A diaphragm is a birth control device that blocks sperm from
fertilizing an egg. It is made of rubber and shaped like a dome. It fits inside
a woman's vagina and covers the
cervix (the opening of the uterus); a firm, flexible
rim keeps it in place. A diaphragm is always used with a sperm-killing cream or
jelly (spermicide) to prevent pregnancy.
With good care, a diaphragm
should last 1 to 2 years. You should be refitted for a diaphragm if you gain or
lose a lot of weight, have abdominal surgery, or have a baby.
