INCISION METHODS
Usually, a local anesthetic is injected into the pelvic area. Then, the doctor makes an incision on each side of the scrotum to reach each vas deferens — the tubes that carry sperm. Sometimes a single incision is made in the center. Each tube is blocked. In most procedures, a small section of each tube is removed. Tubes may be tied off or blocked with surgical clips. Or, they may be closed using an instrument with an electrical current.
