Superovulation is the release of many mature eggs in one menstrual cycle. This often occurs after taking a medicine that stimulates the ovaries. Medicines that may be used are clomiphene or gonadotropins, such as a follicle-stimulating hormone (FSH).

Superovulation with medicines 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.
