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

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

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