Objective: Previous study conducted by the Turkish Society of Andrology in 1999 reported the prevalence of erectile dysfunction (ED) as 69.2% in men of >= 40 years of age, using a single-item non-validated question. This rate seemed to be higher compared to the studies reported worldwide. So, there was a need to carry out another epidemiological study by using validated questionnaires. Our aim was to investigate ED prevalence, severity, and its correlates in men aged >= 40 years using validated tools.
