Ovulation induction

In the woman with anovulation and polycystic ovarian syndrome, there are many options for ovulation induction. Treatment should be individualized, but clomiphene citrate is an excellent first-line agent. In the woman resistant to clomiphene citrate, combination therapy often results in pregnancy. Some women with PCOS only respond to gonadotropin therapy. These women are at a higher risk for multiple pregnancy and ovarian hyperstimulation syndrome. In the woman with anovulation and hypothalamic amenorrhea, the options for ovulation induction are limited. The luteal phase must be supported. The hypothalamus is unable to support the corpus luteum or early pregnancy.
