What is HCG?
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone produced by the placental syncytiotrophoblast cells during pregnancy. Structurally, HCG is a heterodimeric protein consisting of an alpha subunit (identical to LH, FSH, and TSH) and a unique beta subunit that confers HCG-specific biological activity. HCG exhibits potent luteinizing hormone (LH) mimetic properties by binding to and activating the LH/CG receptor (LHCGR) on Leydig cells in testes and theca/luteal cells in ovaries. In males, HCG stimulation triggers testosterone biosynthesis through upregulation of steroidogenic enzymes (StAR, CYP11A1, CYP17A1, 17β-HSD). In females, HCG maintains corpus luteum progesterone production to support early pregnancy. The hormone’s longer half-life (24-36 hours) compared to LH (20 minutes) makes it valuable for sustained receptor activation research. Purified HCG is extracted from pregnant women’s urine and extensively used in reproductive endocrinology research.
