title: Metabolic syndrome and erectile dysfunction among obese non-diabetic subjects.
abstract: OBJECTIVE
  To investigate whether MS is associated with erectile dysfunction (ED) among obese non diabetic individuals.
  
  
  METHODS
  A cross-sectional study was carried out to examine the association between the cluster of abnormalities related to the MS and ED as evaluated by the International Index of Erectile Function (IIEF). Fifty consecutive obese [i.e. body mass index (BMI) > or =30 kg/m2], nondiabetic whites (age 42.1+/-11.3 yr, BMI 43.3+/-8.7 kg/m2) were recruited.
  
  
  RESULTS
  The prevalence of MS as well as that of any MS component were not different between subjects with or without ED. Neither the prevalence of ED (34.3% vs 33.4%, p=0.6), nor IIEF score (21.5+/-3.9 vs 21.7+/-3.7, p=0.8), were different between patients with or without MS. IIEF was similar across subgroups of individuals stratified according to the number of MS components and was not related to HOMAIR index. Hypogonadism was observed in 30.8% and 28.1% individuals with and without MS (p=0.58). Testosterone and BMI levels were inversely related (r=-0.3, p=0.04).
  
  
  CONCLUSIONS
  Among obese non-diabetic individuals the risk of developing ED is independent of the presence of MS factors. Testosterone levels progressively decrease with increasing body weight.
