We need 1000 bladders for this critical research to succeed and you can help us get there!

Urine is not sterile. This was only discovered in 2014 and we have a lot of catching up to do.

Scientists still don’t know a lot about the female urinary microbiome or why some women get urinary tract infections (UTIs) while others don’t. We’re looking to change that and improve the lives of millions of women. 

UTI affects around 404 million people globally every year (85% in females), and is one of the biggest contributors to the antimicrobial resistance crisis. 

The Bladder Biome Project aims to improve the understanding of recurrent UTI, with the ultimate goal of helping to change the ways in which recurrent UTI is diagnosed and treated. 

How can you help us close the research gender gap? 

We’re calling on female entrepreneurs to activate their networks to help us reach those who could benefit from this research. US mainland based people with female urinary anatomy who experience recurrent UTI are welcome to apply to join the study.

To make it easy, we’ve provided assets and language you can share with your own audience. You’re also welcome to join the study yourself!

    After recovering from a recurrent UTI that led to long-term chronic symptoms, Melissa founded Live UTI Free, a patient research and education organization focused on improving outcomes by sharing crucial information to help others find better UTI testing and treatment.

    Through her own PhD research, her work with the patient community and the extensive research of her team, the organization has developed an expansive network of researchers, clinicians and like-minded organizations. Melissa is always happy to hear from anyone working to address the gaps in women’s health research.
