A surrogacy arrangement or surrogacy agreement is the carrying of a pregnancy for intended parents. There are two main types of surrogacy - Gestational and Traditional.
Intended parents may seek a surrogacy arrangement when either pregnancy is medically impossible, pregnancy risks present an unacceptable danger to the mother’s health or is a same sex couple’s preferred method of procreation. If the surrogate receives money for the surrogacy the arrangement is considered commercial surrogacy, if she receives no compensation beyond reimbursement of medical and other reasonable expenses, it is referred to as altruistic.
Gestational surrogacy is also known as host or full surrogacy.
In gestational surrogacy, the pregnancy results from the transfer of an embryo created by in vitro fertilization (IVF), in a manner so that the resulting child is genetically unrelated to the surrogate. Gestational surrogates are also referred to as gestational carriers.
Traditional surrogacy is also known as partial, genetic, or straight surrogacy. In traditional surrogacy, the surrogate is impregnated naturally or artificially, and the resulting child is genetically related to the surrogate.
