isolation and growth of the organism in culture may be omitted, thus allowing the sequencing of a much greater spectrum of organism genomes. Single cell genome sequencing is being tested as a method of preimplantation genetic diagnosis, wherein a cell from the embryo created by in vitro fertilization is taken and analyzed before embryo transfer into the uterus. After implantation, cell-free fetal DNA can be taken by simple venipuncture from the mother and used for whole genome sequencing of the fetus.
|
|
The embryo transfer procedure starts by placing a speculum in the vagina to visualize the cervix, which is cleansed with saline solution or culture media. A soft transfer catheter is loaded with the embryos and handed to the clinician after confirmation of the patient's identity. The catheter is inserted through the cervical canal and advanced into the uterine cavity. There is good and consistent evidence of benefit in ultrasound guidance, that is, making an abdominal ultrasound to ensure correct placement, which is 1–2 cm from the uterine fundus.
|
|
Fertilization may be performed using the woman's partner's sperm or by using donor sperm. 'Spare' embryos which are created for another couple undergoing IVF treatment but which are then surplus to that couple's needs may also be transferred (called embryo donation). Embryos may be specifically created by using eggs and sperm from donors and these can then be transferred into the uterus of another woman. A surrogate may carry a baby produced by embryo transfer for another couple, even though neither she nor the 'commissioning' couple is biologically related to the child.

Advances in assisted reproductive technology (ART) have revolutionized the ability to help men with even the severest forms of male infertility to become fathers. This field began in earnest in 1978 when the first successful in vitro fertilization (IVF) cycle was performed. This technique involves controlled ovarian stimulation followed by egg retrieval, in vitro fertilization, and embryo transfer to the uterus. In the United States, the number of babies born to infertile couples with IVF has risen logarithmically from 260 babies in 1985 to almost 50,000 in 2003.

The southern calves are typically reared on pasture and sold as weaners, yearlings or as steers at about two years old or older. Artificial insemination and embryo transfer are more commonly used in stud cattle breeding in Australia, but may be used in other herds.Beattie, William A., Beef Cattle Breeding & Management, Popular Books, 1990, In the Top End, sub-tropical areas and in arid inland regions cattle are bred on native pastures on expansive cattle stations. Anna Creek Station in South Australia, Australia is the world's largest working cattle station.

IVF avails for embryo transfer of the appropriate number of embryos to give good chances of pregnancy with minimal risk of multiple birth. A review of randomized studies came to the result that IVF in couples with a high chance of natural conception, as compared to IUI/ICI with or without ovarian stimulation, was more effective in three studies and less effective in two studies. There is no evidence for an increased risk of ovarian hyperstimulation syndrome (OHSS) with IVF when compared with ovarian stimulation combined with IUI.

Horse and Rider. Retrieved April 4, 2014 Due to the cancellation of Badminton in 2012 Badminton have agreed to hold this at the 2013 event instead. Always small compared to the competition, her competitive spirit, manoeuvrability, sheer guts and a Will To Win have propelled her to the top. The plan is to enjoy competing her at a much lower level, breed more foals by Embryo Transfer and eventually hand the reins over to 8 year old Ellie who is champing at the bit to take the ride on.

Among gestational surrogacy arrangements, between 19%-33% of gestational surrogates will successfully become pregnant from an embryo transfer. Of these cases, 30-70% will successfully allow the intended parent(s) to become parent(s) of the resulting child. For surrogate pregnancies where only one child is born, the preterm birth rate in surrogacy is marginally lower than babies born from standard IVF (11.5% vs 14%). Babies born from surrogacy also have similar average gestational age as infants born through in vitro fertilization and oocyte donation; approximately 37 weeks.

Although she appeared tender at the walk, the mare still showed her brilliant trot and lovely canter work and flying changes. The bidding included the likes of German Grand Prix rider Gina Capellmann Lutkemeier, who stopped her bidding at 700,000 euro, but the eight- year-old Brandenburger was finally purchased for 900,000 Euros by Xavier Marie, owner of Haras de Hus, a stud farm in France. Also sold at the auction was A Special Poetin (by Jazz), the first embryo transfer foal of Poetin. The beautiful black filly was bought back by Peter van der Zwan via an agent.

