Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone naturally produced by the syncytiotrophoblast cells of the placenta following implantation. Comprising an alpha subunit shared with LH, FSH, and TSH, and a unique beta subunit that confers its biological specificity, HCG binds to the luteinising hormone/choriogonadotropin receptor (LHCGR) and activates downstream cAMP-mediated signalling pathways.
In research settings, HCG is widely investigated for its role in stimulating gonadal steroidogenesis, including testosterone production in Leydig cells and progesterone synthesis in the corpus luteum. It is a key tool in reproductive endocrinology studies, fertility research, and investigations into hypothalamic-pituitary-gonadal (HPG) axis modulation.
