目的:探讨在IVF-ET中,启动日血清雌二醇水平对IVF-ET结局的评价意义。方法:分析采用黄体期长方案的78个IVF-ET周期,根据降调节后启动日血清雌二醇水平分为A组(0～5 pg/ml)、B组(5～20 pg/ml)和C组(>20pg/ml)。结果:各组间的Gn平均使用量、获卵数、MII卵子数及HCG日雌二醇水平比较差异无统计学意义(P>0.05)。A、B、C 3组的妊娠率分别为42.31%、51.23%和26.67%,但各组间比较差异无统计学意义(P>0.05)。结论:降调节后的血清雌二醇水平>20 pg/ml时IVF-ET妊娠率虽有明显下降,但差异无统计学意义(P>0.05),故降调节后血清雌二醇水平在达到降调标准后对IVF-ET结局没有预测价值。
Objective: To investigate the significance of serum estradiol level on the outcome of IVF-ET in IVF-ET. Methods: Seventy-eight IVF-ET cycles with long term luteal phase protocol were divided into group A (0 to 5 pg / ml) and group B (5 to 20 pg / ml) according to the serum estradiol level And group C (> 20 pg / ml). Results: The average amount of Gn, the number of oocytes retrieved, the number of MII oocytes and the estradiol level on HCG day were not significantly different between groups (P> 0.05). The pregnancy rates in groups A, B and C were 42.31%, 51.23% and 26.67%, respectively, but there was no significant difference among the groups (P> 0.05). CONCLUSION: Although the pregnancy rate of IVF-ET decreased significantly at the level of serum estradiol> 20 pg / ml, the difference was not statistically significant (P> 0.05), so the level of serum estradiol after the decrease was reached There is no predictive value for IVF-ET outcome after lowering the standard.
