Why should I get a vasectomy?

Elective vasectomy offers a much safer, faster and effective alternative to other methods of long term birth control such as the female alternative, tubal ligation. With a 99% effectiveness rate, the chance of having an unexpected little surprise is extremely low. Vasectomies are 20 x more effective than tubal ligation and 100 x more effective than other forms of contraception.
