In vitro fertilization today is the main opportunity to become pregnant with infertility. Its effectiveness has been proven in all forms of infertility, in addition, IVF is often the only way out for couples in which a man is infertile. With a successful conception using this method, women are prescribed certain hormonal drugs to help carry the baby before childbirth.
In vitro fertilization is the combination of an egg and sperm in a test tube, after which they are placed in the uterus of a patient with infertility or a surrogate mother. When pregnancy occurs after this procedure, multiple pregnancies are often encountered, since all fertilized and implanted eggs survive and attach to the uterine walls. If the patient wishes, doctors remove unplanned embryos, but this is very dangerous for pregnancy and can lead to the death of the remaining fetal eggs.
IVF is used if specialists cannot eliminate or cure a factor that prevents successful conception - for example, when pregnancy makes it impossible to remove fallopian tubes or irreversible impairment of their patency. If there is not enough donor sperm, sperm for IVF are removed through puncture or light surgery. In case of male infertility, sperm does not need to be combined with eggs in a test tube - it is simply injected into the uterine cavity, where the sperm independently fulfill their purpose.
After placing a fertilized egg in the uterus, the woman is prescribed hormonal drugs that maintain the tone of the uterine mucosa and significantly increase the likelihood of a successful child bearing. So, for the preparation of the ovaries, subcutaneous injections of "Decapeptyl" and "Dipherelin" are usually used, and premature ovulation at the final stage of stimulation is prevented with the help of intramuscular injections of "Tsetrotida" and "Ogralutran".
To regulate the process of follicle maturation, "Puregon" and "Menopur" are used subcutaneously or intramuscularly, and "Profazi" and "Pregnil" are prescribed to complete the maturation of the oocytes. The drugs "Duphaston" and "Utrozhestan" are used to prepare the uterine mucosa for embryo transfer and are used after fertilization up to twelve to fourteen weeks of pregnancy, when the formation of the placenta ends, which begins to release its own necessary hormones (progesterone).
