IVF with surrogate mother and donor ovocytes
The surrogate mother is necessary when woman is not able to get pregnant and bear the child. The method involves the selection of germ cells (sperm cells in male and ovocytes in female), fertilization, embryo culture, followed by embryo transfer to a surrogate mother uterus. If it is impossible to get ovocytes, the donor material is used.
Indications for the procedure
Surrogate maternity is strictly regulated by law and applies only if there are clear indications, among them are the following:
- Several unsuccessful IVF attempts for unexplained reasons.
- The absence of the uterus due to congenital and acquired causes.
- Internal diseases when pregnancy is contraindicated.
- The presence of adhesions, deformities and congenital malformations of the uterus that cannot be eliminated.
Indications for the use of donor ovocytes are the following conditions:
- Early onset of menopause.
- Insufficient ovarian supply of ovocytes.
- Congenital ovarian hypoplasia.
- The presence of genetic diseases that are likely to be transferred to the future child, etc.
In order to identify indications, contraindications and to determine the state of health of the couple, a comprehensive medical examination is administered, with both laboratory and instrumental methods. The both surrogate mother and the ovocyte donor undergo testing.
Ovocytes obtained from a donor can be either “fresh” or frozen (cryopreserved). There is no difference in the quality of the biomaterial. Frozen ovocytes are most commonly used. They are prepared in advance and stored in special biomaterial banks. This method is convenient because the couple can choose the desired color of the eyes and hair, as well as other parameters that are incorporated at the genetic level. “Fresh” ovocytes are obtained immediately before IVF. Usually in this case, the donor is a close person. Both methods are considered safe and effective.
The participation of a surrogate mother implies only fertilization according to the IVF protocol. The ovocytes obtained from the donor are fertilized with the husband’s sperm and the embryos are cultivated under special conditions. After 3-5 days, the doctor selects one or more embryos and transfers them to the uterus of the surrogate mother. After confirming the fact of pregnancy, the woman undergoes regular specialist check-ups. All legal features of the procedure are prescribed in the contract that is signed by both parties.
