IVF / Gestational surrogacy - This is a more common form of surrogacy. In this procedure, a woman carries a pregnancy created by the egg and sperm of the genetic couple. The egg of the wife is fertilized in vitro by the husband's sperms by IVF/ICSI procedure, and the embryo is transferred into the surrogate's uterus, and the surrogate carries the pregnancy for nine months. The child is not genetically linked to the surrogate.
Traditional / Natural surrogacy - This is where the surrogate is inseminated or IVF/ICSI procedure is performed with sperms from the male partner of an infertile couple. The child that results is genetically related to the surrogate and to the male partner but not to the female partner.
