In plain language

Small extracellular vesicles from menstrual fluid, collected with a menstrual cup, were compared between 8 women with self-reported, surgically diagnosed endometriosis and 9 self-reported controls. Over 5,000 proteins were identified, most at lower levels in endometriosis, and the authors suggest the vesicle cargo may contribute to the disease and could be explored for earlier detection.

What it means

Vesicle proteins in menstrual fluid may play a part in endometriosis, adding to a growing set of signals. These discovery findings need validation in larger groups.

What it does not show

Seventeen women with self-reported diagnoses, established disease and cup-collected fluid; it suggests biology to study, not an early detection test.
