title: Evaluation of adipocytokine levels and vascular functions in young aged to middle aged men with idiopathic hypogonadotrophic hypogonadism.
abstract: OBJECTIVE
  Hypogonadism has major effects on the urogenital system, in addition to other systems, the cardiovascular system in particular. There have been few studies conducted on markers of atherosclerosis, such as flow mediated dilatation (% FMD), carotid intima-media thickness (CIMT) and adipocytokine levels in idiopatic hypogonadotropic hypogonadal (IHH) males mostly in adult patients. The aim of this study was to evaluate the relationship between androgens and adipocytokines and parameters of vascular functions in hypogonadal men.
  
  
  METHODS
  The study population consisted of 11 treatment naive IHH patients (group 1) and 15 age-matched healthy control males (group 2). A fasting blood sample was obtained for leptin, adiponectin and resistin. The endothelial functions were evaluated by studying % FMD and CIMT by high resolution B-mode ultrasound.
  
  
  RESULTS
  No significant differences in age, body mass index, systolic and diastolic blood pressure were recorded between the two groups. The leptin level was significantly higher in group 1, whereas adiponectin and resistin levels were same between two groups. There was a negative correlation between total testosterone and carotid intima-media thickness (r=-0.656, p=0.008), and a negative correlation between total testosterone and leptin level (r=-0.794, p<0.001). No correlation was found between leptin and CIMT (p=0.184).
  
  
  CONCLUSIONS
  Testosterone deficiency in hypogonadal men is associated with vascular parameters of atherosclerosis. The findings may establish indications for testosterone replacement therapy in hypogonadal men.
