No-scalpel vasectomy is the safest surgical method available today for male sterilization. There is less risk of infection because the opening is so tiny. There may be less discomfort during the surgical procedure because local anesthetic is administered to numb the vas area instead of just the incision site. There is less discomfort after the operation than with more traditional methods. The procedure is faster, usually less than ten minutes.
Recovery time is typically shorter.
There are no stitches to be removed and the healed site is usually invisible. Yes, but only once in every 250 cases. A vasectomy can fail if the tubes were not completely sealed off during the surgery. Or if the cut ends of the vas deferens tubes join together by themselves. Or if an opening develops that allows sperm to pass through.
