Overview
Human Menopausal Gonadotropin (HMG) is a potent hormonal compound traditionally extracted from the purified urine of postmenopausal women. It is distinct for containing both Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) in roughly equal proportions. By providing these essential gonadotropins exogenously, HMG acts directly on the testes in men and ovaries in women — supplying the downstream hormones the pituitary would normally secrete — making it a cornerstone in reproductive medicine and endocrine research.
In clinical and research settings, HMG is primarily utilized to address infertility caused by hormonal deficiencies. For male subjects, it promotes sperm development and testosterone synthesis, while in females, it facilitates follicle growth and ovulation. Beyond fertility, it serves as a critical tool for studying the hypothalamic–pituitary–gonadal (HPG) axis and systemic hormonal regulation. Unlike HMG-CoA inhibitors (statins), this peptide is strictly related to reproductive biochemistry rather than cholesterol management.
Mechanism of action
It acts as an exogenous source of FSH and LH, directly stimulating the gonads to produce sex hormones and mature gametes.
