What is enclomiphene?

Enclomiphene is one of two active isomers found in clomiphene citrate, a selective estrogen receptor modulator (SERM) originally developed for fertility treatment. Unlike exogenous testosterone injection, which suppresses the body's natural hormone production, enclomiphene works by blocking estrogen feedback at the pituitary gland, triggering increased secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This cascade stimulates the testes to produce testosterone endogenously.

The distinction matters because clomiphene citrate contains both enclomiphene and zuclomiphene (a weaker isomer with a longer half-life). Enclomiphene acts quickly and clears faster, making it the primary driver of testosterone elevation. For men seeking testosterone support without the shutdown of endogenous production that comes with traditional TRT, enclomiphene offers an option that preserves fertility and natural hormone signaling.

In Florida telehealth and in-clinic practices specializing in hormone optimization, enclomiphene is prescribed as a tablet or capsule, typically dosed between 12.5 mg and 25 mg daily. It appeals to patients who want to avoid injections or maintain their body's own production capacity. Fertility and urology providers in Florida often discuss enclomiphene alongside other hormone-support strategies when tailoring treatment to individual health goals and lab markers.
