Ovarian follicles during oral contraceptive cycles: their potential for ovulation.
Ovarian follicles of a preovulatory size were encouraged to develop by extending the pill-free period of combine, triphasic oral contraceptive (OC) cycles. Despite recommencement of OC therapy, most follicles continued to grow and then respond to gonadotropin administration by both rupture and luteinization. It is concluded that follicles developing during OC cycles have the potential for ovulation, but this is of doubtful clinical significance for the vast majority of women.
