Male patients with gout or hyperuricemia have a wide range of reproductive health challenges.

Two reviewers extracted the data and completed quality assessment using the Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality checklist. Meta-analysis was conducted using Review Manager 5.4 and Stata 18.0. The protocol was registered on PROSPERO (CRD 420261302205). The outcomes such as sexual function, reproductive hormones, and fertility were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the literature search, 1,527 articles were retrieved. Among these, 11 studies met the inclusion criteria. This meta-analysis included 104,277 patients with gout or hyperuricemia and 342,621 control subjects. The meta-analysis results showed that the risk of erectile dysfunction was higher in patients with gout (RR\u00a0=\u00a01.37; 95% CI\u00a0=\u00a01.14 to 1.65,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0&amp;lt;\u00a00.001). Compared with the control group, patients with gout or hyperuricemia showed lower levels of testosterone and estradiol (testosterone: MD = \u22121.00, 95% CI = \u22121.39 to \u22120.62,\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt;\u00a00.001; estradiol: MD = \u22124.67, 95% CI = \u22129.31 to \u22120.02,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a00.05).
