Contraceptive Effectiveness

Contraceptive effectiveness refers to how well a birth control method prevents pregnancy. It's typically measured by the number of pregnancies that occur among 100 women using that method over a year. For example, if 1 out of 100 women become pregnant with perfect use, the method is considered very effective. However, real-world use may have slightly higher failure rates due to inconsistent or incorrect use. Understanding effectiveness helps individuals choose a method that best fits their needs and lifestyle, balancing protection with convenience.