Donor sperm is less commonly used for IVF treatments than for artificial insemination. This is because IVF treatments are usually required only when there is a problem with the female conceiving, or where there is a 'male factor problem' involving the female's partner. Donor sperm is also used for IVF in surrogacy arrangements where an embryo may be created in an IVF procedure using donor sperm and this is then implanted in a surrogate. In a case where IVF treatments are employed using donor sperm, surplus embryos may be donated to other women or couples and used in embryo transfer procedures.

Since the 1970s, Gleicher has published hundreds of scientific articles, abstracts and book chapters on reproductive endocrinology and infertility. He was one of the founders of the American Journal of Reproductive Immunology, where he also served as editor-in-chief. For 30 years, he was editor of the Journal of In Vitro Fertilization and Embryo Transfer, now known as the Journal of Assisted Reproduction and Genetics. Other publications in which he served as editor or member of the editorial board include The Mount Sinai Journal of Medicine, International Journal of Obstetrics and Gynecology, Asian Pacific Journal of Reproduction and PLOS One, among others.

In the human, the uterine lining (endometrium) needs to be appropriately prepared so that the embryo(s) can implant. In a natural cycle the embryo transfer takes place in the luteal phase at a time where the lining is appropriately undeveloped in relation to the status of the present Luteinizing Hormone. In a stimulated or a cycle where a "frozen" embryo is transferred, the recipient woman could be given first estrogen preparations (about 2 weeks), then a combination of estrogen and progesterone so that the lining becomes receptive for the embryo. The time of receptivity is the implantation window.
|
|
It is uncertain whether there is any difference in live birth rate between transfer on day two or day three after fertilization. Monozygotic twinning is not increased after blastocyst transfer compared with cleavage-stage embryo transfer. There is a significantly higher odds of preterm birth (odds ratio 1.3) and congenital anomalies (odds ratio 1.3) among births having reached the blastocyst stage compared with cleavage stage. Because of increased female embryo mortality due to epigenetic modifications induced by extended culture, blastocyst transfer leads to more male births (56.1% male) versus 2 or 3 day transfer (a normal sex ratio of 51.5% male).
|
|
For egg donation, there is evidence of a lower pregnancy rate and a higher cycle cancellation rate when the progesterone supplementation in the recipient is commenced prior to oocyte retrieval from the donor, as compared to commenced day of oocyte retrieval or the day after. Seminal fluid contains several proteins that interact with epithelial cells of the cervix and uterus, inducing active gestational immune tolerance. There are significantly improved outcomes when women are exposed to seminal plasma around the time of embryo transfer, with statistical significance for clinical pregnancy, but not for ongoing pregnancy or live birth rates with the limited data available.

|
The traditional method for selection of embryos to be used for embryo transfer in fertility treatments such as IVF, involves assessing the morphology of a fertilized egg at crucial time points under a microscope. The incorporation of time lapse imaging tools in an incubator is a novel technology that allows images of embryo development to be captured frequently. This together with softwares allows embryologists and clinicans to interpret the embryo development information captured and select embryos for transfer in IVF treatment. Research for an algorithm to select a single embryo that would lead to the best clinical pregnancy outcome is underway.

Sperm, eggs, and embryos can now be frozen and kept in banks, which are sometimes called "Modern Noah's Arks" or "Frozen Zoos". Cryopreservation techniques are used to freeze these living materials and keep them alive in perpetuity by storing them submerged in liquid nitrogen tanks at very low temperatures. Thus, preserved materials can then be used for artificial insemination, in vitro fertilization, embryo transfer, and cloning methodologies to protect diversity in the gene pool of critically endangered species. It can be possible to save an endangered species from extinction by preserving only parts of specimens, such as tissues, sperm, eggs, etc.

