Clomiphene citrate is the most commonly used fertility medication prescribed for anovulatory women.
Clomiphene is very effective in inducing ovulation in most women, however, pregnancy rates only approach 65 percent with the use of this medication. Thus, the lack of ovulation is not always the only cause of infertility. Over 75 percent of patients who get pregnant with clomiphene do so within the first four to six months. Thus, if a pregnancy not is not achieved within the first four to six months of use, additional evaluations and therapies are usually required. A clearly defined period of use is advisable secondary to potential risks associated with clomiphene citrateuse.
