摘 要:
目的探讨了体外延长培养筛选低评分胚胎中具有发育潜能胚胎的可行性。方法将来自IVF/ICSI的第三天（D3）低评分胚胎进行体外延长培养,观察囊胚形成情况。结果307枚低评分胚胎经体外延长培养后形成53枚囊胚,囊胚率为17.26%,这些囊胚来自85例患者中的33例。结论①体外延长培养能有效筛选出D3低评分胚胎中具有发育潜力的胚胎;②D3胚胎形态评分不能完全预测其发育潜力。[著者文摘]

Abstract:
Objective： To explore feasibility of selecting the with potential for development from day 3 （ D3 ） poor morphological embryos by extending culture to blastocysts. Methods： D3 poor morphological embryos from IVF/ICSI cycles were extended culture, then blastocyst development were observed. Results： Of the 307 poor morphological embryos undergoing extended culture, 53 formed blastocysts （ 17.26% ） either on D5 or D6 of culture, and these blastocysts came from 33 of 85 cycles. Conclusion：① The viable embryos with potential for development were effectively selected by extending culture to blastocyst from d3 poor morphological embryos; ② Embyros developental potential were not entirely predicted by D3 morphology.[著者文摘]
