How is vasectomy done without a needle?
Traditionally, a local anesthetic has been injected into the skin and alongside each vas tube with a very fine needle, as small as diabetics use to inject themselves with insulin. One could feel a tiny poke in the skin, then a bit of a squeeze as the anesthetic was applied to each vas tube. However, most people do not like needles of any size … especially there! A MadaJet is a spray applicator which delivers a fine stream of liquid anesthetic at a pressure great enough to penetrate the skin to a depth of about 3/16″, deep enough to envelop the vas tube held snugly beneath the skin. Each vas is positioned in turn beneath the very middle of the front scrotal wall and given two or three squirts. That numbs the skin and both vas tubes adequately for 99% of men. The other 1% (usually men who have thick skin or scarring due to prior surgical procedures in the area) will require a bit more anesthetic delivered with a fine needle, usually with no pain at all because of the partial anesthesia