They included a denizen of hell, a lion, and a god (deva) in a heavenly realm just before his last birth as the 24th tirthankara. Svetambara texts state that his embryo first formed in a Brahman woman before it was transferred by Hari-Naigamesin (the divine commander of Indra's army) to the womb of Trishala, Siddhartha's wife. The embryo-transfer legend is not believed by adherents of the Digambara tradition. Jain texts state that after Mahavira was born, the god Indra came from the heavens along with 56 dipkumaries, anointed him, and performed his abhisheka (consecration) on Mount Meru.

A depiction of the procedure of in-vitro fertilisation. Theoretically, IVF could be performed by collecting the contents from a woman's fallopian tubes or uterus after natural ovulation, mixing it with sperm, and reinserting the fertilised ova into the uterus. However, without additional techniques, the chances of pregnancy would be extremely small. The additional techniques that are routinely used in IVF include ovarian hyperstimulation to generate multiple eggs, ultrasound-guided transvaginal oocyte retrieval directly from the ovaries, co-incubation of eggs and sperm, as well as culture and selection of resultant embryos before embryo transfer into a uterus.

A stallion being driven at the Cluny Stud As it has been since the creation of the Auxois stud book, only purebred horses and Ardennes and Trait du Nord crosses are allowed to be registered. This is to ensure selection for the desired breed characteristics, which are now a lighter and more active horse than was seen during the time of breeding for horse meat. Horses bred through artificial insemination and embryo transfer are allowed to be registered; those potentially bred through cloning are not. The Syndicat du Cheval de Trait Auxois (Auxois Draft Horse Association) is the national registry, managing the stud book, breed standard and promotion of the breed.

In 1997, after Stoddart heard a radio show talking about British frozen embryos being destroyed, Nightlight established an embryo "adoption" program to enable infertile couples to gain access to frozen embryos.Beauchaine. Nightlight describes the process as an "adoption" because they match embryo donors with recipients using practices commonly used in traditional adoptions. The U.S. Health and Human Services agency has given grants to Nightlights's Snowflakes program and others to promote "embryo adoption." Until Stoddart conceived of his program, embryo transfer was typically arranged by medical doctors, but Stoddart hoped positioning the transfer as an adoption would increase the number of embryos implanted in women and brought to term.

Additionally, the mitochondria in the cytoplasm also contains DNA and during SCNT this mitochondrial DNA is wholly from the cytoplasmic donor's egg, thus the mitochondrial genome is not the same as that of the nucleus donor cell from which it was produced. This may have important implications for cross-species nuclear transfer in which nuclear-mitochondrial incompatibilities may lead to death. Artificial embryo splitting or embryo twinning, a technique that creates monozygotic twins from a single embryo, is not considered in the same fashion as other methods of cloning. During that procedure, a donor embryo is split in two distinct embryos, that can then be transferred via embryo transfer.

Oleg Deripaska established Kuban Agroholding, a massive agribusiness in southern Russia. The company integrates two dairy farms, а 16,000 pig capacity breeding complex, three elevators with non-recurrent grain storage capacity of more than 270,000 tonnes, three-seed plants, a sugar factory and the Sunrise horse breeding farm, specializing in the breeding of English thoroughbred horses. It is one of the top-20 largest agribusinesses and top-5 most efficient land users in Russia. Kuban Agroholding is one of the few agrocompanies in Russia involved in embryo transfer technology that allows for the reproduction of high- yielding milk cows out of less productive recipients.

Egg donors are first recruited, screened, and give consent before participating in the IVF process. Once the egg donor is recruited, she undergoes IVF stimulation therapy, followed by the egg retrieval procedure. After retrieval, the ova are fertilized by the sperm of the male partner (or sperm donor) in the laboratory, and, after several days, the best resulting embryo(s) is/are placed in the uterus of the recipient, whose uterine lining has been appropriately prepared for embryo transfer beforehand. The recipient is usually, but not always, the person who requested the service and then will carry and deliver the pregnancy and keep the baby.

