Gestational surrogacy uses an embryo created outside of the surrogate mother’s body, and the embryo is then implanted into the surrogate’s uterus. Using IVF, intended parents can establish a biological relationship to the child by using their own sperm and/or eggs. The eggs are fertilized in an IVF facility outside of the woman’s body, and the embryo is transferred to the gestational carrier’s uterus. Intended parents may also use donor eggs and/or donor sperm to make their embryos.
