Men had a median (IQR) age of 35.5 (32.0, 39.3) years and BMI of 26.3 (24.4, 29.9) kg/m2. Among the 656 men, 53% (n = 345) reported primarily wearing boxers (loose underwear) (Table I). This group of men were, on average, younger, slimmer and more likely to take hot baths/Jacuzzi compared to men who did not report wearing most frequently boxers (Table I). The distribution [median (IQRs)] of sperm concentration and total count among the 1186 semen samples was 62.2 (28.2, 113) mil/mL and 156 (71.4, 298) mil/ejaculate, respectively (Supplementary Table SI). Median (IQR) serum FSH, LH and testosterone concentrations of 7.29 (5.53, 10.2) IU/L, 9.67 (7.21, 13.2) IU/L and 400 (326, 482) ng/dL, respectively, were measured among men for whom reproductive hormone level data was available.
