目的:探讨海岛地区不育男性精液微量元素与精子活力、精子活动率的关系。方法:对48例低活力组精液及50例低活率组精液和40例正常对照组精液分别用伟力彩色精子质量检测系统做精液常规测定(精子活力、精子活动率等)。采用博晖2100铅镉检测仪、MB5五元素仪检测锌、铜、铁、铅、镉等含量。所有数据通过SPSS13.0统计软件包进行统计分析,分别对低活力组精液及低活率组精液和对照组精液中微量元素进行方差分析,并进行相关分析。结果:低活力组及低活率组与正常对照组比较显示铅、镉、锌、镁含量有明显差异,具有统计学意义(P<0.001)。pearson相关分析显示精子活动率与精液总Mg、Pb等微量元素浓度呈线性负相关,相关系数分别为0.742(P<0.001)、0.591(P<0.001);精子活动率与精液中Zn浓度呈线性正相关,相关系数为0.464(P<0.001)。结论:精液中微量元素的含量异常可影响精子的活力及活率,从而导致男子生殖系统功能异常。
Objective: To investigate the relationship between sperm motility and sperm motility of infertile men in island area. Methods: 48 semen of low activity group and 50 semen of low activity group and 40 normal control group were used for sperm routine determination (sperm motility, sperm motility rate, etc) with Weili color sperm quality testing system respectively. Using Bo Hui 2100 lead and cadmium detector, MB5 five elemental instrument detection of zinc, copper, iron, lead, cadmium and other content. All data were analyzed by SPSS13.0 statistical package, and the variance of the trace elements in semen of low activity group, low activity group and control group were analyzed and analyzed respectively. Results: Compared with the normal control group, the levels of lead, cadmium, zinc and magnesium in low activity group and low activity group showed significant difference (P <0.001). Pearson correlation analysis showed that there was a linear negative correlation between sperm motility and total concentrations of total Mg, Pb and other trace elements, the correlation coefficients were 0.742 (P <0.001) and 0.591 (P <0.001) respectively. The sperm motility was linear with the concentration of Zn The correlation coefficient was 0.464 (P <0.001). Conclusion: The abnormal content of trace elements in semen can affect the vitality and viability of sperm, resulting in dysfunction of male reproductive system.
