Irreversible (permanent) methods of birth control prevent pregnancy for the remainder of one's natural life. Sterilization permanently prevents conception and pregnancy by surgically altering, blocking or removing the reproductive organs so that sperm and eggs never make contact. Sometimes "irreversible methods" can be reversed, but such attempts are tedious and costly, and success is never guaranteed.
Before agreeing to use a permanent method to prevent pregnancy, you need to be sure you do not want any more children.
