45例弱精子症患者精子存活率与总活力的相关性分析

The correlation of sperm survival rate to the general motility of patients with asthenospermia

目的分析弱精子症患者精子存活率与总活力的关系。方法按照精子总活力,将45例行精液分析的患者进行分组,其中精子总活力0~10%的10例重度弱精子症患者为A组,总活力11~20%的15例中度弱精子症患者为B组,总活力21~40%的20例轻度弱精子症患者为C组,比较各组精子的常规参数及存活率。结果三组间的精子存活率、精子活力、精液参数中精子密度、正常形态精子的均值比较差异有统计学意义（P〈0.01）;A、B、C组的精子存活率明显高于总活力（P〈0.01）。精子存活率与精子总活力、密度及正常形态精子比例呈正相关（均P〈0.01）。结论弱精子症患者精子存活率与总活力密切相关,精子存活率可作为评价精子活力的一个很好的补充指标。

Objective To understand the survival rate of sperm to the general motility. Method according to motility,45 patients for routine semen analysis were first divided into three groups according to the motility of their sperm. Group A consists of those（ n = 10） with motility rate of 0 ~ 10%. Group B consists of those（ n = 15） with the total activity rate of11 ~ 20%. Group C consists of those（ n = 20） with total activity rate of 21 ~ 40%. The common parameters of sperm and the survival rate of the three groups were then documented and compared. Findings The difference among the three groups in sperm survival rate,sperm motility,semen parameters of sperm density and normal morphology sperm mean was statistically significant（ P〈0. 01）. In all three groups the sperm survival rate was significantly higher than that of total activity（ P〈0. 01）. Sperm survival rate was found to be positively correlated with sperm density,total activity and the percentage of normal sperm morphology（ P〈0. 01）. Conclusion Human sperm survival rate is closely correlated with the total activity of sperm. S perm survival rate can serve as an major indicator in evaluating sperm motility.
