title: [Experimental studies on the reaction of the vas deferens to different traumata].
abstract: In animal experiments the reaction of the ductus deferens to various traumata was studied. The investigations performed on 115 rats were to clarify the following problems: 1. Can a transient trauma, as occurring during preparation or roentgenographic visualization, cause a luminal obstruction? 2. How can vasectomy be done safely in such a manner that chances for a later vasovasotomy are not reduced more than necessary? The findings permit the following conclusions: 1. The surgical exposure of the ductus deferens as well as the checking of its permeability by means of x-ray contrast medium do not lead to a luminal obliteration when performed appropriately under surgical conditions in the course of a vasovasotomy. 2. Sterilization is achieved by partial vasoresection combined with intravasal fulguration. However, the ductus deferens remains understroyed not far from the defect; therefore, after resection of the scarred area a vasovasostomy would still be successful.
