Clomiphene has mainly antiestrogenic effects and some estrogenic effects. The mechanism in stimulating ovulation is unknown but is believed to be related to its antiestrogenic properties. By clomiphene competing with estrogen for binding sites at the hypothalamic level, the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), secretion is increased, which results in ovarian follicle maturation, followed by the preovulatory LH surge, ovulation, and the subsequent development of the corpus luteum. Usefulness in male infertility is also likely related to the increases in FSH and LH secretion.
