While various contraceptive methods can be quite effective in preventing pregnancy, the truth is that birth control failure occurs more frequently than many people realize. Below is a breakdown of the average failure rates for different contraceptive methods. These rates are based on typical use, meaning they account for human error—using the method inconsistently or incorrectly. For methods that require hormonal intervention, it’s essential to follow the specific instructions provided to minimize the risk of unintended pregnancy.
When discussing hormonal contraceptives, it’s also crucial to consider their effectiveness and the ethical concerns surrounding their function. For instance, many hormonal methods alter the uterine lining to prevent implantation, which raises questions about their potential abortifacient properties. Here’s a closer look at how each method works and the associated risks or side effects.

| Cervical Cap | A soft rubber barrier that covers the cervix to prevent sperm from entering the uterus. | 12% (higher after childbirth) | None unless allergic |
