Summary

This study will investigate whether exposure to persistent organic pollutants (POPs) like dioxins and PCBs is linked to more severe endometriosis. Researchers will analyze blood samples from 650 women with endometriosis living in the Ile-de-France region of France. The goal is to better understand environmental risk factors for this painful condition.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could clarify whether certain environmental pollutants worsen endometriosis, potentially guiding future prevention or treatment strategies.
What could go wrong
This is an observational study, not a treatment trial. It can only show a link, not cause and effect. Results may not apply to all populations.

Inclusion Criteria: * ComPaRe participants ⩾ 18 years old. All ComPaRe participants are at least 18 years of age, so our research participants will all be adults. * Having declared in ComPaRe that they had endometriosis * Living in the Ile-de-France region (departments 75, 77, 78, 91, 92, 93, 94 or 95); * Have given electronic consent stating: "By checking this box, I agree to be solicited for research outside ComPaRe"; This criterion is collected at the time of ComPaRe registration, when consent is collected. Participants can withdraw this consent at any time on their secure personal online account on the ComPaRe platform. * Aged ≤ 45 years to avoid including premenopausal or menopausal women; * In possession of MRI images used to diagnose their endometriosis (CD-ROM) that are no more than 5 years old; * Enrolled in or benefiting from a social security scheme. Exclusion Criteria: * \- People with contraindications to blood sampling will not be included in this research: * Known severe anemia * Hemophilia/coagulation disorders/anticoagulant use * People with HIV, HBV or HCV will not be included in this study due to the risk of BSE (Blood Exposure Accident). * Based on factors that may disrupt lipid dynamics and lipid pollutants, the following individuals will not be included: * Pregnant and breast-feeding women * People suffering from any of the following diseases: * Cancer * Morbid obesity (BMI\>40) * Non-alcoholic steatohepatitis (NASH) * Persons under court protection/guardianship/guardianship will not be able to participate in this research.
