Many patients report that their chronic prostatitis problems began after they had a vasectomy.
Doctors and scientists have not provided any evidence which firmly disproves or proves that vasectomy can lead to chronic prostatitis. As is usual with issues unresolved by science, we're not going to tell you what to think, but just present the several arguments and let you make up your own mind. This file contains a number of newsgroup comments and private e-mails on the topic. Most of the names and e-mail addresses have been removed. I too have had a vasectomy, but I had my first run-ins with prostatitis before the vasectomy.
