title: Ovum retention in the human.
abstract: Two cases of ovum retention occurring in postovulatory follicles are described. The ova were recovered at laparoscopy by aspiration of decompressed ovulatory follicles, one during a natural cycle and the other following a programmed clomiphene/human chorionic gonadotropin cycle. Each patient had a normal luteal phase with an increased progesterone level indicative of ovulation. The implications of these findings and their relevance to human fertility studies are discussed.
