The Asymmetry Distribution of Endometriotic Lesions: Italian Multicenter Study
The Asymmetry of Endometriotic Lesions as Demonstration of the Theory of Menstrual Reflux and Anatomical Niches: Italian Multicenter Study by the ETIC Group

Brief summary (registry, in English)
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.
