Description
Summary:To assess the association between varicocele and hypogonadism, or erectile dysfunction. We searched MEDLINE, EMBASE, LILACS, CENTRAL, and other sources. We included cohort, case-control, and cross-sectional studies. The primary outcome was the association between varicocele and hypogonadism, or erectile dysfunction, and the secondary outcome included semen analysis. We assessed the risk of bias with the Newcastle-Ottawa Scale. We performed statistical analysis in Review Manager 5.3 and reported information about the Odds Ratio (OR) with a 95% confidence interval. We produced a forest plot for the primary outcome. We included ten studies in qualitative analysis and six studies in quantitative analysis. Most of the cross-sectional studies showed a low risk of bias, not so for the two case-control studies, which represented a high risk of bias. Most of the reports described a correlation between having varicocele and presenting low testosterone levels: the meta-analysis showed that there is a significant association between varicocele and hypogonadism (OR 3.27 95% CI 1.23 to 8.68). Regarding varicocele and erectile, only one study showed a significant difference in erectile function in comparison to varicocele patients and men without varicocele. There is an association between varicocele presence and hypogonadism, although more studies are needed. Besides, not much is reported about an association between varicocele and erectile dysfunction, but impairment can occur through hormone disturbances.
