The high failure rate of vasovasotomy to restore fertility in vasectomized men prompted this investigation using guinea pigs as the experimental animals. The vasa were divided and absorbable intravasal stents were inserted into the lumens of the vasa at the site of anastomosis. The success or failure to secure patency and reestablish fertility was appraised by histologic sections, vasograms, semen analyses, and breeding tests. A second group of animals had silicone plugs equipped with a detachable central pin placed in both vasa. The design of this procedure was to produce an occlusive azoospermia which might be reversed by removing the central pin. Similar tests were used to establish the effectiveness of this reversible device in producing a temporary sterilization. The procedures were controlled by sham operations and insertion of plugs without pins. |
