2、的胚胎复苏效果及临床结局。结果:D2i>4一细胞组的胚胎复苏率和卵裂球全存活率显著高于D2<4一细胞组(89.35%vs.79.11%,42.01%30.22%,P<0.05);D3≥6-细胞组的胚胎复苏率和卵裂球全存活率显著高于D3<6一细胞组(86.52%72.43%,41.13%吼31.07%,P<0.叭)。D2组冷冻胚胎复苏后的优质胚胎率(56.84%)高于D3组(48.82%),但D3组FETI~床妊娠率(38.52%)高于D2组(27.61%),差异均有统计学意义(P<0.05),2组间胚胎复苏率和流产率差异无
3、统计学意义(83.50%vs.79.44%,10.81%vs.10.09%,P>O.05)。随着移植优质胚胎数的增加,临床妊娠率和多胎率增加,差异有统计学意义(P~4一细胞和D3≥6一细胞的胚胎冻融效果较好,D3冷冻胚胎的FETf~床结局优于D2冷冻胚胎。【关键词】胚胎冷冻;冻融胚胎移植;复苏率;妊娠率ImpactofEmbryoBlastomereNumberandD2orD3Cry0preservatiOnafterinVitroFertilizationontheClinicalOutcom
