original Article Background: Sub-inguinal varicocelectomy is widely used among surgeons. Objectives: The aim of this study was to evaluate the outcome of varicocelectomy using a modified microsurgical method, specifically a loupe-assisted method, and its effects on sperm parameters in infertile men. Patients and Methods: This study was performed in 40 patients who presented with varicocele. All patients had at least a 1-year history of infertility with abnormal semen pa-rameters and varicocele proven by physical examination and confirmed with color Dop-pler ultrasound. Routine preoperative investigations were performed. Semen analysis and hormonal profiling were also performed and repeated postoperatively for follow-up. half of the patients (20 patients) were treated by a sub-inguinal approach assisted by loupe magnification (Group A) and the other half was treated by the same approach but without magnification (Group B). To facilitate the procedure, an ×3.0 loupe was used during the spermatic cord dissection at the level of the external inguinal ring. During dissection, the dilated veins, including the vassal veins and external spermatic veins
