[Experimental study of reconstruction of the vas deferens in the rat]

We performed vasectomy and microsurgical repair of the vas deferens in 20 rats utilizing absorbable and non-absorbable 10-0 sutures. At 40 days the results of the repair procedure were evaluated by seminal fluid and fertility analyses, deferentography, and histologic examination of the anastomoses. The procedure failed in one case that presented occlusion of the spermatic cord from a granuloma.
