Birth Control - Cervical Cap:
A
cervical cap is a latex, thimble-shaped device that is
inserted into the vagina and fits snugly over the cervix.
Suction keeps the cap in place. A cervical cap provides a
barrier to block sperm from entering the uterus and prevents
fertilization. After intercourse, it should be left in place for
8 hours. A cervical cap is used with spermicidal jellies or
creams that kill sperm.
