Human Chorionic Gonadotropin (hCG)
Human Chorionic Gonadotropins (hCG) is a commercially available hormone that controls reproductive function and is used for the treatment of infertility. It is derived from two sources: biological (urine-based) or manufactured (recombinant). Urine-based products have been used to enhance fertility for over thirty years. HCG helps to mature eggs and stimulate ovulation.
