目的探讨不育男性精子密度,活动率,前向活动率(a+b)的正常形态和存活率之间的相互关系。方法采用WHO推荐的标准化方法,对775例不育男性精液进行常规、形态学和精子活体染色技术检测分析。结果精子存活率与密度、活动率、前向活动率、正常形态各指标间均有正向相关性,相关系数(r)分别为0.175、0.803、0.749、0.274。结论精子存活率与精液常规检查参数和精子正常形态之间具有较好的相关性,精子存活率可作为评价精子活动率的补充指标,并且是一个很好的评估。
Objective To explore the relationship between the normal morphology and survival rate of infertile men with sperm density, activity rate and forward activity rate (a + b). Methods According to the standardization method recommended by the WHO, 775 infertile men were tested by routine, morphological and viable sperm staining techniques. Results There was a positive correlation between sperm survival rate and density, activity rate, forward activity rate and normal morphology. The correlation coefficients (r) were 0.175,0.803,0.749,0.274 respectively. Conclusion There is a good correlation between sperm survival rate and routine sperm parameters and sperm normal morphology. Sperm survival rate can be used as a supplementary index to evaluate sperm motility rate, and is a good assessment.
