Biochem/physiol Actions

Two-chain glycoprotein hormone; the α-chain is identical to that of chorionic gonadotropin, TSH, and FSH, while biological specificity is attributed to the distinct β-chain. Induces ovulation, spermatogenesis, and synthesis of steroid sex hormones. Activity is mediated through a trans-membrane LH/chorionic gonadotropin receptor that is a member of the G-protein coupled receptor (GPCR) family.
