Birth control options: Things to consider

How do the different birth control options work?

Various types of birth control work in different ways. Birth control methods may:

  • Prevent sperm from reaching the egg
  • Inactivate or damage sperm
  • Prevent an egg from being released each month
  • Alter the lining of the uterus so that a fertilized egg doesn't attach to it
  • Thicken cervical mucus so that sperm can't easily pass through it