The embryo implanted in the surrogate may be fertilised using sperm from the male partner of the 'commissioning couple', or by using sperm provided by a sperm donor. Embryo donation is where extra embryos from a successful IVF of a couple are given to other couples or women for transfer with the goal of producing a successful pregnancy. Embryos for embryo donation may also be created specifically for embryo transfer using donor eggs and sperm, or in some cases donor eggs and donor sperm. It may thus be seen as a combination of sperm donation and egg donation, since what is donated is a combination of these.

Women with Mullerian anomalies often utilise assisted reproductive technologies such as in vitro fertilisation (IVF), intracytoplasmic sperm injection (ICSI) and embryo transfer (ET), and/or a gestational carrier. Compared to individuals with no uterine anomalies, women with Mullerian anomalies exhibit no differences in number of follicles produced, number of oocytes retrieved, or levels of estrogen produced. The normal follicular function, oocyte population and estrogen levels in women with Mullerian anomalies occurs as normal ovarian function is not compromised in the disease. In patients with uterine anomalies, there may be a chance that the endometrial cavity can be compromised, such that implantation following IVF does not always lead to a successful pregnancy.

|
Embryo cryopreservation is generally performed as a component of in vitro fertilization (which generally also includes ovarian hyperstimulation, egg retrieval and embryo transfer). The ovarian hyperstimulation is preferably done by using a GnRH agonist rather than human chorionic gonadotrophin (hCG) for final oocyte maturation, since it decreases the risk of ovarian hyperstimulation syndrome with no evidence of a difference in live birth rate (in contrast to fresh cycles where usage of GnRH agonist has a lower live birth rate). The main techniques used for embryo cryopreservation are vitrification versus slow programmable freezing (SPF). Studies indicate that vitrification is superior or equal to SPF in terms of survival and implantation rates.

Production of AMH regulates folliculogenesis by inhibiting recruitment of follicles from the resting pool in order to select for the dominant follicle, after which the production of AMH diminishes. As a product of the granulosa cells, which envelop each egg and provide them energy, AMH can also serve as a molecular biomarker for relative size of the ovarian reserve. In humans, this is helpful because the number of cells in the follicular reserve can be used to predict timing of menopause. In bovine, AMH can be used for selection of females in multi- ovulatory embryo transfer programs by predicting the number of antral follicles developed to ovulation.

During this time, he worked on problems in embryo culture, embryo transfer, cryobiology, sperm preservation, and the statistics of experimental design. Biggers was a founding member and president of the Society for the Study of Reproduction, won several awards for his research from organizations like the Bedford Stem Cell Research Foundation, and authored more than 250 scientific papers. In addition to experimentation and mentoring, Biggers engaged publicly in ethical and policy advocacy regarding IVF technology. Howard W. Jones credited Biggers with providing critical support for the initiation of clinical IVF in the United States, which led to the first American baby being born by means of IVF.

Suleman's octuplets were conceived by in vitro fertilization (IVF) conducted by Dr. Michael Kamrava. Suleman claimed to have requested implantation of six embryos that she had accumulated from previous IVF treatments, despite being informed that the recommended guideline limit for a woman her age was three. She stated she wanted all six transferred, as they were all that remained from previous harvest cycles, and she neither wanted to destroy them nor to continue paying for their frozen storage. A subsequent Medical Board of California investigation revealed that 29 embryos remained in frozen storage; nevertheless, Suleman underwent a fresh embryo transfer cycle, and Dr. Kamrava transferred twelve fresh blastocysts into Suleman at her request.

The operation takes about 45 minutes. The traction device is then tightened daily so the olive is pulled inwards and stretches the vagina by approximately 1 cm per day, creating a vagina approximately 7 cm deep in 7 days, although it can be more than this.. Another approach is the use of an autotransplant of a resected sigmoid colon using laparoscopic surgery; results are reported to be very good with the transplant becoming a functional vagina. Uterine transplantation has been performed in a number of people with MRKH, but the surgery is still in the experimental stage. Since ovaries are present, people with this condition can have genetic children through IVF with embryo transfer to a gestational carrier.

