Abstract
Polycystic ovary syndrome (PCOS), defined as the combination of oligoanovulation and
hyperandrogenism, affects more than 5 % of women of reproductive age. Insulin resistance
and hyperinsulinemia appear to play an important role in its pathogenesis. Here, we
will present a characterization of a PCOS cohort from North Rhine-Westphalia in Germany.
Clinical features, family history as well as endocrine and metabolic parameters were
prospectively recorded from 200 successive patients. All patients were evaluated for
insulin resistance and β-cell-function by oral glucose tolerance test. Patient data
were compared with those of 98 age-matched control women. PCOS patients showed significantly
higher BMI, body fat mass and androgen levels as well as impaired glucose and insulin
metabolism. A positive family history of PCOS and diabetes was more frequent in PCOS
patients. Insulin resistance (71 %) was the most common metabolic abnormality in PCOS
patients followed by obesity (52 %) and dyslipidemia (46.3 %), with an incidence of
31.5 % for the metabolic syndrome. C-reactive protein and other cardiovascular risk
factors were frequently elevated even in young PCOS patients. While the clinical characteristics
and endocrine parameters of this German PCOS cohort were heterogeneous, they were
comparable to those from other Caucasian populations.
