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. More effective than any other method of contraception, the chance of having an unexpected little surprise is extremely low. Vasectomies are 10 x more effective than tubal ligation and 20 x more effective than other forms of contraception.
