After vasectomy, those who wish to regain their fertility can restore the patency of the vas deferens through a vasectomy microanastomosis. The procedure is performed under general anesthesia, and the use of an operating microscope can greatly improve the precision and success rate of the procedure. If the abstinence has been prolonged and may cause obstruction of the near testicular segment of the vas deferens, a microscopic anastomosis of the vas deferens epididymal duct will be performed.
