Identifying biomarkers for endometriosis using menstrual blood
Official title: RECHERCHE DE MARQUEURS DIAGNOSTIQUES ET PRONOSTIQUES DE L'ENDOMETRIOSE DANS LE SANG DES REGLES CHEZ LES FEMMES EN AGE DE PROCREER
Run by Institut National de la Santé Et de la Recherche Médicale, France · NCT06245512 · Data updated 2026-11-12
This study is trying to find markers in menstrual blood that can help diagnose and understand endometriosis in women aged 18-45, both those with the condition and those without.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include women aged 18-45 who have their period and reside or work in the Ile de France area, with some having a diagnosis of endometriosis.
✕Probably not a fit
Patients with autoimmune diseases or chronic conditions other than endometriosis may not benefit from this study.

What this trial studies
This observational study aims to identify diagnostic and prognostic biomarkers for endometriosis by analyzing menstrual blood, a readily accessible biological fluid. Women aged 18-45, both with and without endometriosis, will provide menstrual blood samples using a menstrual cup, with some participants also undergoing surgery for their condition. The study will compare the menstrual blood of women affected by endometriosis to those without the condition, as well as before and after surgical treatment, to identify significant differences that could aid in diagnosis and prognosis.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnostic methods for endometriosis, allowing for earlier and more accurate identification of the condition.
How similar studies have gone: While the approach of using menstrual blood for biomarker identification is relatively novel, similar studies have shown promise in identifying biomarkers for other conditions.
