Embryo adoption is also known as embryo donation
It is a procedure that enables embryos created from donor sperm and donor eggs specifically for the purpose of donation to be transferred to infertile patients.

You as a couple may require donor gametes if both partners have an untreatable infertility, recurrent pregnancy loss thought to be related to the embryo and genetic disorders affecting one or both partners.

Eg If your ovarian reserve is extremely poor due to advanced age, AMH levels are bare minimum, if your ovaries has stopped producing eggs, if you have stopped your menstruation, and your partner has a zero sperm count with blood tests suggesting a testis which has gone into failure, in those cases, using your own gametes may not be a feasible option.

Yes, the built of the donor, the personal hygiene, no history of donation in the last 3 months are all taken into account. The donor is tested for communicable diseases including HIV, hepatitis, syphilis. A complete blood count, and hormonal parameters like thyroid, prolactin are also tested.

At the time of sperm collection and also after a quarantine period of 6 months, the frozen sperm sample is checked for communicable disease before it is transferred from the sperm bank to the concerned IVF center for insemination process.

Evaluation includes a comprehensive medical history from both partners, including blood type and Rh factor, and testing for sexually transmitted diseases including HIV, hepatitis and syphilis. Couple is also counseled about the pros and cons of the decision to use donor embryos. A pelvic exam and an assessment of her uterus (womb) is done. If she is in the older age group, a more thorough evaluation should be done, including an assessment of heart function and risk of pregnancy-related diseases. She may also be advised to see a doctor who specializes in high-risk pregnancy.

The success rate of the procedure is almost 50-60% per cycle, provided your endometrial evaluation is normal and there are no other pre-existing morbidities involved.
