What is clomiphene?
Clomiphene is a non-steroidal fertility medicine. It causes the pituitary gland to release hormones needed to stimulate ovulation (the release of an egg from the ovary).
Clomiphene is used to cause ovulation in women with certain medical conditions (such as polycystic ovary syndrome) that prevent naturally occurring ovulation.
Clomiphene may also be used for purposes not listed in this medication guide.
