The increasing popularity of cycling has sparked debates about its potential association with male erectile dysfunction (ED). This study aimed to systematically evaluate the relationship between cycling and ED through a meta-analysis to provide evidence-based conclusions. A comprehensive literature search was conducted across databases (PubMed, Web of Science, CNKI, etc.) up to December 20, 2024, to identify observational studies investigating cycling and ED prevalence. Eligible studies were screened, and data were extracted for quality assessment using the AHRQ (Agency for Healthcare Research and Quality) bias risk tool. Meta-analysis, sensitivity analysis, and publication bias assessment were performed using Review Manager 5.3 and Stata 18.0. Among 271 screened studies, 31 met the inclusion criteria, with 8 studies (4,729 cyclists vs. 2,843 non-cyclists) eligible for meta-analysis. Pooled results revealed no significant difference in ED prevalence between cyclists and non-cyclists risk ratio (RR) = 1.16, 95% confidence interval (CI): 0.79–1.71, P = 0.44. Subgroup analyses stratified by age, geographic region, and assessment tools showed consistent non-significant associations (P > 0.05). Sensitivity analyses confirmed robust outcomes, and Egger’s test indicated publication bias (P = 0.23). Current evidence does not support a causal relationship between cycling and erectile dysfunction in males.
