How does it work?

The diaphragm / cap is a flexible dome made of rubber or silicone, which is covered with spermicide gel and put into the vagina to cover the cervix (the entrance to the womb). It prevents sperm from entering the womb and meeting an egg. Sex should occur within three hours of insertion and it must be left in place for at least six hours after intercourse.
