Characterisation, prevalence, and consultation rates of erectile dysfunction

Erectile dysfunction (ED), assessed clinically by tools such as the International Index of Erectile Function (IIEF), affects millions of men across the world. Around 10-25% of men of all ages are affected rising to 20-45% in older age groups. Different definitions of ED and selection of different patient populations account for much of the variability reported in epidemiological surveys. Ageing populations in the developed world and growing populations in the developing world make it likely that the prevalence of ED will increase in the future. ED affects quality of life, and the condition may result in outcomes such as anxiety and withdrawal from a relationship. The condition remains a source of embarrassment for many men and health professionals, and it remains under-reported, under-recognized, and undertreated. Adequate medical assessment and intervention are needed to address ED.
