摘要 目的探讨胚胎碎片出现时间对体外受精-胚胎移植(IVF/ICSI-ET)妊娠结局的预测价值。方法回顾性分析225个黄体期长方案促排225个周期中1 658枚胚胎碎片出现时间,分为3组,即A组受精后24~25 h胚胎有早期卵裂伴有碎片,B组受精后24~25 h有早期卵裂不伴胚胎碎片,C组受精后48 h出现分裂。比较各组在第3天的优胚率、囊胚形成率、着床率及临床妊娠率。结果 A组的优胚率、临床妊娠率、均明显低于B、C2组(34.00%与79.18%及55.14%,31.15%与64.94%及56.58%,P<0.05)。A组囊胚形成率和着床率低于其他2组,但差异无统计学意义;B组第3天的优胚率、囊胚形成率、着床率、临床妊娠率均高于C组,但差异无统计学意义。结论胚胎碎片出现的时间是一项对胚胎质量进行评估的有效补充,对选择优质胚胎进行移植、提高IVF/ICSI-ET治疗的临床妊娠率有一定的帮助。
