OBJECTIVE: To determine whether women with polycystic ovary syndrome (PCOS) would be distinguishable from women with late onset congenital adrenal hyperplasia (LOCAH) on the basis of antimullerian hormone (AMH) levels.
STUDY DESIGN: PCOS was diagnosed in 170 women; 105 were polycystic ovary morphology (PCOM)+/oligo-anovulation (OA)+/hyperandrogenism (HA)+, 40 PCOM+/OA-/HA+ and 25 PCOM-/OA+/HA+. These three groups were compared with 25 women in whom LOCAH was diagnosed.
RESULTS: The mean serum AMH levels were 8.12±1.85ng/ml in PCOM+/OA+/HA+ group, 5.34±1.82ng/ml in PCOM+/OA-/HA+ group, 3.02±1.76ng/ml in PCOM-/OA+/HA+ group and 4.43±1.29ng/ml in LOCAH group. The mean AMH level in PCOM+/OA+/HA+ group was approximately twofold higher than the mean AMH level measured in LOCAH group (p<0.001). Women with PCOM+/OA-/HA+ had higher serum AMH levels than those with LOCAH, women with LOCAH had higher serum AMH levels than those with PCOM-/OA+/HA+ but these differences were not statistically significant (p>0.05).
CONCLUSIONS: AMH is not suitable for distinguishing LOCAH from all types of hyperandrogenic patterns of PCOS, but is only applicable for a specific subtype, such as PCOS patients with three main diagnostic criteria. Therefore, ACTH stimulation test remains an essential clinical tool to diagnose LOCAH.
