How effective are diaphragms in preventing pregnancy?

ANSWER

How well a diaphragm prevents pregnancy depends a lot on whether you use it correctly. Six out of 100 women will get pregnant with the diaphragm if they use it perfectly every time. Most people make mistakes sometimes, so the typical rate is more like 12 to 18 out of 100. That’s more effective than condoms or other barrier methods, but less effective than sterilization, intrauterine devices (IUDs), or birth control pills.
