Penile Arterial Waveform Analyzing System for Early Identification of Young Adults with High Risk of Erectile Dysfunction

High prevalence of erectile dysfunction in young adults has raised much concern regarding early identification of risk factors for timely intervention. This study aimed at identifying young males at risk through a novel penile arterial waveform analyzing system. Between July 2009 and December 2010,...

Description
Summary:High prevalence of erectile dysfunction in young adults has raised much concern regarding early identification of risk factors for timely intervention. This study aimed at identifying young males at risk through a novel penile arterial waveform analyzing system. Between July 2009 and December 2010, 30 young adult volunteers of age 18 to 29 without known history of vascular diseases or erectile dysfunction were recruited. Basic demographic and anthropometric characteristics (i.e., age, body weight, body height, body mass index, waist circumference) were recorded. Blood samples were obtained for determining levels of testosterone, glycosylated hemoglobin, triglyceride, fasting sugar, low‐ and high‐density lipoproteins (HDL). Data obtained from visual sexual stimulation (VSS) RigiScan and the penile arterial waveform amplitude (PAWA) ratios were compared in terms of their correlations with anthropometric and serum biochemical parameters using Pearson's correlation analysis. PAWA ratios were found to correlate with Rigidity (tip and base) (r = 0.425, P = 0.019 and r = 0.664, P
