Effect of Scrotal Veins Ligation on Results of Varicocelectomy Regarding Semen Parameters and Testicular Volume

Background: There was disagreement in some studies about the benefit of varicocele treatment on testicular size.Objective: The aim of this study was to evaluate scrotal veins contribution to varicocele and the effect of its ligation on semen parameters and testicular volume.Patients and Methods: Sixty patients with clinically and sonographically detectable varicocele grades II and III, and abnormal semen were randomly divided into 2 equal groups: Group I were treated by subinguinal varicocelectomy only, and Group II were treated by subinguinal varicocelectomy with additional scrotal veins ligation. They were subjected to semen analysis and scrotal color Duplex to measure testicular size.Results: Both surgical techniques showed significant improvement in semen parameters (count and motility) and testicular volume measured by Duplex. However, the postoperative improvement in sperm count and testicular volume was significantly higher in Group II. Postoperative pregnancy rates were comparable with no significant difference between both groups.Conclusion: The postoperative improvement in sperm count and testicular volume was significantly higher in patients treated by subinguinal varicocelectomy with additional scrotal veins ligation.
