目的探讨年龄对精液质量的影响。方法对乌鲁木齐市526例男性不育症患者的精液进行回顾性分析。检查分析记录:精液量、密度、活动率、a级精子总数(%)、a+b级(%)、精子总数,结果依据年龄分3组,即21-30岁(组1)、31-40岁(组2)、41-50岁(组3)。结果精液量方面:3组均值逐渐升高,而3组之间比较差异无统计学意义;密度方面:3组均值逐渐降低,而3组之间比较差异无统计学意义;精子总数、(a+b)%、活动率方面:组2均值高于组1、3,而3组之间比较差异无统计学意义;a%方面:组2均值高于组1、3,而组2与组3之间比较差异有统计学意义。结论男性不育症患者的精液随年龄的增长对前项运动精子有一定的影响。

Results In terms of semen volume, mean of three groups increased gradually, but there was no significant difference among the three groups. In terms of density, mean of three groups decreased gradually, but there was no significant difference among the three groups + b)%, activity rate: group 2 mean was higher than group 1, 3, but no significant difference between the three groups; a%: group 2 mean was higher than group 1,3, and group 2 and group 3 between the difference was statistically significant.
