Studies & key findings
- hCG, a glycoprotein hormone with full LH-receptor agonism, has been FDA-approved since 1939 for cryptorchidism and hypogonadotropic hypogonadism; it stimulates Leydig cell testosterone synthesis and seminiferous tubule spermatogenesis, serving as the pharmacological substitute for LH in men with secondary hypogonadal infertility.
- A randomized double-blind study showed that adding low-dose hCG (250–500 IU every other day) to testosterone replacement therapy limits the decline in intratesticular testosterone to only 7% (vs. 94% decline with TRT alone) and prevents the azoospermia that typically develops within 10 weeks of TRT — the principal clinical use case for hCG co-administration.
