Suspected ontogeny of a recently described hypo-androgenic PCOS-like phenotype with advancing age.


 

Published in Endocrine.

BACKGROUND: A recent report described a new PCOS-like phenotype in lean older infertile women, and was characterized by high age-specific anti-Müllerian hormone (AMH) but hypo- rather than the expected hyper-androgenism. The hypo-androgenism was, furthermore, characterized of, likely, adrenal origin and autoimmune etiology.

PATIENTS AND METHODS: We extracted data on 708 consecutive infertility patients, and separated them into three age-strata, <35, 36-42, and >42 years. In each stratum, we investigated how levels of anti-Müllerian hormone (AMH) and testosterone (T) interrelate between high-AMH (AMH ≥ 75th quantile) and normal AMH (25th-75th quantile) and low-T (total testosterone ≤19.0 ng/dL), normal-T (19.0-29.0 ng/dL) and high-T (>29.0 ng/dL). High-AMH cycles were presumed to reflect PCOS-like patients. Routine in vitro fertilization (IVF) cycle outcomes and clinical phenotypes of patients were then compared between groups with AMH and T as statistical variables.

RESULTS: This hypo-androgenic PCOS-like phenotype already exists in age stratum

CONCLUSIONS: Here investigated new PCOS-like phenotype demonstrates features compatible with what under Rotterdam criteria has been referred to as PCOS phenotype-D. If confirmed, the observation that the ontogeny of this phenotype already at young ages is, likely, driven by adrenal autoimmunity, supports the position of the androgen excess and PCOS society that the etiology of phenotype-D differs from that of classical hyper-androgenic PCOS of mostly ovarian etiology.
