Yep- it's basically permanent (depending on the type you get). I went to the Doc with my fiancee for this one, it was over fast. He had very mild discomfort and basically acted like I do on my period, ibuprofen and whiskey for 3 days. It is fantastic just to have a great worry & hassle free sex life!! I do like the type they do where they not only snip, but remove about 3/4 inch of vas from each side then cauterize the ends. Pretty much rules out the chance of re-connection.
