The tubes are then tied off, cauterized, or blocked. The tiny puncture heals quickly. No stitches are needed, and no scarring takes place. The no-scalpel method reduces bleeding and decreases the possibility of infection, bruising, and other complications. You and your doctor will discuss which type of anesthetic to use.
Local anesthetic is most usual.
Sometimes a general anesthetic is called for. No pain is felt under general anesthesia because you are asleep. Some discomfort may be felt when the local anesthetic is injected or when the tubes are brought into the incision. As with any surgery, there's some discomfort after the operation. It will be different for each man.
