Birth Control and the Cervical Shield

What is the Cervical Shield?

The cervical shield, or Lea's Shield, is a one-size-fits-all, cup-shaped birth control device approximately the same size of the diaphragm. There is a valve on it that is designed to create suction during insertion to help it fit against the cervix.

How Is the Cervical Shield Used?

Spermicide should be put inside the cervical shield before insertion. It is inserted prior to sex and should not be removed for at least eight hours after intercourse. The shield can be kept in place for up to 48 hours.

Where Do I Get a Cervical Shield?

The cervical shield only comes in one size so fitting by your doctor is not necessary. It is available by prescription only.

How Effective Is the Cervical Shield?

The cervical shield is about 85% effective at preventing pregnancy.

Does the Cervical Shield Protect Against Sexually Transmitted Diseases?

No. Using a cervical shield and spermicide may not protect against some sexually transmitted diseases ( STDs), including HIV (the virus that causes AIDS). The male latex condom provides the best protection from most STDs.
