TIGHT UNDERPANTS AND TROUSERS AND RISK OF DYSPERMIA

The association between the wearing of tight underpants and trousers a nd risk of dyspermia has been analysed using data from a case-control study. Cases included infertile men with a diagnosis of unexplained dy spermia. Normospermic men of infertile couples were eligible as contro ls. In comparison with men usually wearing loose underpants, the odds ratio (OR) of dyspermia was 1.9 (95% confidence interval, CI, 0.9-4.1) in those wearing tight underwear. Likewise, the OR of dyspermia was 1 .6 (95% CI 0.9-3.0) in men reporting usually wearing tight trousers (i ncluding jeans), in comparison with those wearing loose trousers.
