Gestational Surrogacy is the process whereby an embryo is fertilized via invitro fertilization (IVF), using the egg of the intended mother or an egg donor, and the sperm of the intended father (or fathers – in the case of LGBTQ+ parents). The fertilized embryo is then implanted into a surrogate (often referred to as a gestational carrier, who will then carry the pregnancy full term until birth, when the child/ children is handed to the intended parents. There is no genetic relationship between the child / children and the gestational surrogate.
Traditional surrogates are not only gestational mothers, but most importantly, genetic mothers as well. They undergo artificial insemination, which results in pregnancy.
