Ovarian follicles in the immediate preovulatory period were measured with real-time or static ultrasound. Thirty-nine follicles were examined in thirty-six patients. In 29 spontaneous cycles the mean follicular diameter was 21.1 mm (range 17 to 25 mm) and the mean volume was 5.1 ml. In seven stimulated cycles the mean diameter was 18.4 mm and the mean volume was 3.5 ml. Laparoscopic needle aspiration of the follicular contents was performed within 12 hours of ultrasound examination in every case. Follicular dimensions based on the volume of aspirated fluid correlated well with the ultrasound measurements (r = 0.847; P < 0.001), which suggests that ultrasound is a useful technique for examining preovulatory follicular development.
在即将排卵前的时期，使用实时或静态超声测量卵巢卵泡。对36例患者的39个卵泡进行了检查。在29个自然周期中，卵泡平均直径为21.1毫米（范围为17至25毫米），平均体积为5.1毫升。在7个促排卵周期中，平均直径为18.4毫米，平均体积为3.5毫升。在每例超声检查后的12小时内，通过腹腔镜对卵泡内容物进行穿刺抽吸。根据抽吸液体积得出的卵泡尺寸与超声测量结果具有良好的相关性（r = 0.847；P < 0.001），这表明超声是检查排卵前卵泡发育的一种有用技术。
