This isn’t quite what everyone thinks. No scalpel does not mean “no pain.” No scalpel unfortunately doesn’t mean it is any less anxiety-provoking, nor any less of a procedure. In place of a scalpel is an instrument that stretches the skin to open it up, which still requires local anesthetic. The advantage is most times no stitch in the skin is required and the hole is small. Recovery may be better, but no real difference has been noted.
As a patient, some time should be taken thinking about the options. It is an important milestone so it is important to get it right the first time. If a patient is unsure, vasectomy may not be the right option.
