Like a number of folks have already said: no big deal. Do what the doc reccommends and it goes just fine. Afterwords, you get to be the "sport model"--all play, no pay

.
The actual procedure is a bit disconcerting for lots of people, though. Shave the area the morning of the procedure (much better to do it oneself--or have your S.O. do it!). Feet up in stirrups (you'll then understand why women complain about that) Tape the working tackle outta the way, snip, pull a small section of vas through the tiny incision, snip again and tie-off (some--all?--urologists also use cautery), repeat for other ball. A couple of small stitches and you're good to go. Then ice and take it easy.
In my experience with various friends, it was the lead-up that was more problem than the actual vasectomy. Some guys are such big babies about that sort of thing.
