A diaphragm is a birth control method with a medium failure rate. It’s a soft rubber dome that fits over the cervix – the neck of the womb. It blocks sperm from getting into the womb. It works best if used with a spermicide.

You have to be examined by a doctor – a pelvic exam, to get the right size to fit your cervix. After that, you put the diaphragm in yourself before you have sex. Using it is similar to putting in a female condom.

You will need to regularly test your diaphragm for leaks; if there are any, it will decrease its effectiveness.

You will need to leave your diaphragm in for at least six hours after having sex, but no longer than 24 hours. If you have sex again during this period, apply more spermicide before having intercourse.

You will have to put in your diaphragm before you are going to have sex. Ideally, before you even get aroused, allow for good placement.
Diaphragms can be a bit tricky to use, which is why with typical use, it’s 83-84 percent effective: 16% in perfect use and 17% in typical use.
