Gestational Surrogacy
With gestational surrogacy, the surrogate's eggs are not used at all. Therefore, the child will not be related to the surrogate biologically. Using the gestational type of surrogacy, the embryo is actually created by using both biological father's sperm and the biological mother's egg or egg donor through a process called in vitro fertilization.
It is not until after the biological mother's egg or donor’s eggs are fertilized that the embryo is transferred to the uterus of the surrogate using the process of in vitro fertilization. In most cases, it will take between three and five days for the embryos to develop in the laboratory prior to transferring them to the surrogate. Then, once the embryo has successfully been placed into the surrogate's uterus, the surrogate will carry the embryo through the pregnancy term until its birth.
