The diaphragm is a barrier method of birth control.[3] It is moderately effective, with a one-year failure rate of around 12% with typical use.[4] It is placed over the cervix with spermicide before sex and left in place for at least six hours after sex.[5][6] Fitting by a healthcare provider is generally required.[
