HMG (Human Menopausal Gonadotropin) is the fertility peptide that does what HCG can't — it provides both LH and FSH activity, making it the most complete reproductive hormone analog available in research.
While HCG only mimics LH, HMG delivers the dual action that both the testosterone-producing Leydig cells and the sperm-producing Sertoli cells need. For comprehensive fertility research, HMG is the missing piece.
What is HMG?
HMG, also known as menotropin, is extracted from the urine of postmenopausal women. It contains approximately equal amounts of two key gonadotropins: luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
The reason postmenopausal urine is the source is elegant — after menopause, the ovaries stop responding to LH and FSH, so these hormones accumulate in the blood and are excreted at high concentrations. Nature's own supply chain.
How HMG Works
HMG provides a two-pronged approach to reproductive stimulation:
- LH component: Stimulates Leydig cells in the testes to produce testosterone — same as HCG
- FSH component: Stimulates Sertoli cells to support spermatogenesis — this is what HCG cannot do
It's the FSH component that makes HMG unique. FSH is essential for sperm production — without it, Sertoli cells can't support the maturation of sperm. HCG alone can't restore sperm production because it has no FSH activity.
Fertility Restoration Research
HMG has been used in fertility research for decades. Key applications include:
- Male fertility restoration: Combined with HCG, HMG can restore spermatogenesis in men with severe fertility issues
- Female ovulation induction: Stimulates follicle development in women who don't ovulate regularly
- IVF protocols: Used to stimulate multiple follicle development for in vitro fertilization
- Post-cycle recovery: Research explores HMG + HCG combinations to restore full HPG axis function
HMG vs HCG: The Critical Difference
| Feature | HMG | HCG |
|---|---|---|
| Hormones provided | LH + FSH | LH only |
| Sperm production | ✅ Yes (FSH) | ❌ No |
| Testosterone | ✅ Yes (LH) | ✅ Yes (LH) |
| Best for | Fertility + testosterone | Testosterone only |
Key insight: HMG is the only compound that provides both LH and FSH activity. For fertility research where sperm production matters, HMG is essential — HCG alone won't restore spermatogenesis.
Combination Protocols
In research settings, HMG is often combined with HCG for comprehensive reproductive hormone restoration. The HCG handles the testosterone side while HMG's FSH component handles sperm production. Some protocols also add gonadorelin to restart the entire HPG axis from the top down.
This combination approach — gonadorelin (brain) → HCG (Leydig cells) + HMG (Sertoli cells) — covers every level of the reproductive system, from signaling to production.
The Bottom Line
HMG is the fertility peptide that completes the picture. While HCG handles testosterone, HMG adds the critical FSH component needed for sperm production. For any research involving comprehensive reproductive restoration, HMG is essential.

Quick answers on legality, purchasing, and research use.
Is HMG legal to buy in the US?
Yes. HMG is legal to purchase for laboratory research use in the United States and most of Europe. Research compounds are sold with a 'not for human consumption' label, which is the standard structure of the research peptide market.
Do you need a prescription to buy HMG?
No. HMG is sold for research use only, not as a prescription drug, so no prescription is required to purchase it. The research-use label is what separates it from regulated pharmaceutical products.
