Human chorionic gonadotropin (hCG) contains a hormone called Human Chorionic Gonadotropin (HCG), which is also produced naturally by the body. It is used in women, who have a problem with ovulation (release of an egg). It is also used along with other fertility medicines, to help produce eggs in women who are undergoing assisted reproductive technology (ART) procedures such as in-vitro fertilization (IVF). In males, it is used to treat conditions like delayed puberty, and low sperm cell count.
