Compared with non-smokers, the adjusted odds ratios for erectile dysfunction were 1.24 (95% confidence interval (CI) 1.01 to 1.52, p ?=? 0.04) for those smoking ? 20 cigarettes per day and 1.39 (95% CI 1.05 to 1.83, p ?=? 0.02) for those smoking > 20 cigarettes per day, after adjusting for other confounding factors. Older age, low level of education, and taking medications for cardiovascular disease were also independently and positively associated with erectile dysfunction.
