While condoms are famously 98% effective with perfect use, the real-world failure rate tells a more complicated and urgent story about the gap between theory and practice.
Key Takeaways

Perfect Use Pregnancy Rates Interpretation
Statistically, even perfect condom use offers the reliability of a cautious optimist—it’s an excellent 98% effective, but that slim 2% margin means nature occasionally wins a very determined consolation prize.
