What is clomiphene (Clomid)?
Clomiphene is a selective estrogen receptor modulator (SERM) that blocks estrogen feedback at the pituitary gland, signaling the body to produce more testosterone; it is sometimes prescribed off-label to treat low testosterone in men.
Clomiphene, marketed as Clomid, is a selective estrogen receptor modulator (SERM) that works by blocking estrogen receptors in the pituitary gland. This action tricks the body into thinking estrogen levels are low, which triggers the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones then signal the testes to increase natural testosterone production.
Originally developed and FDA-approved for treating female infertility, clomiphene is frequently prescribed off-label by healthcare providers to address low testosterone (hypogonadism) in men. Unlike testosterone replacement therapy, which supplies exogenous hormone directly, clomiphene stimulates the body's own testosterone production. This distinction appeals to men who wish to maintain natural hormonal production or preserve fertility, since direct testosterone replacement can suppress the body's endogenous testosterone synthesis and reduce sperm count.
Clomiphene is typically taken orally in tablet form. Dosing and duration vary based on baseline testosterone levels and individual response. Because it works by stimulating the body's own hormone production rather than replacing it externally, clomiphene may be considered when testosterone replacement therapy providers evaluate treatment options for low testosterone. Side effects can include visual disturbances, mood changes, and hot flashes, and regular monitoring through blood work is standard practice.
