Mechanisms & Repurposing/Chorionic gonadotropin (hCG)

Chorionic gonadotropin (hCG)

Binds LH/hCG receptors, stimulating Leydig-cell testosterone production and maintaining corpus luteum progesterone in labelled uses.

EndocrineReceptor agonism

Primary Mechanism of Action

Clinical / Scientific

hCG is a glycoprotein hormone activating the LHCGR. In men this drives testicular steroidogenesis; in women it mimics the LH surge / supports luteal progesterone. Urinary or recombinant pharmaceutical hCG is established; catalog vials must not be confused with a specific licensed presentation.

Pathway Targets

LH/hCG receptor

Scientific explanation

Gs- steroidogenic agonism.

In Plain Language

hCG is the pregnancy hormone that also looks like LH. In men it can tell the testes to make testosterone; in women it can mimic the ovulation LH signal.
