摘要 目的:研究囊胚期胚胎培养与移植对体外受精-胚胎移植(IVF-ET)妊娠结局的影响。方法:将行常规IVF-ET助孕的80个周期,常规取卵、受精后随机分为卵裂期胚胎移植和囊胚期胚胎移植两组,每组各40例,卵裂期胚胎移植组第2天或第3天进行胚胎移植,囊胚期胚胎移植组采用Quinn's培养基序贯培养,第5天或第6天行至少1个3期以上囊胚移植,比较两组获卵数、受精率、卵裂率、平均胚胎植入数及妊娠率的差异。结果:两组获卵数和受精率无明显差异;两组平均胚胎植入数分别为(2.43±0.54)枚和(1.52±0.47)枚、生化妊娠率分别为60.0%和47.5%、临床妊娠率分别为52.5%和30.0%,平均移植胚胎数和妊娠率两组比较均有显著性差异(P<0.05)。结论:囊胚期胚胎移植组移植较少的胚胎即可获得较高的妊娠率,采用囊胚期胚胎移植可明显提高IVF-ET妊娠率,并可降低胚胎植入数,从而减少多胎率的发生。
