title: [Experimental vasectomy: comparison of the testicular structure with various surgical techniques].
abstract: We have performed experimental vasectomies in dog in order to study different repercussions of various surgical techniques on the testicular structure. The closed technique, with ligature of both cut ends of the sectioned vas deferens caused a severe tubular atrophy, which finally destroyed the architecture of the testis with compensating hypertrophy of the intertubular connective tissue. The technique of the "open cut end", leaving the proximal end free and allowing the normal drainage of the vas deferens into the interstitial space of the spermatic cord, had not any influence on the testicular-structure, at least in the studied period of time, now one year. We can't reject any long-term immunological phenomena. The conclusion of this study is that the peculiarities of the surgical techniques of vasectomy have a decisive influence on the preservation of the testicular structure.
