Diaphragm
The diaphragm is a dome-shaped, soft rubber disk with a flexible rim that’s placed inside the vagina before intercourse. It is used in conjunction with spermicidal cream or jelly. Spermicide is smeared on both sides of the diaphragm and acts as a barrier to prevent sperm from entering the uterus. When inserted properly, the diaphragm covers the cervix.
If you decide on this method of birth control, you’ll need to see your doctor to be fitted with a diaphragm and to learn how to insert and remove it yourself. The diaphragm is inserted up to four hours ahead of intercourse and must remain in place for at least six hours after intercourse has taken place. Also, if your weight changes by more than ten pounds, if you have pelvic surgery, or if you have a baby and want to resume contraception, you’ll need to be remeasured for a new diaphragm.
Additional spermicide must be inserted each time intercourse is repeated. Spermicides are available in foams, jellies, or creams and can be purchased in most drugstores without a prescription. When used correctly, the diaphragm, in combination with a spermicide, has an estimated eighty-two to ninety- seven percent success rate. There are no life-threatening risks or health hazards associated with using a diaphragm. Some women may find the spermicide slightly irritating, but changing brands may help.
For women who suffer chronic bladder or urethral (your-ree-thral) infections, diaphragms may aggravate these conditions.
