Normal Anti Mullerian Hormone (AMH, Antimullerian Aormone) levels (values)  by age

In an excellent article in Fertility and Sterility the  median levels for Antimullerian Hormone were  provided by analyzing the age specific  database of a large blood laboratory. As we all know AMH is a good predictor of fertility reserve ( the higher the better). But what is a normal value? the obvious response is that it varies with age and its values decline with age. Thanks to this article we now get a good perspective on how to  interpret this test.  As most screening tests  Antimullerian Hormone (AMH)  is very informative when it is very low ( =less fertile) .
