Pelvic Floor Research Group

Improving prevention and treatment of women’s pelvic floor disorders.

The Pelvic Floor Research Group (PFRG) is an internationally recognized, interdisciplinary research group working to improve the understanding and treatment of pelvic floor disorders. Our goal is to identify risk factors for developing pelvic floor disorders, work with high-risk women to prevent them, and provide the most effective and newest treatments for pelvic floor dysfunction.
