Have you heard of the “no needle-no scalpel vasectomy?” The technology for the painless part is old but its application to providing needle free anesthesia for a vasectomy is relatively new. If you are of “vasectomy age” you should inquire about it before you choose a vasectomy, particularly if you are needle phobic.
While I was researching the relationship of prostate cancer and vasectomy, I came across a study that determined that there was no conclusive link between the two. One of the main researchers was our old friend and ” anti-PSA and screening” Otis Brawley. I found that interesting. The guy gets around.
