Abstract: 目的:探讨体外受精-胚胎移植(IVF-ET)中hCG注射日前后血清雌孕激素水平变化及其比值对妊娠结局的影响.方法:选取行短方案治疗的137例不孕症患者的临床资料,根据hCG注射日每成熟卵泡(B超下直径≥14mm的卵泡)的E2水平分为3组,A1组E2水平<450 pg/ml,A2组E2水平450~600 pg/ml,A3组E2水平>600 pg/ml;据hCG注射日较前一日E2增幅程度不同亦分为3组,B1组增幅程度<20%,B2组增幅程度20%~30%,B3组增幅程度>30%;另外为探讨hCG注射日雌、孕激素比值对妊娠结局的影响,按hCG注射日E2/P值不同亦分为3组,C1组E2/P<3,C2组E2/P=3~5,C3组E2/P>5;对上述3组的临床资料进行回顾性分析.结果:A2组的临床妊娠率高于A3组,A1和A2组的胚胎种植率亦高于A3组,差异均有统计学意义(P<0.05); B1组的临床妊娠率明显高于B2和B3组,B1组的胚胎种植率亦高于B3组,差异均有统计学意义(P<0.05); C3组的临床妊娠率高于C1组,差异有统计学意义(P<0.05); C2、C3组的胚胎种植率明显高于C1组,差异有统计学意义(P<0.05).结论:行IVF-ET患者的hCG注射日前后适合水平的血清雌、孕激素及其比值(E2水平在450~600 pg/ml,hCG注射日前后E2增幅<20%及E2/P>5)能获得较好的妊娠结局.
