Background
Human chorionic gonadotropin (HCG) is a glycoprotein hormone crucial in mammalian reproduction. Produced by trophoblast cells of the developing placenta after fertilization, it maintains the corpus luteum to sustain progesterone secretion for uterine endometrial maintenance. In research, HCG’s structure, receptor signaling mechanisms, and roles in early pregnancy regulation, trophoblast invasion, and pathological conditions like gestational trophoblastic disease are intensively studied, providing insights into reproductive biology and clinical diagnostics.
