AMH and obesity due to melanocortin 4 receptor deficiency: Furthermore, AMH was positively correlated with E2, and the free androgen index during adolescence, as well as during the reproductive phases.[24] A positive correlation between AMH and testosterone has also been reported, although controversy persists.[25,26] Women of reproductive age with obesity were previously reported to have AMH concentrations that were 23.7% lower than those with a BMI ≤ 25 kg/m2 (2.9 ng/mL vs 3.8 ng/mL); BMI was inversely associated with AMH.[27] However, other studies have stated that AMH has no correlation, or a positive correlation, with BMI.[24,28,29]
