Baerwald et al. (1) proposed a new model for ovarian follicular development in the human menstrual cycle. They showed additional waves of follicular development in the follicular and luteal phase of normal ovulatory cycles. Although no additional ovulation was observed, the authors speculated that the anovulatory follicles from the additional waves of follicular development may be able to ovulate in the presence of an additional LH surge.
