Birth Control Barrier Methods (cont.)
IN THIS ARTICLE
The cervical cap is a soft cup-shaped latex device that fits over a woman’s cervix. It is smaller than a diaphragm and may more difficult to insert. It must be fitted by a physician because it comes in different sizes. Its use is derived from the eighteenth- to twentieth-century European practice of placing the rind of a lemon or small orange against the cervix prior to intercourse. The groove which is found along the inner circumference of the rim of the cap provides a seal between the rim and the base of the cervix. Spermicide is needed to fill the cap one third full prior to its insertion. It may be inserted as long as 8 hours prior to intercourse, and it can be left in place for as long as 48 hours. A cervical cap acts as both a mechanical barrier to sperm migration into the cervical canal and as a chemical agent because it is used with of spermicide.
