The Women's Health Research Unit is conducting a study to determine if the bacteria in the urinary tract contribute to Overactive Bladder Syndrome (OAB).


Why is this study being done?

Currently, the underlying causes and biology of Overactive Bladder Syndrome are largely unknown. Many women suffer from this condition which can significantly affect a woman's happiness and lifestyle. In order to treat something effectively, doctors and scientists must understand what causes it. This study seeks to better understand how the urinary microbiome affects OAB with the hopes of improving treatment practices for women who suffer from this condition. 

Purpose of this study:

  • To identify if there is a shift in the urinary microbiome as a woman transitions from pre- to post-menopause. 
  • To determine if there is a significant difference in the quantity and types of bacteria present in the urinary microbiome of women with OAB compared to women without OAB, independent of menopausal status. 
  • To determine if the urinary microbiome remains stable or varies over time. 


You may be eligible for this study if:

  • You are a woman between 55-80 years of age
  • Are in good general health
This study seeks women with normal bladder function AND women with overactive bladder syndrome. 


Qualified participants will be compensated up to $40 for time and travel for this study.
