New publication on Caya diaphragm in Niger

25 February, 2022

Dear colleagues,

In a setting with one of the lowest rates of family planning use in the world, might a revamped version of a centuries-old contraceptive method fill a need?

Diaphragms have never been widely available in West Africa. Past research has demonstrated the single-size Caya diaphragm to be a safe and effective barrier method of nonhormonal, on-demand, self-care contraception with features that improve upon the design of traditional diaphragms. In Niamey, Niger, from 2019-2021, USAID's Expanding Effective Contraceptive Options (EECO) project introduced the Caya diaphragm and studied acceptability, use, and programmatic considerations. The results of this study with Caya diaphragm adopters, men, and family planning providers are available in a new article published by Global Health: Science and Practice. Findings from the pilot study indicate significant potential for the Caya diaphragm to expand contraceptive options in a meaningful way in Niger and similar settings if made more widely available.
