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.
Updated CBAS Diaphragm and Cervical Cap and Female Condom Bibliographies
We are excited to share these updated resources with the CBAS community. Our bibliographies of the literature on diaphragms and cervical caps and on the female condom include the latest peer-reviewed, published articles (updated through May 31, 2013). Both bibliographies can be downloaded by following the links below.

MIRA Diaphragm Trial Results
The Methods for Improving Reproductive Health in Africa (MIRA) trial found no significant difference in the rate of new HIV infections between women who received the diaphragm plus lubricant along with male condoms and those who only received male condoms. Therefore, the results do not support the addition of the diaphragm to current HIV prevention strategies. To date, condoms remain the only proven barrier method for HIV prevention. This means there is still an urgent need for continued investment and research into current and new HIV prevention methods that give women and girls the power to protect their health. Read more...

Why is research on cervical barriers important?
The HIV pandemic disproportionately affects women and girls. Cervical barriers are under investigation as a female-controlled method of birth control that may reduce sexually transmitted infections (STIs), including HIV. Click here for information about the research being undertaken in this area.
