Embryo donor program is available to any patients that have failed to conceive naturally and cannot be treated by other procedures. Embryo donor program treatment is recommended for women who cannot produce viable eggs and in instances where the fertilized egg fails to develop into an embryo or the embryos obtained from the patients do not survive after transplant. The gynecologist usually suggest embryo donation program to a couple detected with infertility.
For obtaining a viable embryo, the females must be under the age of 35 at the time of egg retrieval and males under the age of 49, for sperm donation. Donors are screened for genetic diseases or illness that can be passed on to the child. In case, the donor knows the recipient or they are related, it is referred to as a known donation. A clinic-recruited donation is also available. Oral contraceptives are prescribed before the process of transfer to suppress the menstrual cycle. Estrogen and progesterone are prescribed to prepare the uterus for receiving the embryo. Frozen embryos are transferred between the 17th to the 19th day of the cycle. A small catheter passed through the vagina to deposit the embryos to the uterus. More than one embryo is usually transferred to enhance the probability of a conception, however, it increases the risks of multiple pregnancies.
Embryo transfer process has rare complications and the risks of infection are very small. Freezing and thawing of embryos has no impact on the health of the newborn baby.
