A diaphragm is a flexible rubber cup that is filled with spermicide and self-inserted over the cervix prior to intercourse. The device is left in place several hours after intercourse. The diaphragm is a prescribed device fitted by a health care professional and is more expensive than other barrier methods such as condoms.
