hoje a ciência possibilita escolhas para termos filhos: podemos escolher o sexo, o melhor óvulo feminino, o melhor esperma, tudo segundo critérios genéticos. Em Portugal o caso conhecido e mais mediático é o do futebolista Cristiano Ronaldo que têm 3 filhos biológicos duma mulher (s) "emprestada" embora nada se saiba pode, pode bem ser o caso de óvulos biológicos diferentes com um útero diferente.

Traditional surrogacy, in which the surrogate mother is also the
biological mother, may be the oldest form of assisted reproduction.
Genesis tells of Abraham’s servant Haga bearing a child to be raised by
his genetic father, Abraham, and his infertile wife Sarah. His name was
The modern version of surrogacy, which became available once in vitro
fertilization was possible, is gestational surrogacy. The surrogate is
implanted with an embryo and carries the child to term. The surrogate is
not the genetic mother. It is most often the embryo created by the
couple who retained the surrogate, but in many cases, the egg is a donor
egg. The child will have no genetic relationship to the surrogate. The
genetic mother may be either the “intentional” mother who arranged the
deal, or an anonymous egg donor.
Gestational surrogacy also opens up the whole realm of using designer
eggs as a possibility. Some clients simply want the best egg possible –
tall, intelligent, attractive – rather than a traditional surrogate’s
genetics. There is a huge market for premium eggs, which can be
purchased from large cryobanks or even online. This can create a
situation in which a child effectively has three mothers: an egg donor
mother, a surrogate mom who carried and gave birth to the baby, and an
intentional mother — the client in the contract.
