The Claim

Clomiphene citrate therapy in men with idiopathic infertility is associated with a doubling of serum testosterone levels (from 10.05 to 19.90 nmol/L) and significant increases in luteinizing hormone and follicle-stimulating hormone, consistent with its mechanism of blocking estrogen feedback at the hypothalamus to stimulate gonadotropin release.

How it works
1 study reviewed
In plain English

In men with unexplained infertility, clomiphene citrate treatment increases serum testosterone levels by approximately 100% and raises levels of luteinizing hormone and follicle-stimulating hormone through inhibition of estrogen signaling in the hypothalamus.

See the scientific wording

Clomiphene citrate therapy in men with idiopathic infertility is associated with a doubling of serum testosterone levels (from 10.05 to 19.90 nmol/L) and significant increases in luteinizing hormone and follicle-stimulating hormone, consistent with its mechanism of blocking estrogen feedback at the hypothalamus to stimulate gonadotropin release.

Why this might work

Clomiphene citrate binds to estrogen receptors in the brain, preventing estrogen from signaling that testosterone levels are high. This tricks the brain into releasing more signals that tell the pituitary gland to release hormones that stimulate the testes. The testes respond by producing more testosterone and sperm.

  1. Study: Effectiveness of clomiphene citrate on total motile sperm count and hormonal profile in men with clinical infertility.

    This study found that taking clomiphene made men’s bodies produce more of the hormones that tell the testes to make testosterone and sperm — exactly what scientists expected it to do. It didn’t work the same for everyone, but on average, it worked as predicted.
