surrogate pregnancy
(SER-uh-gut PREG-nun-see)
A type of pregnancy in which a woman carries and gives birth to a baby for a person who is not able to have children. In a surrogate pregnancy, eggs from the woman who will carry the baby or from an egg donor are fertilized with sperm from a sperm donor to make an embryo. The embryo is implanted in the uterus of the surrogate mother, who carries the baby until birth. Surrogate pregnancy may be an option for men or women who want to have children and have had certain anticancer treatments, such as chemotherapy or radiation therapy, that can cause infertility.
