>some men having ongoing pain in their testicles for the rest of their lives?

I have chronic post vasectomy pain. Many of the guys who end up with Post Vasectomy Pain Syndrome will tell you that if they could have had a taste of the experience before hand, they would never have chosen to get a vasectomy. You are literally risking being in constant pain every day for the rest of your life. It is not uncommon for men with PVPS to want to kill themselves.

How common is chronic pain after vasectomy?

More common than most people think…
