The objective of the study was to assess whether reduced semen quality in infertile couples is associated with occupational exposures known to be hazardous to fertility. Results of the first semen analysis were linked to occupational exposure data from a self-administered questionnaire. Reduced semen quality was found in men exposed to electromagnetic fields (odds ratio, 3.22; confidence interval, 1.46 to 7.09). A tendency toward reduced semen quality was seen in commuters (OR, 1.52; CI, 0.89 to 2.59), shift workers (OR, 1.46; CI, 0.89 to 2.40), and men exposed to heavy metals (OR, 1.47; CI, 0.76 to 2.87). In general, the impact of occupational exposure on semen quality in infertile couples in Norway seemed to be minor. However, occupational exposure mapping is still important in individual infertility investigations.
该研究的目的是评估不育夫妇精液质量下降是否与已知对生育有害的职业暴露有关。首次精液分析的结果与来自一份自填式问卷的职业暴露数据相关联。在暴露于电磁场的男性中发现精液质量下降（优势比为3.22；置信区间为1.46至7.09）。通勤者（优势比为1.52；置信区间为0.89至2.59）、轮班工人（优势比为1.46；置信区间为0.89至2.40）以及暴露于重金属的男性（优势比为1.47；置信区间为0.76至2.87）中出现了精液质量下降的趋势。总体而言，职业暴露对挪威不育夫妇精液质量的影响似乎较小。然而，在个体不育调查中，职业暴露图谱绘制仍然很重要。
