AMH and polycystic ovary syndrome: In conclusion, the combination of a raised AMH >35 pmol/l and a raised FAI is 100% specific for a diagnosis of PCOS with type A phenotype and conversely a AMH <35 pmol/l with a normal FAI was 100% specific for the exclusion of PCOS with type A phenotype, though sensitivity was poor; thus, the additional routine measurement of AMH may be of value that would help in cases of diagnostic uncertainty for PCOS with type A phenotype.
