The National Institute of Health defined 'erectile dysfunction' as the persistent inability to achieve and/or to maintain an erection for a satisfactory sexual performance. In last few years, the concept of erectile dysfunction has evolved from that of a disorder referred to as 'impotence' which used to be considered predominantly psychogenic to that of 'Erectile Dysfunction' (ED), a well understood physiologic result of multiple risk factors, both psychological and organic. The most common cause of organic erectile dysfunction is vasculogenic causes. Doppler evaluation of cavernosal arteries after intracavernosal injection of Papaverine is particularly useful in the evaluation of vasculogenic causes.
