目的探讨计算机职业对男性精液质量的影响。方法对146例计算机职业男性,应用北京伟力公司WLJY-9000型彩色精子质量分析系统,从精液量、液化时间、精子总数、精子密度、a级精子百分率、b级精子百分率、a+b级精子百分率、精子活率等方面进行分析。结果本研究发现:虽然,每周使用计算机时间>30h,且工作年限>3年的计算机职业男性的精液量、液化时间、精子总数和精子密度与正常对照组之间差异无显著性(P>0.05),但是,a级精子百分率、b级精子百分率、a+b级精子百分率、精子活率显著降低(P<0.05)。结论每周使用计算机时间>30h,且工作年限>3年的计算机职业男性,可引起精液质量异常。
Objective To explore the influence of computer occupation on male sperm quality. Methods A total of 146 computer male workers were enrolled in this study. The WLJY-9000 color sperm mass analysis system of Beijing Weili Company was used. The results showed that there was no significant difference in sperm volume, liquefaction time, total number of sperm, sperm density, grade a sperm percentage, grade b sperm percentage, Percentage, sperm motility and other aspects of analysis. Results The present study found that although there was no significant difference in semen volume, liquefaction time, total number of sperm and sperm density among computer-occupational men who used computer for more than 30 hours per week and their working years were more than 3 years (P> 0.05). However, a-grade sperm percentage, b-grade sperm percentage, a + b grade sperm percentage and sperm motility decreased significantly (P <0.05). Conclusion Computer professional men who use computer for more than 30 hours per week and work for more than 3 years can cause abnormal semen quality.
