Summary

Lower urinary tract symptoms (LUTS) are an independent risk factor for erectile dysfunction (ED), not solely confounded by age. Addressing LUTS may improve ED outcomes in men.

Area of Science:

  • Urology
  • Men's Health
  • Andrology

Background:

  • Lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) are common conditions in aging men.
  • The relationship between LUTS and ED is complex and may be influenced by confounding factors such as age.

Purpose of the Study:

  • To determine if LUTS are an independent risk factor for ED.
  • To assess whether age confounds the association between LUTS and ED.

Main Methods:

  • A cross-sectional study of 2858 men aged 20-80 years in Vienna.
  • Participants completed the International Prostate Symptom Score (IPSS) and International Index of Erectile Function-5 (IIEF-5).
  • Health evaluations included physical exams, lifestyle assessments, and laboratory studies.

Main Results:

  • LUTS and ED prevalence increased significantly with age (P <0.0001).
  • Multivariate analysis revealed IPSS (P = 0.0001), obstructive LUTS (P = 0.0001), nocturia (P = 0.04), and LUTS bother score (P = 0.002) were significantly associated with ED.
  • LUTS (OR 2.2), voiding symptoms (OR 2.0), nocturia (OR 1.4), and LUTS bother (OR 2.5) were independent predictors of ED.

Conclusions:

  • LUTS, particularly voiding symptoms, nocturia, and quality-of-life impairment, are independent risk factors for ED.
  • These findings suggest LUTS management may be crucial for treating ED in men.
  • Further research into the LUTS-ED connection is warranted.
