摘　　要：目的探讨体外受精-胚胎移植(IVF-ET)中胚胎碎片对临床妊娠率及种植率的影响。方法观察246例行IVF-ET或卵母细胞浆内单精子注射病人胚胎碎片与临床妊娠率的关系。结果与正常和轻度碎片的胚胎相比,严重碎片(>50%)胚胎的临床妊娠率和种植率均明显降低(χ2=10.112、9.510,P<0.05),多胎妊娠率差异无显著性。结论提高胚胎质量,减少移植胚胎数量,有助于提高IVF-ET的成功率。Objective To observe the impact of embryo fragmentations on pregnancy. Methods Relationship between homogeneous embryo fragmentations with pregnancy rate was retrospectively analyzed among women underwent in vitro fertilization （IVF） or intracytoplasmic sperm injection （ICSI）. Results Massive embryo fragmentations and number of embryos per transfer significantly influenced the pregnancy and implantation rate. Conclusion Better quality of embryo and less number of embryos per transfer are important in increasing the pregnancy rate in IVF.