Increasing the productivity of embryo transfer and artificial insemination is economically profitable as the costs associated with veterinarian and semen services are reduced. The reduction of costs occur because vets are required for less time to do the inseminating because the period of ovulation of the herd is decreased to 2-5 days. There are many different injection methods that have been put into practise in order to manipulate the estrous cycle. These involve injections into each cow with a measured amount of progesterone or progestin and waiting 5-7 days, or until heat signals occur, before moving onto different impregnating methods such as joining the cows or heifers with a bull.

The main durations of embryo culture are until cleavage stage (day two to four after co-incubation) or the blastocyst stage (day five or six after co-incubation). Embryo culture until the blastocyst stage confers a significant increase in live birth rate per embryo transfer, but also confers a decreased number of embryos available for transfer and embryo cryopreservation, so the cumulative clinical pregnancy rates are increased with cleavage stage transfer. Transfer day two instead of day three after fertilisation has no differences in live birth rate. There are significantly higher odds of preterm birth (odds ratio 1.3) and congenital anomalies (odds ratio 1.3) among births having from embryos cultured until the blastocyst stage compared with cleavage stage.

A number of other studies have also investigated the use of progesterone by sublingual administration. Older studies have also explored sublingual progesterone. A study of sublingual progesterone for luteal support in patients undergoing embryo transfer found that after sublingual administration of 50 or 100 mg progesterone dissolved in a 1 mL suspension, peak levels of progesterone were reached in 30 to 60 minutes and were on average 17.61 ± 3.78 ng/mL with the 100-mg dose. However, the duration was short, with levels of less than 5 ng/mL at 6 hours, and re- administration had to be done two or three times per day for adequate circulating levels of progesterone to be maintained throughout the day.

Pregnant livestock usually receive special care in late pregnancy and stockmen may have to deal with dystocia (abnormal or difficult birth or labour). A good stockman is aware of livestock behavioural characteristics, and has an awareness of flight zone distances of the livestock being handled. Apart from livestock duties a stock person will inspect, maintain and repair fences, gates and yards that have been broken by storms, fallen trees, livestock and wildlife. A head stockman is responsible for a number of workers and a range of livestock and property operations including the supervision of operations that includes feeding, mating, managing artificial breeding and embryo transfer programs; managing vehicle and equipment maintenance; repair and maintenance of property structures; supervising and training of staff.

Adjunctive antibiotics in the form of amoxicillin plus clavulanic acid probably does not increase the clinical pregnancy rate compared with no antibiotics. For frozen-thawed embryo transfer or transfer of embryo from egg donation, no previous ovarian hyperstimulation is required for the recipient before transfer, which can be performed in spontaneous ovulatory cycles. Still, various protocols exist for frozen-thawed embryo transfers as well, such as protocols with ovarian hyperstimulation, protocols in which the endometrium is artificially prepared by estrogen and/or progesterone. There is some evidence that in cycles where the endometrium is artificially prepared by estrogen or progesterone, it may be beneficial to administer an additional drug that suppresses hormone production by the ovaries such as continuous administration of a gonadotropin releasing hormone agonist (GnRHa).

An Appendix Quarter Horse is a horse that has either one Quarter Horse parent and one parent of any other eligible breed (such as Thoroughbred, the most common Appendix cross), two parents that are registered Appendix Quarter Horses, or one parent that is a Quarter Horse and one parent that is an Appendix Quarter Horse. AQHA also issues a "Racing Register of Merit", which allows a horse to race on Quarter Horse tracks, but not be considered a Quarter Horse for breeding purposes (unless other requirements are met).AQHA.com A stallion who has won many races may be put up to stud when he is retired. Artificial insemination and embryo transfer technology (allowed only in some breeds) has brought changes to the traditions and ease of breeding.

