高原缺氧环境成年男性精子质量分析

目的：了解长期高原缺氧暴露对成年男性精子功能的影响。方法：以38名驻海拔3 300 m和36名驻海拔5 000 m以上的健康成年男性青年为高原组1和高原组2,以生活在海拔1 300 m的35名同龄成年男性为对照组。行精液常规检测与血常规检查。结果：高原组的精子密度明显低于对照组（P〈0.05）,精子活率在高原组2与对照组有显著差异（P〈0.05）;高原组中血红蛋白浓度与精子数量和活率成正比。结论：虽然人体有一定的代偿功能,但长期驻留高原缺氧环境对成年男性的精子功能有负面影响。

Semen analysis of adult males living in plateau-hypoxia environment

Objective：To investigate the effect of long-term exposure to plateau-hypoxia environment on the sperm function of adult males.Methods：A total of 38 adult males living at the altitude of 3 300 m were recruited as plateau group Ⅰ,36 adult males living at the altitude above 5 000 m were recruited as plateau group Ⅱ,and 35 age-matched men living at the altitude of 1 300 m were used as the control group.Semen analysis and blood routine examination were performed.Results：The sperm density of both plateau groups were significantly lower than that of the control group（P〈0.05）,the ratio of living sperm in plateau group Ⅱ was significantly lower than that of the control group（P〈0.05）.The sperm density and the ratio of living sperm in the plateau groups were proportional with the hemoglobin concentration.Conclusion：Long-term staying at plateau-hypoxia environment has multiple negative effects on the sperm function of adult males despite of the compensation mechanism.
