It is important to distinguish the condition from other sexual dysfunctions, such as premature ejaculation and loss of libido. Several formalized sexual questionnaires, such as the IIEF (Internation Index of Erectile Function) and EDITS (Erectile Dysfunction Inventory of Treatment Satisfaction), allow one to detect the presence and grade the severity of erectile dysfunction. The complete IIEF is composed of 15 questions; an abridged 5-item version, called the sexual health inventory for men (SHIM), has been developed and validated.29 Allowing a patient to complete such a questionnaire before his first clinical encounter may produce a more comfortable clinical environment.30 The duration of the problem, time of onset and degree of patient and partner concern should also be elucidated. The circumstances surrounding erectile dysfunction may be helpful in determining whether a situational or nonorganic factor is involved. Sudden onset, maintenance of nocturnal erections, presence of psychological problems and concurrent major life events or relationship issues may be associated with nonorganic erectile dysfunction.31 Concurrent medical illnesses and any medications the patient may be taking should be reviewed.
