What is The Diaphragm?
A diaphragm is a rubber dome-shaped device which the woman places over her cervix (opening to the uterus). A diaphragm is held in place by a woman's vaginal muscles. When combined with use of a spermicide (a gel which kills sperm), a diaphragm can provide a successful barrier to prevent sperm from entering the uterus (womb). The recommended diaphragm size is determined by your physician, at a custom clinic fitting. Diaphragms are generally considered to be between 86-94% effective. Among typical couples who use a diaphragm, about 16% will experience an accidental pregnancy in the first year of use. If the diaphragm is used consistently and correctly, about 6% will become pregnant. Diaphragm refittings should occur every one to two years, and after a significant loss or gain of weight, or pregnancy.
