The Cervical Barrier Advancement Society (CBAS) aims to raise the profile of cervical barrier methods, including diaphragms, caps, female condoms, and other devices, and to share the latest information and resources related to these methods.
What are cervical barriers?
Most people think of cervical barriers primarily as the diaphragm and cervical cap, but the category also encompasses female and male condoms, the sponge, and microbicides, among others. Cervical barriers are physical or chemical substances that prevent pregnancy and in some cases reduce the spread of STIs, including HIV. They do not include hormonal contraceptive methods. For more information about the range of cervical barrier methods, see Cervical Barrier Methods.
