HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone produced during pregnancy, widely used in research for studies of the hypothalamic-pituitary-gonadal (HPG) axis, testicular function, and reproductive endocrinology. Structurally similar to LH, HCG acts on LH receptors to stimulate testosterone and progesterone production in research models.
