    Abstract:
    Vasectomy is the only method of male sterilization that is simple, reversible, and does not change sex habits. Careful patient selection and education is as important to the successful outcome of the procedure as a competent surgical technique. A successful surgical procedure requires good rapport with the patient, complete anesthesia, anatomical knowledge of the vas, excision of only a small length of the vas, sealing of the cut ends by electrocoagulation, and separation of the cut ends by suturing. Methods of non-operative vasectomy produce sterility through the use of injections of ethyl alcohol and formalin into the vas or through injection of an electrical needle. Congestive epididymitis and sperm granulomas are complications resulting from vasectomy. The most severe complication however, is the psychological depression that can follow the procedure. Vasovasostomy can be done and is often successful. The procedure requires the use of microsurgical techniques to join lumens of different diameters so that a watertight anastomosis is achieved. The reasons for vasovasostomy failure are difficult to determine, but often can be attributed to the formation of obstructions. Animal studies on vasovasostomy failure are difficult to conduct because of the lack of a suitable animal for study. Other methods of reversible vasectomy include the use of rigid and soft valves. Rigid, metal valves do not appear to be as potentially successful as soft valves.
