Through our donated embryo program we offer patients an excellent opportunity to become pregnant using donated embryos with minimal waiting time. Embryos are created through in vitro fertilization (IVF) with the gametes (egg and sperm) of a couple that underwent IVF because they had difficulty conceiving on their own. Surplus embryos are cryopreserved in liquid nitrogen for future use. Once a couple has completed their family, they may opt to donate their surplus embryos to our practice so another couple may use them, rather than donate them to science or destroy them. These donating parents believe the cryopreserved embryos deserve a chance at life. Their donation is a wonderful and altruistic gift.
