Gestational surrogacy refers to the process whereby one woman (the surrogate) serves to carry and deliver someone else’s (the biological mother’s) pregnancy. Typically, this is confined to use for women with an absent or abnormal uterus, or in whom medical conditions preclude pregnancy. In a gestational surrogacy arrangement, we use the IVF process to produce embryos from the biological mother’s eggs and her partner’s or donor sperm. The embryos are transferred into the uterus of the gestational surrogate where we hope one will implant and grow. The gestational surrogate carries the pregnancy and delivers the baby who then goes home with the biological parents. As we will see, the legal arrangements become an integral part of the process.
