Keller JJ, et al. - By using population-based data in Taiwan, researchers estimated the connection between haemorrhoids and erectile dysfunction (ED). This case-control study identified 6,310 individuals with ED as cases and randomly selected 31,550 controls. The authors discovered that the odds ratio (OR) for previous haemorrhoids among cases was 1.90 when compared with controls after adjusting for monthly income, geographical location, hypertension, diabetes, coronary heart disease, hyperlipidemia, obesity and alcohol abuse/alcohol dependence syndrome. When compared with controls, younger cases showed a higher risk for prior haemorrhoids. In particular, when compared with controls, the adjusted OR among cases < 30 years old was 3.71. Overall, the authors concluded that an association was found between ED and a prior diagnosis of haemorrhoids.
