It varies: It stimulates the release of hormones needed to cause ovulation. Clomiphene therapy is typically used for 5 consecutive days early in the menstrual cycle, for 3 to 6 monthly cycles. It may take several cycles to find the right dose to stimulate ovulation. After that dose is determined, a woman will take the drug for at least 3 more cycles. If there is no pregnancy after 6 cycles, it may not work.
