diaphragm:
1. A method of contraception used by women. 2. A contraceptive device consisting of a dome-shaped, spring-rimmed, latex cup filled with a spermicidal jelly or cream and placed in the vagina to fit over the cervix and prevent sperm from entering the uterus; it should be inserted up to 2 hours prior to intercourse and left undisturbed for 6 to 8 hours subsequently (the spermicide is only effective for 12 hours and needs at least 6 hours to kill sperm). Diaphragms are available in sizes ranging from 5.5 to 10 centimeters in diameter; since they can slip during intercourse they are rated as only 80-95% effective; if used in conjunction with a spermicidal jelly or cream , it helps prevent infection and the spread of STDs and AIDS. The diaphragm was invented in 1882.
