About

This study aims to understand whether endometriosis lesions - and tumors that can arise in association with endometriosis - occur more often on one side of the pelvis than the other.

During surgery, doctors will record the exact location of each lesion to see if there is a consistent right- or left-sided pattern.

Understanding these patterns may help improve knowledge about how endometriosis develops (pathogenesis), and thus improve its treatment.
