RESUMO
PURPOSE: Pathogenically, both erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) are closely related to vascular problems, and vascular problems are closely associated with obesity. This study evaluated the relationships between obesity, BPH, and ED. MATERIALS AND METHODS: The medical history of male patients, aged > or =40 years, evaluated at urology outpatient clinics of 11 university hospitals in Korea with chief complaints of lower urinary tract symptoms (LUTS)/BPH and ED were retrospectively evaluated. The correlations of medical history, body mass index (BMI), international prostate symptom score (IPSS), prostate volume, International Index of Erectile Function -5 (IIEF-5), and serum testosterone level were assessed. RESULTS: Body mass index showed significant correlations with IPSS (r=0.087, p=0.003), prostate volume (r=0.384, p<0.001), IIEF (r=-0.072, p=0.015), and serum testosterone concentration (r=-0.303, p<0.001). CONCLUSIONS: Body mass index correlates with testosterone concentration, prostate volume, and markers of LUTS and ED in men with the latter conditions.
