How old do I have to be to get a Vasectomy? and...?

I think at your age you should sit down and have a heart-to-heart talk with a Urologist to learn all the facts about a vasectomy... It is certainly a personal choice;however, you are so young and although you feel strongly that you will never want biological children, that may change one day. Reversals are not always able to be performed. I just encourage you to get all the facts prior to having this procedure done... In the US, I believe the legal age is 21... I'm not 100% sure, but I would think the youngest legal age would be 18.
