摘要
目的:研究中国婚检人群中正常年轻男性的精液质量与生活工作方式关系。方法:以问卷形式调查对象一般人口学特征、职业暴露以及工作和生活方式。手淫法采集精液做常规精液分析。对生活工作方式与精液质量指标之间的关系进行非参数比较(wilcoxon秩和检验以及spearman等级相关分析);将精液参数按四分位数划分为4个等级,进行有序多分类的Logistic多因素分析。结果:多因素Logistic分析显示坐姿工作对男性精液质量有不良影响,与非坐姿工作相比,使精子密度降低的可能性较大,可能影响精子存活率及前向运动率。经常清洗外生殖器是精液量降低的保护性因素,经常穿紧身裤可能是精液量下降的危险因素,洗澡的水温较热,睡电热毯等生活方式也会影响精液质量。装修居室增加精子计数降低的危险性,精神紧张对精液质量尚无负面影响。结论:坐姿工作、清洁习惯等生活和工作方式对男性的精液质量可能有很大影响,养成良好的清洁习惯,避免和减少可致阴囊温度升高的生活、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 study relationship between working and other lifestyles and semen quality of normal Chinese young men. Methods: Volunteers' demographic characteristics, occupational hazard contact and working and other lifestyles were investigated by questionnaire. Conventional semen analysis by collecting semen was made. Wilcoxon rank sum analysis, Spearman correlation and ordered response -multiple Logistic a nalysis were used. Results: Multiple Logistic analysis showed that sedentary working resulted in decreasing significantly sperm densities, sperm viability and sperm forward progression percentage. Washing external genitals usually could increase semen volume slightly. Wearing tight pants could reduce semen volume and significantly decrease total sperm counts. Bath with hot water and sleeping on the electrically heated blanket could influence the quality of semen. Room inner fitting -up could decrease the total sperm counts. Emotional stress did not cause much impairment to their semen quality. Conclusions: Male lifestyles such as bath ha bituation, sedentary working have an effect on semen quality, so keeping good bath habituation, changing or giving up the lifestyles that cause higher scrotum temperature are the important way to improve semen quality and to promote male reproductive health.
