Learning About How Well Birth Control Options Work
Before choosing birth control, you may want to compare how well each option works. Some birth control options
prevent pregnancy better than others.
Comparing birth control options
How well each birth control option works is given as a percentage. The closer the percentage is to 100%, the
better that option works to prevent pregnancy. This is during the first year of typical use. Using no birth
control works about 15% of the time.
