精液质量与季节关系探讨

Discussion of the correlation between seasons and semen quality

目的探讨季节变化与精液量、pH值、精子密度、活率及活力的关系。方法用计算机辅助精子分析（CASA）技术,按照《WHO人类精液及精子-宫颈粘液相互作用实验室检验手册》,使用北京伟力公司WLJY9000仪器,对1386例育龄男性完整精液标本进行分析,并分为春季（3-5月）、夏季（6-8月）、秋季（9-11月）、冬季（12-2月）4组,分析比较各组精液参数。结果 1386名育龄男性精液量（2.78±0.89）ml,pH值（7.46±0.15）,精子密度（73.59±50.62）×10^6/ml,精子活率（65.71±19.39）%,a级精子（29.89±13.26）%,a＋b级精子（48.47±15.64）%。其中正常组924例（66.67%）,异常组462例（33.33%）。各组精液量、pH值、精子密度、活率及活力差异没有统计学意义。结论季节变化对精液参数没有显著影响。

Objective To explore the effects of seasons on the semen quality by analysis semen volume,pH value,sperm concentration,viability and motility.Methods According to 《WHO laboratory manual for the examination of human semen and sperm-cervical mucus interaction》,whole the 1386 semen samples of the fertile men who hospitalized in our hospital were analyzed through CASA（WLJY9000,made by BEIJING WEILI Company）.All the samples were divided into four groups：spring group（Mar.-May）,summer group（Jun.-Aug.）,autumn group（Sept.-Nov.）and winter group（Dec.-Feb.）.Results Among the 1386 fertile men,the semen volume was（2.78±0.89）ml,the pH value was（7.46±0.15）,the sperm concentration was（73.59±50.62）×10^6/ml,the sperm viability rate was（65.71±19.39）%,grade A sperm was（29.89＋13.26）%and the grade A and B sperm was（48.47±15.64）%.The samples with normal sperm quality accounted for 66.67%（924/1386）in contrast with abnormal 33.33%（462/1386）.Compared among the different groups,there was no significant difference in the semen parameters.Conclusion Different seasons would not affect semen quality.
