    Abstract:
    Polycystic ovary syndrome (PCOS) is characterized by various endocrine and metabolic abnormalities, whose mutual associations and symptoms are still not clear. In the present study, fifteen PCOS patients and fifteen controls, matched for age and body weight, were investigated. Endocrine profiles were evaluated by the nafarelin and the adrenocorticotropin (ACTH) test. Insulin sensitivity was determined by an intravenous insulin tolerance test. Patients showed a significant predominance of abdominal adiposity [waist-to-hip ratio (WHR), 0.86 +/- 0.05 vs. 0.79 +/- 0.04] with markedly higher fasting insulin levels (+75%) and reduced insulin sensitivity (-37%). Fasting insulin, testosterone and free androgen index were positively correlated with the body mass index (BMI). In contrast, insulin sensitivity and BMI were inversely correlated in patients only. In the nafarelin test increases of 17-OH-progesterone and androstenedione were higher in patients and positively correlated with fasting insulin levels. Lipoprotein profiles showed trends towards higher triglycerides, lower HDL-cholesterol and a preponderance of small, dense LDL in patients. In PCOS higher triglycerides and lower HDL cholesterol were correlated with insulin sensitivity. It is concluded that PCOS patients show metabolic abnormalities combined with a more adroid type of adiposity when compared to cyclic controls of similar BMI.
