Just wondering what happens with a vasectomy - like when your testicals get their tubes cut.Just had an older mate of mine get one(4 kids-so I think they have had enough) and I was just wondering what happens to the blood flow etc to the balls when the tubes get cut. And once they are cut does that mean they - the testicals die, and if they do die why don't guys get infections etc from them once they jave been cut.Just wondering if anyone knows what happens - as I guess in the future I might find myself in a position where I might need a vasectomy as well.
