[Vasectomy and its reversibility]

The authors report their experience of 2000 vasectomies. They discuss the indications, the technical aspects, the complications, the immunological consequences and the pathological results on the vas deferens, the epididymis and the testis. They report thereafter their experience of vaso-vasostomies (320 cases). They discuss their results on a mechanical (repermeabilization) and functional (% of pregnancies) point of view.
