    Clomiphene is the drug of choice for first line treatment of anovulatory dysfunction (where the ovaries do not release an oocyte during the menstrual cycle) for a variety of reasons. It is orally administered, has few side effects, is easily available and is inexpensive. It acts as a selective estrogen receptor modulator to induce ovulation.
