Analysis of the factors affecting abnormal fertilization on in vitro fertilization 体外受精后异常受精的影响因素分析
The normal fertilization rate, abnormal fertilization rate, the cleavage rate and good embryos rate were analyzed in two groups. 比较有无纺锤体组卵子的正常受精率、异常受精率、卵裂率以及良好胚胎形成率。
In vitro fertilization, manipulation and culture environment might affect the DNA methylation pattern and result in abnormal methylation pattern of in vitro fertilization embryos. 本实验结果部分显示了体外受精、操作及培养环境可能对正常的DNA甲基化模式产生了影响,造成了体外受精植入前胚胎甲基化模式异常。
