Experts at surrogacy clinics in Chennai perform surrogacy procedures by first performing the IVF procedure. They collect the birth parents' eggs and sperm and fertilize them in an IVF lab until an embryo is formed. Once fertilization occurs, the embryo specialist selects the healthiest embryos and transfers them into the surrogate mother's womb in Chennai to confirm successful conception. On the 14th day after the embryo/s transfer, the biological parents and the surrogate mother have to visit the surrogacy clinic in Chennai for a successful pregnancy test. A specialist from the clinic will perform an ultrasound examination to hear the heartbeat of a small child. Once the specialist finds that the heartbeat is normal, she discharges the surrogate mother and biological parents from surrogacy clinics in Chennai. After discharge from the fertility clinic, the genetic parents have to take the surrogate mother in Chennai to a local gynaecologist for further pregnancy procedures.
