title: Prevalence and Severity of Erectile Dysfunction as Assessed by IIEF-5 in North Indian Type 2 Diabetic Males and Its Correlation with Variables.
abstract: BACKGROUND
  The aim of this study was to assess the severity of the erectile (ED) dysfunction among type 2 diabetic men. For subjective information patients were asked to fill up the IIEF questionnaire. This study was also done to correlate ED with other variables like age, obesity, duration of diabetes, degree of diabetic control and complications of diabetes. Neuropathy was assessed objectively by using the Vibration Perception Threshold (VPT).
  
  
  METHODS
  This study was conducted on 348 patients. Age range of these subjects was 25 years to 75 years. All patients underwent routine clinical examinations which included recording of duration of diabetes, type of diabetes, Body Mass Index, previous HbA1c tests and VPT measurement.
  
  
  CONCLUSIONS
  In the present study, it was observed that there was a significant association of ED with age, duration of diabetes, glycemic control and BMI. In fact, VPT emerged as a strong predictor of ED. We conclude that adding objectivity of VPT measurement improves the subjective predictive value of IIEF-5.
