The inverse variance weighting method was the main method used to estimate the association, and sensitivity analyses were also performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A greater risk of erectile dysfunction was significantly associated with a higher genetic susceptibility to leisure computer usage (odds ratio\u00a0=\u00a03.57; 95% confidence interval =\u00a01.78\u20137.16; <jats:italic>p\u00a0<\/jats:italic>&lt;\u00a00.001). No evidence was obtained to suggest that watching television or driving for leisure increased the risk of erectile dysfunction. No association was found between computer use and depression, anxiety, C reactive protein, E\u2010selectin, matrix metalloproteinase 7, or other sex hormones, with the exception of follicle\u2010stimulating hormone levels (odds ratio\u00a0=\u00a00.29; 95% confidence interval\u00a0=\u00a00.12\u20130.69; <jats:italic>p\u00a0<\/jats:italic>=\u00a00.01).
