Erectile dysfunction: an underdiagnosed condition associated with multiple risk factors

Abstract

Erectile dysfunction (ED) is a common condition with a significant effect on the quality of life. The prevalence of ED rises with increasing age and other conditions (hypertension, diabetes, ischaemic heart disease, hypercholesterolaemia and depression). The MALES study is one of the largest epidemiological surveys to investigate the prevalence of ED. This study included 27839 patients spanning eight countries. In addition to the MALES study, we review the emerging link between lower urinary tract symptoms (LUTS), benign prostatic hypertrophy (BPH) and ED, including the effect of BPH treatment on sexual function. Preliminary data from the MALES II study shows a significant cascade effect in the treatment seeking behaviour and treatment adherence of patients taking sildenafil for ED. We explore the possible reasons behind the discontinuation of oral phosphodiesterase inhibitors prescribed for the long-term treatment of ED.
