五年来我院门诊不育男性精液质量变化情况的研究

目的：分析我院近五年来门诊不育男性精液参数的变化趋势。方法：收集了五年来总计51258名不育男性的精液资料，控制禁欲时间等参数后对精液情况的变化进行统计分析。结果：患者年龄没有明显变化，50％以上是在25—35岁之间。无精症患者比例由6％增加到10％，少精症患者的比例由60％增加到85％，弱精症患者的比例由78％增加到92％，少弱精症患者由40％增加到56％，其中弱精症患者所占的比率最大。随着年龄的增加，精子密度呈现下降趋势，由17×10^6／mL降到9×10^6／mL。精子活率由2004年的47．27％降到2008年的32．97％，精子活力由2004的33．60％降到2008年的28．30％。结论：过去五年来我院门诊男性不育患者的年龄主要集中在30岁左右，弱精症患者所占的比例最大，无精症、少精症、弱精症、少弱精症患者的比例都有所增加，精子密度、精子活力和精子活率都表现出下降趋势。

Asthenozoospermia group have the largest percentage. Sperm concentration decrease from 17×10^6/mL to 9×10^6/mL as age increase. Sperm motility, and vitality decrease from 47.27% to 32. 97%, and from33.60% to 28. 30% respectively for the year from 2004 to 2008. Conclusion： The age of male infertility outpatients in our hospital focused on 30 year old. Azoospermia , oligospermia , asthenozoospermia and oligoasthenozoospermia groups all have increased.
