hyperovulation

Hyperovulation in humans refers to the production and release of more than one egg during a menstrual cycle. Hyperovulation can occur naturally or be stimulated via hormone treatments for the purposes of egg donation in third-party reproduction. Under normal conditions, when more than one egg is released, the chances of conceiving fraternal twins or triplets is increased. Stimulated hyperovulation involves several drugs and the careful monitoring of hormone levels and ovarian status using an ultrasound. Once mature, follicles are punctured during the egg retrieval procedure and evaluated for quality before being used for in vitro fertilization (IVF).
