The diaphragm is a birth control (contraceptive) device that helps prevent sperm from entering the uterus. The diaphragm is a small, reusable rubber or silicone cup with a flexible rim that covers the cervix.
Before sex, the diaphragm is inserted deep into the vagina so that part of the rim fits snugly behind the pubic bone. The diaphragm is most effective at preventing pregnancy when used with spermicide.
