context_page_description: The cervical cap is a form of barrier contraception. A cervical cap fits over the cervix and blocks sperm from entering the uterus through the external orifice of the uterus, called the os.
context_section_description: Individuals who wish to use a cervical cap are screened by a health care provider to determine if a cervical cap, or one brand of cap, is appropriate for them.  If a cap is determined to be appropriate, the provider will determine the proper size.  The user must be refitted after any duration of pregnancy, whether the pregnancy is aborted, miscarried, or carried to term through vaginal childbirth or caesarean section.
  Several factors may make a cap inappropriate for a particular woman.  Women who have given birth may have scar tissue or irregularly shaped cervixes that interfere with the cap forming a good seal.  For some women, available sizes of cervical caps do not provide a correct fit.  Also, cavity rim caps are not recommended for women with an anteflexed uterus. In infrequent cases a woman may have a long vagina but short fingers and thus may not be able to place the cap correctly.  Overall, 80% to 85% of women who want caps can be fitted without issues.
  The rim cap should be such that the rim tucks into the fornix snugly and evenly so as to maintain good suction to hold it in place.
  In some countries, some devices (such as the Lea's Shield) are available without a prescription.
