碎片是体外受精(in vitro fertilization,IVF)-胚胎培养过程中的常见现象。碎片的产生可能与细胞凋亡、基因、女性年龄、卵母细胞数量、单精子显微注射技术等有关,虽然碎片的产生是胚胎发育过程的一个特征还是辅助生殖技术及其体外受精-体外培养引起的不良影响没有确切报道,但是碎片的产生对早期胚胎发育潜能、移植胚胎的种植率、临床妊娠率和产科结局等有一定影响,目前碎片的多少和分布特征仍是人胚胎形态学评分的重要指标。 Debris is a common phenomenon in in vitro fertilization (IVF) - embryo culture. The generation of debris may be related to apoptosis, gene, age of female, number of oocytes, microinjection of sperm, etc. Although fragmentation is a feature of embryonic development or assisted reproductive technology and in vitro fertilization - in vitro culture However, the production of debris has an impact on the developmental potential of early embryos, implantation rate of transplanted embryos, clinical pregnancy rate and obstetric outcomes. The current number and distribution of debris are still the morphological characteristics of human embryos Important indicators.
