Psychological causes were once widely assumed to be the predominant cause of erectile dysfunction. However, if the correct definition of erectile dysfunction is applied, namely, the persistent loss of penile rigidity in all ircumstances, then psychogenic erectile dysfunction proves to be less common thanits organic counterpart, especially in older men. Psychogenic erectile dysfunction typically occurs in younger men, and is variable and often associated withperformance anxiety. Increased sympathetic vasoconstrictor tone and raised circulating norepinephrine levels are most probably involved. Psychogenic factors also come into play in other forms of erectile dysfunction, as failure oferection itself induces anxiety, loss of confidence and sometimes relationship difficulties. The conviction that an erection will not develop when required, therefore, becomes a self-fulfilling prophesy. Read more: Treatment options for erectile dysfunction.
One problem for epidemiologists trying to quantify the extent and impact of erectile dysfunction is the frequent unwillingness of men to discuss the problem frankly. The accuracy of almost all data inthis disease area istherefore impaired by the reluctance of many, particularly older, men to respond towhat they regard as overly personal questions. However, with the development of simple questionnaires which can be self-administered, and the gradual breakdown of social taboos surrounding the open discussion of sexual issues, it is possible to anticipate higher-quality information in the future.

Reactive or endogenous depression is strongly associated with erectile dysfunction: nearly 90% of severely depressed men report complete impotence. Treatment with antidepressants may sometimes improve the situation, although both monoamine oxidase inhibitors and tricyclic antidepressants may in themselves cause erectile dysfunction.Selective serotonin reuptake inhibitors, such as mirtazapine may not only cause erectile dysfunction, but may also retard ejaculation.
