While a 9 in failure rate seems high for these hormone-based methods, it's important to remember that this rate takes into account user error.
Because women don't always take the pill as directed or replace their patches and rings on schedule, failure rates for these methods are higher than they would be with perfect use. There are some birth control methods that require less action on the part of women; for example, once you get an IUD, there's nothing you have to do to make sure it's doing its thang, except for remembering to get it replaced every years depending on the type you get.
