i'm thinking this is the same one as above but i'll answer any way just in case.
No, you do not need to use birth control after you get your tubes tied. To have this done they make a small incisioin just below your belly button and go in and tie them. You are effectively sterilized for the rest of your life. There are some risks, just like birth control. This is why they make you sign a form before you have the procedure done. If you have any questions ask your doctor because this procedure will affect you for the rest of your life.
I had it done 5 years ago and have not used any form of bc.
