A surrogate is a woman who agrees to carry a pregnancy for another person or couple, called the intended parent(s). The current and more accurate term for surrogate is carrier.

NAFG conducts gestational surrogacies, in which an embryo or embryos created from either sperm and/or egg from the intended couple or donor(s) is transferred to the carrier’s uterus. The baby has no genetic relationship to the carrier, who is only responsible for gestating the baby until birth.

Unlike adoption, surrogacy allows the intended parents to have some or even total genetic relationship to their child, to be fully informed of the child's entire prenatal care and health, and to take their newborn home from the hospital without any anxious waiting or conditions.

Certain states have a legal structure for obtaining a pre-birth order in surrogacy arrangements, which allows the names of the intended parents to appear on the baby's original birth certificate. In other cases, a step-parent adoption takes place. Either way, the intended parents take the baby home from the hospital.
