Ovulation induction

Ovulation induction is the stimulation of ovulation by medication. It is usually used in the sense of stimulation of the development of ovarian follicles to reverse anovulation or oligoovulation, but can also be used in the sense of triggering oocyte release from relatively mature ovarian follicles. In any case, ovarian stimulation (in the sense of stimulating the development of oocytes) is often used in conjunction with ("strict") ovulation induction. Also, a few definitions also include controlled ovarian hyperstimulation (stimulating the development of multiple follicles of the ovaries in one single cycle) in the definition of ovarian stimulation. Otherwise, ovarian hyperstimulation may still be a side effect of ovulation induction.
