My dad got a vasectomy after me and my younger sister were born...over 10 years later he got it reversed. After getting it reversed he got a sperm count and found out the reversal did not work, so he got another one. About 2 months after the second reversal my mom got pregnant and they had my little brother. Unfortunately the'tubes'scarred over again because my mom hasn't been able to get pregnant since my little brother was born.

So there are a lot of things that can happen with reversals, and a man may need more than one, but it is always worth it. My brother is *literally* a genius.
