Design
Observational study
Subjects
Patients with endometriosis and healthy fertile controls (numbers not stated in the abstract); a mouse model of endometriosis
Dose used in the study
Not stated in the abstract; no treatment was given
Duration
Not stated in the abstract
What was measured
Mass spectrometry of endocannabinoids in plasma, endometriosis lesions and endometrium; gene expression and immunohistochemistry of CB1 and CB2 receptors.

What the authors reported

Plasma endocannabinoids did not differ between patients and controls, but palmitoylethanolamide was significantly higher in endometriosis lesions than in patients' own endometrium, while CB2 receptor expression was lower in lesions. In mice with endometriosis, PEA was higher in plasma and lesions than in sham controls.

Limits of this study

A tissue measurement study in people and mice; it did not test palmitoylethanolamide as a treatment and cannot show effect in people treated in practice. Sample sizes are not given in the abstract. Funding and conflicts not stated in the abstract.
