Traditional surrogacy: in which the surrogate either undergoes artificial insemination or IVF with sperm from the male or from a sperm donor. The surrogate herself provides the eggs and is therefore genetically related to the child. This form of surrogacy is the older method and because of the genetic link between the surrogate and the baby there is some downside risk to this form of surrogacy.
Gestational surrogacy: in which the surrogate carries a pregnancy and delivers a child that is created from the egg and the sperm of the intended parents and /or donor egg and /or donor sperm and/or donated embryos in any combination. The key to this type of surrogacy is that the gestational surrogate is not genetically related to the child and acts only as a gestational carrier for the pregnancy.
