Min and Min linked exposure to loud-ish noises and male infertility. The researchers report that they “examined an association between daytime and nocturnal noise exposures over four years . . .. and subsequent male infertility. We used the National Health Insurance Service-National Sample Cohort (2002–2013), a population-wide health insurance claims dataset. A total of 206,492 males of reproductive age (20–59 years) with no history of congenital malformations were followed up for an 8-year period. . . . Data on noise exposure was obtained from the National Noise Information System. . . . Based on WHO criteria, adjusted odds for infertility were significantly increased . . . in males exposed to night time noise ≥ 55 dB. We found a significant association between exposure to environmental noise for four years and the subsequent incidence of male infertility, suggesting long-term exposure to noise has a role in pathogenesis of male infertility.” Statistical tools were used to eliminate factors such as age, income, and BMI as possible explanations for the effects found.
