Surrogacy is the carrying of a pregnancy for people who are unable to do so themselves. There are two types of surrogacy – traditional surrogacy and gestational surrogacy. With traditional surrogacy, the surrogate uses her own eggs, along with the intended father’s or donated sperm. This may be through IUI, IVF, or home insemination. In gestational surrogacy, the baby carried by the surrogate does not contain any of her genetic material. IVF is necessary in this case, where either the intended mother’s egg, or a donor’s egg is combined with the intended father’s or donated sperm to create embryos and replaced into the surrogate’s uterus.
