AMH and obesity due to melanocortin 4 receptor deficiency: Since obesity is known to be associated with increased circulating asprosin levels, and individuals with higher BMI values also show lower AMH concentrations compared to those with anormal BMI values, the results discussed above should be confirmed in a more homogeneous group, despite the fact that in the present group, BMI values did not differ significantly between the compared subgroups and was, thus, unlikely to confound the results.
