摘要 目的 :探讨影响常规体外受精(in vitro fertilization,IVF)与卵胞浆内单精子显微注射(intracytoplasmic sperm injection,ICSI)治疗周期中剩余胚胎体外培养囊胚形成潜力的相关因素,为单囊胚移植打下基础。方法 :将IVF/ICSI治疗周期中第3天(D3)卵裂期胚胎移植和冷冻后剩余的优质/非优质胚胎行囊胚培养,观察囊胚形成率。比较患者的年龄、病因、受精方式、D3胚胎质量、卵裂球数和碎片量与囊胚形成率的关系,并比较囊胚形成情况与体外受精临床妊娠率的影响。结果:(1)70个治疗周期中303枚剩余胚胎进行囊胚培养,形成囊胚127枚(41.91%),其中优质囊胚56枚(44.09%);(2)不同年龄、病因、受精方式对囊胚形成率的影响差异均无统计学意义(均P>0.05);(3)D3胚胎碎片>25%、卵裂球数<7个的胚胎囊胚形成率明显降低;(4)剩余胚胎有囊胚形成周期与无囊胚形成周期的临床妊娠率比较差异无统计学意义(P>0.05)。结论:将移植、冷冻后剩余胚胎进行体外囊胚培养,可以筛选出具有发育潜能的胚胎,提高治疗周期胚胎的利用率。
