Gestational carrier IVF utilizes a third party to carry a pregnancy. In this case there is an agreement between the intended parent(s) and a third-party woman, who will carry the baby to term. In these cases, the egg used in the pregnancy is either from the intended mother or from a donor. Similarly, the sperm used is from the intended father or a donor.
Gestational carrier IVF is a treatment option for women with infertility secondary to a uterine cause, some uterine abnormalities, gay men, single men, and women who are unable to safely carry a pregnancy.
