卵泡发育及预告排卵期的超声显像检测评价

Evaluation of Ultrasonography for Monitoring Follicles and Prediction of Ovulation

目的 探讨超声显像监测卵泡预告排卵期的价值。方法 应用超声显像对 46例 5 6个月经周期的卵泡发育与排卵进行了监测 ,其中自然排卵组 2 7例 3 4个周期 ,促排卵组 19例 2 2个周期性。结果 ①自然排卵组排卵前一天卵泡直径 ( 2 1± 1.2 1)mm ,卵泡平均每天增长 ( 1.9± 0 .3 6)mm ,以卵泡直径 2 0mm预测排卵的时间为 ( 1.3 1± 0 .47)天 ,排卵率占 91.1%。②促排卵组采用CC/HMG方案后 ,排卵前一天卵泡直径为 ( 2 3± 1.3 2 )mm ,卵泡平均每天增长 ( 2 .0± 0 .5 7)mm。以卵泡直径 2 3mm预测排卵时间为 ( 1.13± 0 .85 )天 ,排卵率达 81.8% ( 18/2 2 )。结论 应用超声显像监测卵泡的生长发育过程及预告排卵期 ,方法简便易行 ,结果准确可靠 ,对于临床诊断与治疗不孕症和 /或选择恰当的人工受精时机 ,具有极为重要的临床应用价值。

Objective To investigate the value of ultrasonography for monitoring follicles and predicting ovulation. Methods Sonography was performed on 56 cycles of 46 cases to monitor their ovarian follicular development and ovulation,including 34 natural and 22 stimulated cycles. Results The study showed that the mean growth increment of the follicles was ( 1.9 ±0.36)mm per day in natural cycles and (2.0±0.57)mm in stimulated cycles. The mean diameter of follicles on the preovulatory day was (21±1.2)mm and (23±1.32)mm respectively in the two groups. If the diameter 20mm and 23mm was regarded as nature follicle size, the predicting ovultory time was 1.13±0.17 days and 1.13±0.47 days, the ovulation rate was 91.1% and 81.8% in natural and stimulated groups respectively. Conclusion Sonography is an accurate and useful method for detecting and monitoring follicular development. It is of great value for clinical diagnosis and treatment for sterile women. [
