AMH and endometriosis: In their case–control study, Streuli et al. did not identify a significant difference in the AMH levels between cases (various endometriosis phenotypes and disease stages) and controls (other, benign gynecological pathologies) [cases: 3.6 ± 3.1 ng/mL, controls: 4.1 ± 3.4 ng/mL, mean difference: 0.45 (95% CI −0.02 to 0.96) ng/mL, p = 0.06], with the only exception being patients with previously operated OMA [44].
