- hCG(Human Chorionic Gonadotropin)· Sexual Function & Hormones
- HCG is a hormone that acts like LH. It walks up to LH receptors on the testes or ovaries and tells them to keep producing sex hormones — even when the brain has stopped sending its normal signal.
What is it?
HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone naturally produced by the placenta during pregnancy. Structurally it closely mimics luteinizing hormone (LH) and binds the same LH receptor. It has long-standing approved clinical uses in fertility and testicular stimulation.
In plain English
HCG is a hormone that acts like LH. It walks up to LH receptors on the testes or ovaries and tells them to keep producing sex hormones — even when the brain has stopped sending its normal signal.
How it works
Binds LH receptors on Leydig cells in the testes (or theca cells in ovaries), driving testosterone production and supporting spermatogenesis indirectly. Its long half-life means dosing is much less frequent than Gonadorelin.
What researchers study
- •Hypogonadism research
- •Fertility and ovulation induction
- •Testicular preservation during androgen suppression studies
- •Comparison with Gonadorelin and Kisspeptin
- •Cryptorchidism research
What the internet talks about
HCG is the long-standing reference in TRT-adjacent communities and post-cycle research discussions. Threads compare it head-to-head with Gonadorelin on cost, half-life, and receptor desensitization risk.
