体外受精(IVF)中移植胚胎选择根据D2、D3卵裂球外观、碎片和其他可见特征进行胚胎形态学分级,但只有不到30%的移植胚胎能达到完全发育潜能,因此需要选择更好的标准,特别是可获得3个以上I级胚胎时。已有报道原核期合子形态评分与植入率强相关,可预测植入和妊娠,受到更多关注。研 Embryonic Embryo Selection in IVF Embryo morphological grading based on D2, D3 blastomere appearance, fragmentation, and other visible features, but less than 30% of transplanted embryos reach full developmental potential and therefore need to be better selected Standard, especially when more than three Class I embryos are available. It has been reported that prokaryotic zygotic morphological scores are strongly correlated with implantation rates, predictable implantation and pregnancy, receiving more attention. research
