Power-frequency magnetic field exposure science as it relates to men and couples have not been explored despite the advantage of this information in the design and interpretation of reproductive health epidemiology studies. This analysis examined the distribution and temporal variability of exposures in men, and the correlation of exposures within couples using data from a longitudinal study of 25 men and their female partners recruited from an infertility clinic. The average and 90th percentile demonstrated fair to good reproducibility, whereas the maximum showed poor reproducibility over repeated sampling days, each separated by a median of 4.6 weeks. Average magnetic field exposures were also strongly correlated within couples, suggesting that one partner's data could be used as a surrogate in the absence of data from the other for this metric. Environment was also an important effect modifier in these explored matters. These issues should be considered in future relevant epidemiology studies.
尽管工频磁场暴露科学对于男性及配偶的信息在生殖健康流行病学研究的设计和解释方面具有优势，但尚未得到探索。本分析利用从一家不孕不育诊所招募的25名男性及其女性伴侣的纵向研究数据，研究了男性暴露的分布和时间变异性，以及伴侣间暴露的相关性。在重复采样日（每次采样日间隔中位数为4.6周）期间，平均暴露量和第90百分位数显示出较好到良好的可重复性，而最大值的可重复性较差。伴侣间的平均磁场暴露也具有很强的相关性，这表明在缺乏另一方数据的情况下，一方伴侣的数据可作为该指标的替代数据。在这些研究问题中，环境也是一个重要的效应修饰因素。未来相关的流行病学研究应考虑这些问题。
