Artificial insemination first made surrogacy possible. A traditional surrogate is a third-party woman who is artificially inseminated with the man’s sperm or receives the fertilized embryo from the couple. She then carries the baby and delivers it for the parents to raise.

Many couples are not able to have their own children, regardless of having a normal sperm or ovarian function due to congenital absence of the uterus or malformations of the reproductive tract.

In some instances, a pregnancy may be contraindicated due to other health issues that jeopardize the life of the mother, or because the medical treatment will expose the fetus to the teratogenic effect of medicines taken during pregnancy.

Therefore, it is feasible to transfer the embryo into another woman who will carry the baby to term. The uterus of the gestational carrier will be synchronized with the ovulation induction of the biological mother in order to create the best possible environment for the embryo.
A complete psychological evaluation and numerous blood screening tests are required, as well as a signed legal agreement among all involved parties.
