The diaphragm is a "barrier" method of birth control. That means when inserted into the vagina, it will cover the cervix and will block the sperm from entering the uterus. It is made of latex and has a firm yet flexible ring that folds in half so you can slide it in the vagina. It requires an exam and must be fitted to your body. You should always use spermicide gel or cream with the diaphragm. It must be left in place after sex for at least 6 hours. If you leave it in more than 30 hours, it could cause Toxic Shock Syndrome - a serious bacterial infection that could make you very sick. The diaphragm must be inserted EVERY time you have sex. It is 88% effective .
