Haemorrhoids are associated with regional vascular abnormalities and rectal
pain, which are hypothesized to increase the risk of erectile dysfunction (ED);
however, few studies have investigated the association between ED and haemorrhoids.
This case-control study aimed to estimate the association between
haemorrhoids and ED by using a population-based data in Taiwan. We identified
6 310 patients with ED as cases and randomly selected 31 550 controls.
Conditional logistic regression was performed to compute the odds ratio (OR)
for having been previously diagnosed with haemorrhoids between cases and
controls. The results show that haemorrhoids were found to be present among
1 572 (24.9%) cases and 4 491 (14.20%) controls. The OR for prior haemorrhoids
among cases was 1.90 (95% CI = 1.78–2.03) when compared with controls
after adjusting for monthly income, geographical location, hypertension,
diabetes, coronary heart disease, hyperlipidemia, obesity and alcohol
abuse ⁄ alcohol dependence syndrome. Younger cases demonstrated a higher risk
for prior haemorrhoids when compared with controls. In particular, the
adjusted OR among cases
