Rather than supplying testosterone directly, enclomiphene works upstream — blocking estrogen receptors in the hypothalamus and pituitary. This interrupts estrogen's negative feedback signal, prompting the body to release more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn stimulates the testes to produce more of their own testosterone.

• Male fertility preservation protocols
• Off-label secondary hypogonadism management
• Research settings studying HPG-axis stimulation

• Non-steroidal — chemically unrelated to testosterone itself
• Preserves natural testicular function and fertility, unlike exogenous testosterone
• Sibling compound to zuclomiphene (the cis-isomer, largely inactive/estrogenic) — enclomiphene is the isolated, more selective half of clomiphene citrate
