Enclomiphene Citrate is a selective estrogen receptor modulator (SERM) prescribed to support natural testosterone production in men with secondary hypogonadism — a condition where the brain fails to send adequate signaling to the testes, resulting in low testosterone despite healthy testicular function.
Unlike exogenous testosterone therapy, enclomiphene works upstream in the hormonal cascade. By blocking estrogen receptors in the hypothalamus and pituitary gland, it prompts the brain to increase its own output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) — the two hormones responsible for driving the testes to produce testosterone naturally. The result is elevated testosterone through the body’s own mechanisms rather than through external hormone introduction.
This makes enclomiphene a preferred option for men who want to address low testosterone while maintaining fertility, avoiding testicular suppression, or exploring alternatives to traditional TRT.
Clinical Applications
- Secondary hypogonadism
- Low testosterone with fertility preservation goals
- Natural testosterone optimization without exogenous hormones
- Alternative or transition therapy for men coming off TRT
How It Works Enclomiphene selectively blocks estrogen’s negative feedback signal at the pituitary and hypothalamus, triggering increased LH and FSH release. This cascade stimulates the testes to produce more testosterone endogenously — maintaining the natural hormonal axis rather than bypassing it.
