Generally, and this is what is recommended, surrogacy is performed through in vitro fertilization (IVF), as this reduces the genetic link between the pregnant woman and the baby who is pregnant. In addition, in this way, the future mother can provide the eggs for the creation of the embryo that will give rise to the birth of her child, in other words, mother and child will be able to share the genetic load.
Surrogacy through artificial insemination is known as traditional surrogacy.
