I wasn't sure whether to start a new thread or necro-bump.
So, bump.
You guys are insane to not have this done.
It costs about $600. It's covered by most medical plans. The current procedure is 95% reversible. It is absolutely bombproof in a court of law. Your sexdrive goes up, as does your test level. Plus, you can relax about ever knocking a girl up. Ever.
I had this done five years ago, when my late wife first got sick. It would have been bad for her to get pregnant, and my feeling that I didn't want to raise a kid alone quickly became the feeling that I didn't want a kid, ever. This was a no-brainer.
It has come a long way since then and even back then it wasn't bad. For a couple of days it felt like I'd taken a baseball in the nuts about an hour earlier. I was having sex three days later and shooting blanks when I went back in a couple of weeks.
Guys screw this up by not going in for their 6-month and 1-year followup. It can grow back in that time; I've read that the failure rate is about 1 in 4,000 and my understanding is that even when that happens, there's so much scar tissue at the juncture (the cauterized ends have to find each other and then re-attach) that your sperm count is effectively low enough that the odds of conception are practically zero. It might have happened to your father or someone your father knows, but it's a totally new procedure, now.
If you're still good after a year, there is zero -- zero -- chance of ever conceiving unless you have a surgical reversal done. And if you ever get paranoid, there's now an OTC test available.
In case you're reading this and you're 12 years old or a drooling moron: they do not cut your nuts off. They make a tiny incision. Sex feels exactly the same. Your semen looks the same.
And if you're a grown man, you get to keep your house and laugh in the face of the woman who decides that since you have more money than the other guys she's banging, the kid she's carrying must be yours. Don't laugh; I know a guy. And I'm sure it will eventually happen to me.
You still need to use a condom to protect against STD's. (I can't believe I had to type that sentence but some people are morons.) But with a vasectomy the chances of an accidental pregnancy -- or a vengeful psycho -- destroying your life are zero.
