Enclomiphene is a nonsteroidal selective estrogen receptor modulator (SERM) that may help men with secondary hypogonadism increase their body's natural testosterone production. It works by increasing LH and FSH, which stimulate the testes to produce more testosterone and may help support sperm production.
It is different from testosterone replacement because it stimulates the body's own hormone production rather than directly supplying testosterone. However, enclomiphene is not FDA-approved in the U.S., and its clinical benefits and long-term safety require medical evaluation
