We evaluated sperm parameters and functional tests, as well as the expression of CBS, CSE, and HO-1 proteins using Western blot analysis. Serum levels of methionine, homocysteine, and taurine were analyzed through high-performance liquid chromatography, while vitamin B6 concentrations were measured using enzyme-linked immunosorbent assay. For group comparisons, we employed ANOVA and the Tukey test, considering a P<0.05 as significant.</p><p><strong>Results: </strong>We observed a significant reduction in both sperm quality and functional parameters. Additionally, there was a notable decrease in the expression of CBS, CSE, and HO-1 proteins, as well as circulating vitamin B6 levels, in the varicocele group compared to the control and sham groups (P<0.001).</p><p><strong>Conclusion: </strong>The results of this study suggest that one possible cause of increased oxidative stress in varicocele may be the reduced expression of testicular enzymes involved in the production of endogenous antioxidants, which are associated with the transsulfuration pathway. However, further studies are needed to confirm these findings.</p>","PeriodicalId":14080,"journal":{"name":"International Journal of Fertility & Sterility","volume":"19 1","pages":"80-87"},"PeriodicalIF":2.3,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11744200/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143004981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
