The Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network has been established to focus on a broader approach to the study of Interstitial Cystitis (IC)/Painful Bladder Syndrome (PBS) in men and women, and Chronic Prostatitis (CP)/Chronic Pelvic Pain Syndrome (CPPS) in men, than previously undertaken. Participants with some form or symptoms of IC or CP are being asked to join the Trans-MAPP Epidemiology and Phenotyping (EP) Study.
