Embryo donation is a procedure that enables embryos that were created by couples undergoing fertility treatment to be transferred to infertile patient in order to achieve a pregnancy. Indications for embryo donation include untreatable infertility that involves both partners, untreatable infertility in a single woman, recurrent pregnancy loss thought to be related to embryonic factors, and genetic disorders affecting one or both partners.
The process of embryo donation requires that the recipient undergo the appropriate medical and psychological screening recommended for all gamete donor cycles. In addition, the female partners undergo an evaluation of her uterine cavity and then her endometrium is prepared with estrogen and progesterone in anticipation of an embryo transfer.
Pregnancy following embryo donation depends on the quality of the embryos that were frozen, the age of the women who provided the eggs, and the number of embryos transferred.
