Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to determine if some women with dysmenorrhea (painful periods) are at higher future risk of developing chronic pelvic pain (CPP) and if oral contraceptives (OC) can be used to reverse this chronic pain risk. Investigators will examine whether dysmenorrhea produces CPP via repetitive cross organ sensitization (COS) episodes. The use of cyclical OCs to eliminate dysmenorrhea is expected to reduce COS and decrease the risk of developing CPP.
