Cervical barriers (CBs) are safe, effective, woman-controlled contraceptives that prevent pregnancy by covering the cervix. Research is underway to see if they can also protect women against HIV and other sexually transmitted infections (STIs).

This page provides links to information about cervical barriers and current research.
