A diaphragm keeps sperm from entering the uterus by covering the cervix. For added protection, spermicide is put into the bowl of the diaphragm and along its edges before it's inserted. The diaphragm is placed high into the vagina so it covers the cervix.
Why are diaphragms not used anymore?
The biggest problem with diaphragms is that they're not the most effective form of birth control. Diaphragms are about 94% effective against pregnancy with perfect use and 88% effective with real life use.
Dr. Schwab practised in Toronto from the 1920s to the 1980s; the rings are for determining the size of a diaphragm for contraception.
