Job strain, defined as high job demands and low job control, has not previously been explored as a possible determinant of male fertility. We collected prospective data on job strain among men, and describe the associations with semen quality and probability of conceiving a clinical pregnancy during a menstrual cycle.
Danish couples (N = 399) who were trying to become pregnant for the first time were followed for up to 6 menstrual periods. All men collected semen samples, and a blood sample was drawn from both partners. Job demand and job control were measured by a self-administered questionnaire at entry, and in each cycle the participants recorded changes in job control or job demand during the previous 30 days.
In adjusted analyses, no associations were found between any semen characteristic or sexual hormones and any job strain variable. The odds for pregnancy were not associated with job strain.
Psychologic job strain encountered in normal jobs in Denmark does not seem to affect male reproductive function.
工作压力，定义为高工作要求和低工作控制，此前尚未被探讨为男性生育能力的一个可能决定因素。我们收集了男性工作压力的前瞻性数据，并描述了其与精液质量以及月经周期临床妊娠概率之间的关联。
对首次尝试怀孕的丹麦夫妇（N = 399）进行长达6个月经周期的随访。所有男性均采集精液样本，并从夫妇双方采集血样。在入组时通过自填问卷测量工作要求和工作控制情况，且在每个周期中，参与者记录前30天内工作控制或工作要求的变化。
在调整分析中，未发现任何精液特征或性激素与任何工作压力变量之间存在关联。怀孕几率与工作压力无关。
丹麦正常工作中所遇到的心理工作压力似乎不会影响男性生殖功能。
