Diagnosis and investigation of men with erectile dysfunction

Given that most men who present with erectile dysfunction (ED) are likely to be treated with oral therapy in the first instance, their diagnosis and investigation should reflect this. The objectives of this assessment should focus on identification of important risk factors for ED, such as diabetes, hypertension and hyperlipidaemia and on those (few) men who have curable ED. As such there are a number of baseline tests that should be done in all patients, with specialised investigations restricted to a few men.
