Cervical Cap

Overview of Cervical Cap

Silicone cap that is filled with spermicide prior to insertion, then placed over the cervix to prevent sperm from entering the uterus and potentially fertilizing an egg. There is currently one type of cervical cap available in the United States: the FemCap. Requires a visit with a healthcare provider for a prescription.

How It Works

The FemCap is a bowl-shaped cap that adheres to the cervix through suction and is inserted by the user. It is available in 3 sizes requiring a fitting by a clinician. The FemCap should remain in the vagina at minimum 6 hours after ejaculation, but it can be worn up to 48 hours after intercourse and can be removed by gently pulling on the loop attached to it. Because it is made of silicone, it can be boiled for cleaning in between uses.
