Question: 1 / 400

What is the failure rate of the NuvaRing in preventing pregnancy?

Less than 5%

Less than 1-2%

The NuvaRing, a form of hormonal birth control, has a very effective track record when used correctly. The failure rate of the NuvaRing in preventing pregnancy is about 0.3% with perfect use, which translates to less than 1-2% for typical use. This means that for every 100 women using the NuvaRing for one year, fewer than 2 will become pregnant if they use it as directed. The effectiveness stems from its consistent release of hormones to prevent ovulation and alter the uterine lining.

When evaluating the other options, less than 5% indicates a broader range that may include other contraceptive methods with less efficacy. Approximately 10% is significantly higher than established studies and real-world data suggest for typical use. About 3-4% is also above the recognized failure rate for the NuvaRing. Understanding these distinctions is crucial in advising patients on their contraceptive choices and ensuring they use effective methods.
