The methods used encompassed inverse variance weighting, MR-Egger, weighted median, simple mode, and weighted mode residual sum and outlier techniques. The MR-Egger intercept test was utilized to assess pleiotropy, while Cochran's Q statistic was employed to measure heterogeneity.</p><p><strong>Outcomes: </strong>We employed inverse variance weighting MR as the primary statistical method to assess the causal relationship between exposure factors and ED.</p><p><strong>Results: </strong>Genetically predicted PCa demonstrated a causal association with an elevated risk of ED (odds ratio, 1.125; 95% confidence interval, 1.066-1.186; <i>P <</i> .0001). However, no compelling evidence was found to support associations between genetically determined benign prostatic hyperplasia, CKD, immunoglobulin A nephropathy, membranous nephropathy, nephrotic syndrome, kidney ureter calculi, and the renal function parameters investigated, and the risk of ED.</p><p><strong>Clinical implications: </strong>The risk of ED is considerably amplified in patients diagnosed with PCa, thereby highlighting the importance of addressing ED as a significant concern for clinicians treating individuals with PCa.</p><p><strong>Strengths and limitations: </strong>This study's strength lies in validating the PCa-ED association using genetic analysis, while its limitation is the heterogeneity in study results.</p><p><strong>Conclusion: </strong>The results of this study suggest a potential link between PCa and a higher risk of ED.</p>","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"12 1","pages":"qfae002"},"PeriodicalIF":2.6,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10859556/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139723965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
