An embryo donor is an individual or couple who donates their embryo to another couple in which both the male and female candidates are infertile. This is done to make the interested couple achieve pregnancy. Embryo donation is a form of third-party reproduction, and it can be done anonymously or through a known donor arrangement. The reasons for pursuing embryo donation are because of some individuals who are unable to produce viable embryos themselves. Receipts with some serious medical conditions can become parents with egg donation.
