/HMG_HUMAN_MENOPAUSAL_GONADOTROPIN
Peptide Hormone

HMG (Human Menopausal Gonadotropin)

Gonadotropin (FSH/LH blend)

/HALF_LIFE
Approximate: FSH activity ~24–36 hours; LH activity ~10–20 hours (route- and product-dependent).
/DELIVERY
Subcutaneous or intramuscular injection

/WHAT_IT_IS

HMG, also called menotropins, provides both follicle-stimulating hormone (FSH) and luteinizing hormone (LH) bioactivity. In research settings, it’s used to study gametogenesis and steroidogenesis by directly stimulating gonadal FSHR and LHCGR pathways.

/USAGE

Investigated for inducing follicular development, supporting spermatogenesis, and modeling endocrine feedback in the hypothalamic–pituitary–gonadal (HPG) axis.

/MECHANISM_OF_ACTION

FSH component activates FSH receptors in gonadal tissue to promote follicular growth and Sertoli-cell–mediated spermatogenesis. LH component activates LH/CG receptors to stimulate theca/Leydig cell steroidogenesis (estradiol/testosterone).

Reported Benefits

  • +Stimulates follicular development (ovary)
  • +Supports spermatogenesis (testis)
  • +Increases gonadal steroid production
  • +Useful for HPG-axis functional studies

Reported Side Effects

  • Injection-site pain or redness
  • Abdominal discomfort/bloating
  • Headache or mood changes
  • Fluid retention
  • Gynecomastia (males)
  • Ovarian hyperstimulation–like effects in susceptible models

/STACKED_WITH

hCG (chorionic gonadotropin)Follitropin alfa/beta (rFSH)GnRH agonist/antagonistAromatase inhibitor (research use to modulate estrogen feedback)

/RESEARCH_NOTES

Potency and LH bioactivity vary by preparation; many modern lots derive LH activity via hCG content. Monitoring estradiol/testosterone and ultrasound/gonadal metrics is common in controlled studies.
