How Effective Is Birth Control?
Birth control effectiveness depends on the method you use and how well you use it. Some methods are over 99% effective, while others work better only when used perfectly. Understanding these differences helps you choose the right option for your needs.
How Effective Are Birth Control Pills?
Birth control pills are 99% effective with perfect use. This means taking the pill at the same time every day without missing any doses. However, most people don't use them perfectly.
With typical use, the pill is about 93% effective. That means roughly 7 out of 100 people using the pill will get pregnant each year. Missing pills, taking them at different times, or certain medications can reduce how well they work.
Most Effective Methods
IUDs and implants are the most effective reversible birth control options. Both are over 99% effective and work for 3 to 10 years depending on the type. These methods are 20 times more effective than pills because you don't have to remember to do anything daily.
The birth control shot (Depo-Provera) is 99% effective with perfect use but drops to 94% with typical use. The patch and ring are 91% effective with typical use.
Do You Ovulate on Birth Control?
Most hormonal birth control methods stop you from ovulating. The hormones prevent your body from releasing an egg each month. No egg means pregnancy cannot happen.
Combined pills (with estrogen and progestin) reliably stop ovulation when taken correctly. Progestin-only mini-pills may not always stop ovulation, but they thicken cervical mucus to block sperm. Missing pills can allow ovulation to occur.
Tips for Better Effectiveness
Take your pill at the same time every day. Set a phone alarm as a reminder. If you often forget pills, consider a longer-acting method like an IUD or implant. Always tell your doctor about other medications you take, as some can reduce birth control effectiveness.
When to Talk to Your Doctor
Speak with a healthcare provider if you're unsure which method is right for you. They can help you weigh the options based on your health, lifestyle, and personal preferences. The best birth control is one you'll use correctly and consistently.
