hCG
Also known as: Human Chorionic Gonadotropin, Chorionic Gonadotropin, Pregnyl, Novarel, Ovidrel
Human chorionic gonadotropin is a placental glycoprotein hormone composed of a 92-amino-acid alpha subunit (shared with LH, FSH, and TSH) and a distinct 145-amino-acid beta subunit, joined non-covalently and heavily glycosylated. It acts as an agonist at the luteinizing hormone/choriogonadotropin receptor (LHCGR), mimicking the LH surge. In females it sustains the corpus luteum and progesterone production in early pregnancy and triggers final oocyte maturation and ovulation; in males it stimulates testicular Leydig cells to produce intratesticular testosterone, supporting spermatogenesis. hCG is FDA-approved (e.g., Pregnyl, Novarel, recombinant Ovidrel) for ovulation induction, assisted reproduction, and male hypogonadism/cryptorchidism.
