Background: Given the variability in abdominal physiology and hernia presentation between sexes, better comprehension of sex-related differences in outcomes would tailor surgical approach and counseling regarding postoperative outcomes. This meta-analysis aims to appraise the effect of sex on the outcomes of ventral hernia repair. Methods: A literature search in PubMed, EMBASE and Cochrane selected studies comparing outcomes of ventral hernia repair between sexes. Postoperative outcomes were assessed by pooled and meta-analysis. Statistical analysis was performed using RevMan 5.4. Results: We screened 3128 studies, reviewed 133, and included 18 observational studies, which encompassed 220,799 patients following ventral hernia repair. Postoperative chronic pain was significantly higher in female (OR 1,9; 95% CI 1,64–2,2; p ​< ​0,001). There were no significant differences in complications, readmission, or recurrence rates between females and males. Conclusion: Female sex is associated with a higher risk of postoperative chronic pain following ventral hernia repair.
