The Cervical Cap
Cervical caps are soft rubber cups with a round rim that fits snugly around the cervix. It is smaller than a diaphragm and uses suction to stay in place. The cap must be fitted by a health care professional before it can be prescribed for you (not every time you use it) and used with a spermicide. The cervical cap prevents sperm from entering the uterus. It is inserted into the vagina, anytime before intercourse.
