This self-administered, ring-shaped device delivers pre- and probiotics to help maintain a healthy vaginal microbiome.  

A balanced microbiome is critical to reducing uterine diseases and cervical and other gynecological cancers, where lower levels of the probiotic lactobacillus have been shown to increase cancer risk. 

This shelf-stable ring can be used even in low resource settings and delivers consistent doses of beneficial bacteria over a period of four weeks to maintain the vaginal microbiome and prevent precancer development.
