Bilateral varicocele: impact of right spermatic vein ligation on fertility

Abstract

The most frequent cause of male infertility is left varicocele. The surgical or laparoscopic approach for spermatic vein ligation is considered the best method of treatment. The approach to a clinically significant left varicocele associated with a right varicocele (frequently of a smaller size) is not univocal. We analyzed the seminal responses obtained in 65 patients with bilateral varicocele (grades 2 to 3 on the left side and grade 1 on the right side) assigned randomly to undergo unilateral or bilateral ligation. There were no significant differences between the 2 groups with regard to seminal recovery.
