Age-related vascular damage contributes to benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) in aging men. Reduced blood flow in the prostate and penis correlates with worse symptoms and disease severity.

Area of Science:

  • Urology
  • Andrology
  • Gerontology

Background:

  • Benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) are common in aging men, often co-occurring.
  • Urogenital aging is associated with vascular changes impacting lower urinary tract and erectile function.

Purpose of the Study:

  • To investigate the association between BPH, ED, and vascular health in aging men.
  • To compare vascularity and symptom scores in men with BPH and ED against healthy controls.

Main Methods:

  • Cross-sectional study using contrast-enhanced colour Doppler ultrasonography (CDUS) to assess prostate and penile vascularity.
  • Quantitative measurement of colour pixel intensity (CPI) and resistive index for objective perfusion evaluation.
  • International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) for symptom quantification.

Main Results:

  • Reduced prostate transition zone perfusion and increased resistive index observed in men with BPH compared to controls.
  • Men with BPH and ED exhibited significantly worse IPSS and IIEF scores.
  • Concomitant vascular damage, such as in diabetes mellitus type 2 and atherosclerosis, further worsened perfusion and symptom scores.

Conclusions:

  • Age-related vascular impairment is a significant factor in the pathogenesis of BPH and ED.
  • Chronic ischemia due to vascular damage likely contributes to the development and severity of these conditions.