Dr. John E. Buster John Edmond Buster (born July 18, 1941) is an American physician who, while working at the University of California at Los Angeles School of Medicine, directed the research team that performed the first embryo transfer from one woman to another resulting in a live birth. It was performed at the Harbor-UCLA Medical Center, reported in July 1983, and culminated in the announcement of the birth on February 3, 1984. In the procedure, an embryo that was just beginning to develop was transferred from the woman in whom it had been conceived by artificial insemination to another woman who gave birth to the infant 38 weeks later. The sperm used in the artificial insemination came from the husband of the woman who bore the baby.

For example, the placental glycosylation pattern at the fetomaternal interface should optimally be similar to that of the host species. Yet, for some species, such as a Bactrian camel embryo inside a Dromedary, pregnancy can be carried to term with no other intervention than the embryo transfer. This is possible for gaur embryos inside cattle as well, but with severe intrauterine growth restriction, with uncertainty of how much is caused by the IVF procedure itself, and how much is caused by interspecies incompatibility. The ability of one species to survive inside the uterus of another species is in many cases unidirectional; that is, pregnancy would not necessarily be successful in the inverse situation where a fetus of the other species would be transferred into the uterus of the first one.

Dignitas Personae is the title of a 2008 instruction by the Congregation for the Doctrine of the Faith giving doctrinal directives on certain embryonic ethical controversies that had emerged since 1987, after Donum Vitae was released. The document takes a critical stance against selective reduction, prenatal diagnosis, preimplantation diagnosis, in vitro fertilization, cryopreservation, embryo transfer, some forms of genetic engineering, embryo donation, which have been criticized as unethical by pro-life ethicists because they provoke the termination of embryonic cell reproduction. The doctrinal material is not only addressed to Catholic couples, but also to pharmacists, doctors, ethicists, theologians, politicians and industrialists so that they may try to tackle these issues together. Other related documents, such as Humanae Vitae, were also written for a wide variety of individuals and specialists on the matter.

The transcriptomes of stem cells and cancer cells are of particular interest to researchers who seek to understand the processes of cellular differentiation and carcinogenesis. A pipeline using RNA-seq or gene array data can be used to track genetic changes occurring in stem and precursor cells and requires at least three independent gene expression data from the former cell type and mature cells. Analysis of the transcriptomes of human oocytes and embryos is used to understand the molecular mechanisms and signaling pathways controlling early embryonic development, and could theoretically be a powerful tool in making proper embryo selection in in vitro fertilisation. Analyses of the transcriptome content of the placenta in the first-trimester of pregnancy in in vitro fertilization and embryo transfer (IVT-ET) revealed differences in genetic expression which are associated with higher frequency of adverse perinatal outcomes.

The Australian White (AW) was developed on the Tattykeel properties in Black Springs, NSW, Australia by two brothers, Graham and Martin Gilmore, over several years and was launched in 2011. Utilizing embryo transfer, artificial insemination, and selective line breeding, the “best” characteristics of the four source breeds were used to develop the AW. The original design was to be a self-replacing meat sheep that sheds its own hair, can survive in extreme weather conditions (from cold and wet to hot and arid environments), early maturing, and breed year-round. During the development of the breed its unique eating qualities were evident; however, it was not until later (November 2016) that the scientific reasons for its excellent eating qualities were discovered by Associate Professor Aduli E.O. Malau-Aduli, PhD. The AW breed can now be found all over the world in countries such as New Zealand, China, Inner Mongolia, and the United States.

In cases where the recipient's womb is absent or unable to carry a pregnancy, or in cases involving gay male couples, a gestational surrogate is used and the embryos are implanted into her per an agreement with the recipients. The combination of egg donation and surrogacy has enabled gay men, including singer Elton John and his partner, to have biological children. Oocyte and embryo donation now account for approximately 18% of in vitro fertilization recorded births in the US. This work established the technical foundation and legal-ethical framework surrounding the clinical use of human oocyte and embryo donation, a mainstream clinical practice, which has evolved over the past 25 years. Building upon this groundbreaking research and since the initial birth announcement in 1984, well over 47,000 live births resulting from donor oocyte embryo transfer have been and continue to be recorded by the Centers for Disease Control (CDC) in the United States to infertile women, who otherwise would not have had children by any other existing method.
