摘　　要：目的探讨非优质胚胎在体外受精-胚胎移植中的冷冻价值。方法回顾性分析116例非优质胚胎冷冻移植周期。根据结局分为妊娠组与非妊娠组,比较两组中不同发育速度,均匀度以及碎片比例的胚胎所占比例。结果妊娠组中,卵裂球大小严重不均和碎片比例>20%的胚胎比例显著低于非妊娠组,碎片0-20%的胚胎比例则显著高于非妊娠组。卵裂球大小均匀或明显不均,以及不同发育速度的胚胎比例,二者并无显著差异。结论选择性冷冻非优质胚胎,有助于提高体外受精-胚胎移植的累积妊娠率,改善临床治疗结局。Objective ： To investigate the clinica vaule of frozen - thawed non - top quality embryo transfer. Methods ： One hundred and sixty frozen - thawed cycles were analized retrospectively, all embryos were divided into two groups by the result： pregnancy and unpregnancy. Analysis the difference of composition ratio of the parameter grade of embryo between pregnancy embryo and unpregnancy embryo. Results ： In non - top quality embryo, the embryo with serious unequally sized blastomeres or 〉 20% ratio of fragment in pregnancy embryo is lower than in nnpregnancy embryo, the embryo with 0 - 20% ratio of fragment in prignancy embryo is higher than in unpregancy embryo. Conclusion. It will be helpful to select frozen - thawed non - top quality embryo for the result of IVF -ET
