ABSTRACT
INTRODUCTION Erectile dysfunction (ED) has been defined as the consistent or recurrent inability of a man to attain and/or maintain a penile erection sufficient for satisfying sexual performance. Consistency is an important aspect of the definition of ED. Erectile difficulties must be reported to occur on a consistent or recurrent basis in order to qualify for the diagnosis of ED. A three-month minimum duration is generally accepted for establishment of the diagnosis. In some instances of trauma or surgically induced ED (e.g., postprostatovesiculectomy or postcystectomy), the diagnosis may be confirmed prior to three months. Although ED is a benign disorder, it is closely related to physical and psychosocial health, and has an essential influence on the quality of life of both patients and their partners. Clinically, the diagnosis of ED is primarily based on patient’s self-report. The diagnosis may be supported by objective testing (or partner’s report), nevertheless these measures cannot displace the patient’s self-report in classifying the disorder. The necessary reliance on patient’s reports implies that cultural factors and patient-physician communication and relation will be important determinants in defining and diagnosing the disorder.
