HMG is one of the most extensively studied gonadotropin preparations in reproductive endocrinology research, with well-characterised pharmacological profiles for both FSH and LH receptor activation. It serves as a research tool for investigating gonadotropin-mediated signalling in the hypothalamic-pituitary-gonadal (HPG) axis, folliculogenesis, steroidogenesis, and spermatogenesis in preclinical models.\u003c\/p\u003e\u003ch3\u003eMechanism of Action\u003c\/h3\u003e\u003cp\u003eHMG exerts its biological effects through the combined action of its FSH and LH components, each acting on distinct G-protein-coupled receptors (GPCRs) in gonadal tissue. FSH binds to the FSH receptor (FSHR) on granulosa cells (female) and Sertoli cells (male), activating Gs-mediated adenylyl cyclase and cAMP\/PKA signalling to promote follicular development, aromatase expression, and oestrogen synthesis in females, and to support spermatogenesis and inhibin B production in males. LH binds to the LH receptor (LHR) on theca cells (female) and Leydig cells (male), stimulating androgen synthesis via the cAMP\/PKA\/StAR pathway — driving testosterone production in males and androstenedione synthesis (for aromatisation to oestradiol) in females. Together, FSH and LH activity in HMG recapitulates the endogenous gonadotropin milieu required for gonadal function, making it a valuable tool for studying HPG axis pharmacology and reproductive biology.\u003c\/p\u003e\u003ch3\u003eResearch Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFSH receptor (FSHR) and LH receptor (LHR) pharmacology and gonadotropin signalling studies\u003c\/li\u003e\n\u003cli\u003eFolliculogenesis, granulosa cell biology, and ovarian steroidogenesis research\u003c\/li\u003e\n\u003cli\u003eSpermatogenesis, Sertoli cell function, and male reproductive biology investigation\u003c\/li\u003e\n\u003cli\u003eHPG axis regulation, gonadotropin feedback, and reproductive neuroendocrinology research\u003c\/li\u003e\n\u003cli\u003eHypogonadotrophic hypogonadism and fertility disorder preclinical models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Formula:\u003c\/strong\u003e Glycoprotein hormone (FSH + LH, ~1:1 ratio)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e ~34 kDa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 9002-68-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥95%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Lyophilised powder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e -20°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShelf Life:\u003c\/strong\u003e 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eThis product is intended for legitimate laboratory and analytical research use only.
