Cervical Cap

What is a cervical cap?

A thimble-shaped, soft rubber cap with a round rim that is fitted by a health professional to fit around your cervix. Currently, the cervical cap is not available in the United States.

How is it used?
The cap is placed inside the vagina to cover the cervix. It is recommended that spermicide be added to increase the effectiveness of this method.

The cervical cap acts by blocking the entrance to the uterus; the spermicide acts by killing and immobilizing the sperm, preventing it from fertilizing the egg.

The cervical cap must be left in place for at least six hours after last intercourse before removing.

Does it protect against STIs?
NO! The cervical cap protects against certain STIs, including gonorrhea and chlamydia, but does not protect against others such as HIV and herpes.

Does it protect against pregnancy?
Yes.

What are the chances of getting pregnant while using a cervical cap?

  • Typical use: 20 percent

  • Perfect use: 9 percent
Advantages for women while using a cervical cap?
  • Unlike the diaphragm, the cervical cap protects against pregnancy for two days (48 hours) and for multiple acts of intercourse within that time frame.

  • When placed appropriately, the cervical cap is often not felt by either partner during sexual intercourse.
Disadvantages for women while using a cervical cap?
  • The cervical cap is more difficult for women to learn to insert and remove than the diaphragm.

  • If worn for more than two days (48 hours) you run the risk of:
    • Toxic shock syndrome.

    • Unpleasant vaginal odor.

    • Unpleasant vaginal discharge.
  • Mild allergic reactions to the rubber or spermicide occasionally occur.
Things you should know:
  • Cervical caps must be fitted by clinicians and purchased from a drugstore or clinic.

  • Cost of purchase is covered by Medicaid.
