IVF protocols

The IVF protocol is a scheme for preparing a woman for the in vitro fertilization procedure. It is necessary to increase the chances of the patient achieving pregnancy. The IVF protocol is selected by the reproductologist individually for each woman. At the same time, many factors are taken into account (age, state of reproductive function, ovarian ovarian reserve, individual sensitivity to medications). Standard protocols include ovulation stimulation, follicle puncture, embryo transfer, and support for possible pregnancy with progesterone drugs. They are divided into long and short.With undisturbed ovarian function, IVF can be carried out in a natural cycle, that is, without ovulation stimulation. Cryoprotocol and the Japanese protocol are also distinguished. Natural, ultrashort and Japanese protocols are less financially costly for the patient.IVF in the natural cycle EKO in the natural menstrual cycle is carried out for women who do not have a normal hormonal status and ovulation occurs regularly. The advantage of such a protocol is to obtain a high-quality egg, the maturation process of which is not disrupted by the introduction of artificial hormonal drugs. The disadvantage of the method is the insufficiently high chances of pregnancy in comparison with stimulated protocols, since during its implementation, only one embryo is most often transplanted. The exception is when a woman in a natural cycle matures several eggs at once, but this happens extremely rarely. In addition, when performing IVF in a natural cycle, it is difficult for a doctor to calculate the time at which a follicle puncture should be performed. Ovulation often occurs before the scheduled date of puncture. In this case, the process of in vitro fertilization has to be postponed to the next menstrual cycle.Long protocol The eco-long protocol lasts about 40-50 days. It is distinguished by full control over the hormonal background of a woman and obtaining the maximum possible number of eggs. A long protocol is indicated for patients suffering from hormone-dependent diseases: endometriosis, hyperandogeny, uterine fibroids. It is divided into regulatory and stimulating phases.About a week before the expected menstruation, a woman is injected with special pharmaceuticals that "turn off" her own hormonal regulation (diferelin, buserelin, etc.). Their administration lasts for 12-22 days.Then, on the 3-5 day of the next menstrual cycle, drugs that stimulate ovarian function (pregnil, puregol, etc.) are prescribed for 10-17 days. They cause the maturation of many eggs. The growth of follicles is monitored by ultrasound and, when they reach pre-ovulatory sizes, the reproductologist prescribes a drug that stimulates the onset of ovulation, for example, chorionic gonadotropin. Then, after about 36 hours, the follicles are punctured and the eggs are extracted. After the embryo is transplanted into the uterus, progesterone drugs are prescribed to a woman, which are canceled if the onset of pregnancy is not confirmed by a laboratory blood test for the concentration of b-hCG.The advantage of this protocol is that even despite the possible hormonal imbalance in a woman, it is possible to achieve the maturation of a large number of eggs and the endometrial growth necessary for embryo implantation. However, the implementation of this technique may be complicated by the development of hyperstimulation, which in turn often disrupts the natural menstrual cycle for a long time.Short protocol Ecoprime during a short protocol, drugs that temporarily "turn off" the function of the pituitary gland are administered only from 3-5 days of the menstrual cycle and in a small dosage. That is, the regulatory phase, unlike the long protocol, is practically absent during this technique. Simultaneously with the introduction of small doses of drugs that block the function of the pituitary gland, gonadotropins are introduced that stimulate the growth of follicles and the maturation of eggs. Then, as with a long protocol, HCG injection, follicle puncture and prescribing progesterone preparations follow.This protocol is most often prescribed to women who have healthy ovaries and are over 35 years old. Its advantage is a shorter duration compared to a long protocol and a reduced likelihood of developing the effect of hyperstimulation. The disadvantages of the short protocol are unevenly maturing eggs and the likelihood of premature (occurred before the appointed time of puncture) ovulation.One of the varieties of this technique is the ultrashort protocol. Antagonists (special pharmaceuticals) are used as "blockers" of the pituitary gland during its implementation, which significantly reduce the likelihood of premature ovulation.Japanese Protocol An eco-characteristic feature of the Japanese protocol protocol is the stimulation of the ovaries with low doses of drugs. The resulting embryos are then usually cryopreserved and transferred to the uterine cavity already in the next menstrual cycle of a woman after defrosting. As a result of the Japanese protocol, it is possible to obtain high-quality eggs and avoid many complications.Women who have failed to achieve pregnancy during one or another type of protocol are recommended to try again using a different stimulation scheme or try IVF in a natural cycle.
