摘要
目的探讨短时授精的时间对常规IVF的受精率及胚胎发育情况的影响。方法将病人授精时间分为4h、6h两组,观察卵母细胞的受精情况及胚胎发育情况。结果两组受精数占获卵数的比率分别为71.1%、75.9%,两组比较差异有显著性意义。受精后正常受精的卵比率为78.4%、79.9%,两组比较差异无显著性意义。卵裂率分别为97.1%、94.5%,两组比较差异有显著性意义。胚胎发育D3优质胚胎率分别为59.9%、54.83%,两组比较差异无显著性意义。结论延长短时授精的时间可以增加受精率,并不能增加正常受精卵的比率,反而使卵裂率降低。
Objective： To study the effect of shortened insemination on the fertilization rate and the development of embryo in conventional IVF.Methods：The patient was divided into two groups,4h,6h,to observe the fertilization of oocyte and the development of embryo.Results：The rate of fertilization in two group is 71.1%,75.9% respectively.Two groups are significant difference.After fertilization,the rate of normal fertilized eggs is 78.4%,79.9% respectively.Two groups are no significant difference.The rate of cleavage is 97.1%,94.5% respectively.Two groups are significant difference.The rate of high quality embryo in day3 is 59.9%,54.83% respectively.Two groups are no significant difference.Conclusions： During prolonging time,it can increase the rate of fertilization,but it can＇t influence normal fertilization rate,and decrease the cleavage rate.
