目的探讨不同授精方式对胚胎的体外发育潜能的影响。方法将新鲜行囊胚培养的周期分为IVF组和ICSI组,统计了两组的卵裂率,可用胚胎率及囊胚培养结局。结果 IVF组的第三天可用胚胎率显著低于ICSI组,但后续囊胚形成率和可用囊胚形成率均显著高于ICSI组。结论 ICSI相关因素降低了第三天以后胚胎的发育潜能。
Objective To investigate the effects of different insemination methods on embryonic in vitro development potential. Methods The cycle of fresh blastocysts was divided into IVF group and ICSI group. The cleavage rate, available embryo rate and blastocyst culture outcome were calculated. Results The available embryo rate on the third day in IVF group was significantly lower than that in ICSI group, but the blastocyst formation rate and blastocyst formation rate were significantly higher in IVF group than in ICSI group. Conclusion ICSI-related factors reduce the developmental potential of embryos after the third day.
