预测排卵相关因素的探讨

Analysis of Correlative Factors in Predicting Ovulation

目的 研究排卵与相关因素的关系 ,寻找预测排卵的简便、切实可行的指标。方法 用 B超连续监测 2 35个周期的卵泡发育及子宫内膜厚度 ,在卵泡直径≥ 16 mm,用酶联免疫吸附法测定 L H峰 ,并进行宫颈粘液评分及阴道脱落细胞成熟度的测定 ,以放免法测定血雌二醇及孕酮的含量。结果 促排卵组在排卵前卵泡直径明显大于自然排卵组 ,差异有显著性 (P<0 .0 5 ) ,而子宫内膜厚度无差异。L H峰出现后 72 h内排卵者 2 2 7例 (96 .4%) ,自然排卵组排卵前CS评分≥ 8分者 91例 (91.92 %)。MI值在排卵前 1天平均为 0 / 9/ 91。结论 B超监测卵泡发育及 L H峰测定是预测排卵的简便、切实可行的指标。

Objective To search convenient and practicable indexes in predicting ovulation by analyzing the relationship between ovulation and its correlative factors.Method Follicular diameters and endometrial thickness had been monitored continuously for 235 cycles by B ultrasonic.LH peaks were determined by ELISA once the follicular diameters were not less than 16 mm and at the same time CS and MI were assayed.Blood Estradiol and Progesterone were determined by RIA.Results Before ovulation, follicular diameters of induced ovulation group were significantly bigger than those of natural ovulation group (P<0.05),while there were no significant difference between endometrial thickness of the two groups.Ovulations occured in 227 cases(96.40%) within 72 hours after appearance of LH peaks.CS of 91 cases were over 8 before ovulation in natural ovulation group(91.92%).MI were 0/9/91 on average one day before ovulations.Conclusion B ultrasonic surveillance on follicular development and LH peak were convenient and practicable indexes in predicting ovulation.
