Superovulation is the production of many mature eggs in one menstrual cycle, usually triggered by a medication that stimulates the ovaries. Such medications include clomiphene, follicle-stimulating hormone (FSH), and gonadotropins.

Superovulation with gonadotropins or FSH is monitored closely to prevent severe ovarian hyperstimulation, a potentially life-threatening condition.

While superovulation increases the likelihood of conception, it also increases the risk of becoming pregnant with more than one fetus, such as twins or triplets.
