Erectile disorder: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Statistics indicate an organic basis for erectile dysfunction in 20% to 50% of men who have this disorder. In some patients, psychogenic and organic factors coexist, making isolation of the primary cause difficult.

Psychogenic causes may be intrapersonal, reflecting personal sexual anxieties, or interpersonal, reflecting a disturbed sexual relationship. Intrapersonal factors generally involve guilt, fear, depression, or feelings of inadequacy resulting from previous traumatic sexual experience, rejection by parents or peers, exaggerated religious orthodoxy, abnormal mother-son intimacy, or homosexual experiences. Interpersonal factors may stem from differences in sexual preferences between partners, lack of communication, insufficient knowledge of sexual function, or nonsexual personal conflicts. Situational impotence, a temporary condition, may develop in response to stress, as in performance anxiety.

Organic causes may include chronic diseases, such as cardiopulmonary disease, diabetes, multiple sclerosis, or renal failure; spinal cord trauma; complications of surgery; drug- or alcohol-induced dysfunction; and, rarely, genital anomalies or central nervous system defects.

Erection problems are common in adult men, with almost all men experiencing occasional difficulty getting or maintaining an erection.

About prevalence and incidence statistics:

The term 'prevalence' of Impotence usually refers to the estimated population of people who are managing Impotence at any given time. The term 'incidence' of Impotence refers to the annual diagnosis rate, or the number of new cases of Impotence diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
