Effects Of Conventional And Open-Ended Vasectomies On The Testicular And Epididymal Structures In Rabbits

Background and Objective:Vasectomy is an effective and one of the most widely used methods of male contraception; the conventional and open-ended vasectomies are two major surgical techniques. It is still unclear what effects vasectomy has on the spermatogenesis in the testis and on the epididymal structures. It has potential influence on the fertility after reversal of the operation and on the success rate of artificial fertilization. We previously observed that vasectomy induced damage to spermatogenesis in rabbits. The damage was most severe at day 10 after operation, occurring in all the vasectomized testes, but the damage was less severe 6 or 12 months after operation, occuring in half of the vasectomized testes. But it was unclear whether the damage was related to operational trauma or occlusion of the vas deferens. Comparing the effects of bilateral conventional and open-ended vasectomies on the testicular and epididymal structures in rabbits, this study was therefore further undertaken to determine whether the operational trauma had an impact on the post-operational complications...
