NCT05643131

Brief Summary

This study seeks to address accessible management of endometriosis-associated chronic pelvic pain by evaluating a novel device used in the home. The study is designed as a proof-of-concept single-arm pilot study, and the primary objective is to assess change in overall self-reported pelvic pain in people with endometriosis-associated chronic pelvic pain following the use of the Hyivy intravaginal device.
