A precise determination of the cause of any individual case of ED is often difficult and may be impossible because ED is often due to multiple factors. This is a consequence of the complicated nature of the human sexual response and the complex physiology of penile erection and relaxation. Normal erectile function requires the coordination of vascular, neurologic, hormonal and psychological factors and any condition that interferes with one or more of these processes may result in ED.
Attitudes concerning age and psychological factors, commonly associated with ED in the past, have changed in the last two decades. Although the prevalence of ED increases with advancing age, ED is no longer regarded as an inevitable consequence of aging. Whereas most cases of ED were once considered primarily psychological and/or psychiatric in origin, it is now well-recognized that organic, non-psychological causes of ED play a much more significant role in the development of ED. Most researchers agree that pure psychological (emotional) mechanisms are causative in 15% to 20% of cases with organic causes responsible for at least 80% of ED cases. In a number of cases, the situation is "mixed," with significant secondary psychological and social components such as guilt, depression, anxiety, tension or marital discord being present in addition to one or more underlying organic components.
