In gestational surrogacy, a woman carries a genetically unrelated offspring for another couple or a single individual who will be the intended parents of the child. Gestational surrogacy is possible due to the advancement of assisted reproductive technology (ART). IVF process is a type of ART used in the gestational surrogacy process, in which oocytes collected from the intended mother is fertilized with sperm collected from intended father in the laboratory and the formed embryo is transferred to the uterus of the gestational carrier for further development of the offspring. After completion of the full term, gestational surrogate delivers a child with no genetically related to her. In the case of infertility issues, egg donor or sperm donor helps are taken for embryo transfer.
The first reported successful pregnancy through gestational surrogacy was in 1985 and since then gradually this process is applicable for parents who unable to carry their generically related off-spring due to infertility or parents, who have a tricky situation to deliver a child, like homosexual couples, transgender person or single parent. Gestational surrogacy is only possible due to the advancement of ART. The rate of implantation is higher in gestational surrogacy among different types of embryo transfer.
