You must be young. Vasectomies are a perfectly normal and routine operation in later life. I'd wager a large percentage (if not a majority) of age 50+ men in the US have them done. It hurts for a weekend, and then it's over, not a big deal. This sounds like a significant improvement over the current procedure.

In my sample group, it's not as large as you think. I'm a 43 year-old post-vasectomy father and out of a group of ten close male friends/relatives I've encountered 2 close calls and 2 oops babies. And these are intelligent responsible men. The majority of the excuses range from "I just never got around to it" to "I don't want to get cut". Seriously?
I'm in my mid-twenties, and was seriously considering it when I thought it was reliably reversible. My reading at the time indicated that this wasn't the case and there was a good chance that you'd stay sterile after reversing the operation. This struck me as a very good reason not to get a vasectomy.
