What is HCG??

Human Chorionic Gonadotropin (hCG, CAS 9002-61-3) is a heterodimeric glycoprotein hormone (MW ~36.7 kDa; α-subunit shared with LH/FSH/TSH, unique β-subunit) produced by syncytiotrophoblasts. hCG binds the luteinising hormone/choriogonadotropin receptor (LHCGR) with high affinity — activating Gs/adenylate cyclase → cAMP → PKA signalling — stimulating steroidogenesis in Leydig cells (testosterone production) and in corpus luteum (progesterone maintenance). It is the fundamental tool for studying LH receptor biology, gonadal steroidogenesis, and pituitary-gonadal axis function.

Research Applications

Leydig Cell Steroidogenesis

LHCGR activation, testosterone biosynthesis, StAR/CYP11A1/CYP17A1 enzyme expression

LH Receptor Biology

cAMP/PKA signalling, receptor internalisation, LHCGR desensitisation kinetics

Corpus Luteum Function

Progesterone maintenance, luteal phase studies, luteolysis prevention models

Male Reproductive Research

Testicular descent, Leydig cell function, spermatogenesis support in hypogonadism models

HPG Axis Studies

Hypothalamic-pituitary-gonadal axis, LH receptor cross-reactivity with FSH-α subunit research
