Surrogacy is an agreement under which a woman carries and gives birth to a child for another person or couple. Women usually consider surrogacy if they have problems with their uterus, after a hysterectomy, with medical conditions that make pregnancy impossible or risky, and if they have tried but failed to conceive using various assisted reproduction methods, such as IVF. Surrogate motherhood is also chosen by people who cannot adopt a child due to their age or marital status, same-sex couples and single people. There are two types of surrogacy, traditional and gestational. With the traditional type, the egg of the surrogate mother is used, and therefore she has a genetic connection with the child. This method is prohibited in some countries. The most common method is gestational surrogacy. With the help of in vitro fertilization (IVF), the ovum of the intended mother is fertilized with the sperm of the intended father, the resulting embryo is transferred to the uterus of the surrogate mother. With this method, the surrogate mother has no genetic connection with the child.
