摘要(Abstract)：

目的:了解我省男性精液质量并对其进行综合评价,探讨影响精液质量的环境行为因素。方法:对贵阳市和遵义市201例正常男性志愿者进行流行病学调查和两次精液检查。应用SAS软件对资料统计分析和单因素成组比较。结果:精液量为(2.49±1.24)m l,精子前向运动百分率为(43.82±3.89)%;精子密度为(52.87±33.36)×106/m l,精子存活率为(78.40±8.13)%;精子正常形态率为(37.70±8.1)%。精液质量各项常规指标都符合WHO标准的对象仅占12.4%。经常清洗外生殖器有助于提高精子密度,清洗外生殖器时清洗包皮者其精子密度和精子总数与清洗时不翻包皮者比较有显著性差异(P<0.05)。长时间坐姿工作使精子前向运动百分率、密度、总精子数都有所下降,对精子存活率有极显著不良影响(P<0.01)。结论:研究结果初步揭示我省正常男性精液质量各项指标与WHO标准相比较偏低。清洁卫生习惯、穿着裤子方式和坐姿工作对男性的精液质量可能有很大影响。养成良好的个人卫生清洁习惯、避免和减少可致阴囊温度升高的生活及工作方式是提高精液质量、促进男性生殖健康的重要途径。
Objective: To explore the status of semen quality in Guizhou province,and to study the influences of working and other lifestyles on semen quality.Methods: Questionnaire survey and twice conventional semen analysis were carried out to 201 volunteers.Statistics of routine semen parameters(mean and median value, range,percentiles,etc) and logistic regressions were done using SAS software. Results: The mean and standard deviation of semen volume was(2.49±1.24)ml,sperm forward progression percentage(43.82±3.89)%,sperm density(52.87±33.36)×106/ml,sperm viability(78.40±8.13)%,and morphological percentage of normal sperm(37.70±8.1)%.There was only 12.4% of the subjects whose semen indices met all WHO standards.Washing external genitals usually could increase semen density.The differences of semen density and total sperm counts between subjects that washing external genitals with prepuce turning over and those without prepuce turning over were obvious(P<0.05).Sedentary working could reduce sperm forward progression percentage,sperm density and total sperm count.It showed an significant effect on sperm viability(P<0.01).Conclusions: The semen quality of hcalthy men in Guizhou province is lower than WHO standards.The lifestyles such as bath habit,wearing tight pants,sedentary working have obvious effects on semen quality.So,It's important way of improving semen quality and promoting male reproductive health to keep good bath habituation,give up lifestyles that might cause higher scrotum temperature.
