In terms of the most effective birth control method, implants and intrauterine devices (IUDs) are the most effective at preventing pregnancy, as they work 99 percent of the time. In comparison, birth control injections are 94 percent effective, while birth control pills are 91 percent effective. Natural methods, such as the withdrawal method, are approximately 70 to 80 percent effective.
