The diaphragm is a cervical barrier type of birth control. It is a dome shaped, shallow cup with a flexible ring made of latex. When it is in the vagina, it covers the cervix.
Diaphragms prevent pregnancy by preventing sperm from joining with an egg. The diaphragm must be used with spermicide cream or jelly In order to be as effective as possible. The diaphragm must be inserted sometime before sexual intercouse, and remain in the vagina for 6 to 8 hours after a man's last ejaculation. Depending on usage and storage conditions, a latex diaphragm should be replaced every one to three years. Silicone diaphragms may last up to ten years.
If women always use the diaphragm as directed, 6% will become pregnant each year.
If women don't always use the diaphragm as directed, 16% will become pregnant each year.
