• W4308136693 abstract "Abstract Polycystic ovary syndrome (PCOS), an endocrine disorder that affects 10% of women worldwide. In 1990, the NIH established the first consensus on diagnostic criteria for PCOS which included chronic anovulation with clinical and/or biochemical hyperandrogenism, after the exclusion of related disorders. Traditionally the assessment of hyperandrogenism included serum studies of total testosterone (TT), free testosterone (FT), and dehydroepiandrosterone sulfate (DHEA-S), and physical exam assessing hirsutism using the modified Ferriman-Gallwey (mFG) score. The most recent 2018 International Guidelines suggest the measurement of DHEA-S can be considered if TT or FT are not elevated, but probably provide limited diagnostic value. We evaluated the diagnostic utility of TT, FT, DHEA-S and hirsutism in a large prospective cohort of PCOS women. Subjects presented to tertiary-care specialty clinics with symptoms of androgen excess in Birmingham, Alabama and Los Angeles, California from 1987-2010. Clinical hyperandrogenism was assessed using the mFG score, and hirsutism was defined as mFG &gt;4. Participants underwent serum studies to assess for hyperandrogenemia and exclude other causes of hyperandrogenism. Fasting blood samples were obtained on cycle days 3 through 8 of a spontaneous or progesterone-induced vaginal bleed for measurement of TT, FT and DHEA-S. Elevated serum androgens were defined as values exceeding the laboratory reference range or greater than the 95th percentile of reported values. Subjects were considered to have oligomenorrhea if they reported &gt;35 day cycles, &lt;10 bleeds per year or reported being eumenorrheic but were confirmed non-ovulatory with a luteal phase progesterone &lt;4 ng/mL. One thousand six hundred and ten women and adolescents (n=1610), aged &gt; 14 years, were diagnosed with PCOS by NIH Criteria and included. Of these 1610 subjects, 39.3% (n=643) were diagnosed with PCOS based upon an elevated TT and FT with oligomenorrhea; 23.9% (n=384) based upon an elevated TT, normal FT and oligomenorrhea; 11.3% (n=182) based upon an elevated FT, normal TT and oligomenorrhea; 1.1% (n=17) based upon oligomenorrhea with normal TT, normal FT and elevated DHEA-S; and 23.9% (n=384) based upon normal serum androgens, oligomenorrhea, and hirsutism (mFG&gt;4). Results suggest that the diagnosis of PCOS is rarely made based upon elevated DHEA-S in the setting of normal TT and FT. Most women had elevated TT and/or FT values, but still a significant proportion (23.9%) of women were diagnosed with PCOS based upon hirsutism in the context of normal serum androgens. Thus, an assessment of hirsutism, which is both timely and inexpensive, is a strong predictor and valuable tool in diagnosing PCOS, reserving DHEAS when better measures of hyperandrogenism are not diagnostic.
