Clomiphene is used as a fertility medicine in some women who are unable to become pregnant. It probably works by changing the hormone balance of the body. In women, this causes ovulation to occur and prepares the body for pregnancy. Clomiphene may also be used for other conditions in both females and males as determined by your doctor. Available only with your doctor's prescription.
