The aim of this study was to develop a screening test based on the Leiden Impotence Questionnaire (LIQ) in order to assist in the difficult process of differentiating between psychogenic and organic erectile dysfunction (ED). The main sample consisted of 176 patients with ED, which was classified according to the results of the urological and psychiatric assessment as either organic, in 109 (62%) patients, or psychogenic, in 67 (38%) patients. A logistic regression model including six general items from the LIQ correctly identified psychogenic ED in 62 % of the cases, and organic ED in 86%) with an overall correct classification rate of 76%. Adding information regarding sexual intercourse and the relationship in patients who had a partner and were having sexual intercourse the correct classification rates were: psychogenic 77 %, organic 94%) and overall 87 % Discrimination between psychogenic and organic ED is improved when more information concerning sexual activity can be assessed.

During the last decades, erectile dysfunction was considered a direct consequence of aging and, although of a great concern for the affected patient, little was available to evaluate and treat this problem. If aging could not be invoked in all cases, than the psychogenic etiology was the only explanation. Over the coming years, a better understanding of the physiology involved in the penile process of tumescence and detumescence has allowed for better approach of each disease asociated with erectile dysfunction so that adequate treatment modalities can be applied to the pacient. As we all know, every pacient is a particular case. The development of modern PDE-5 inhibiters, along with other more or less invasive therapies, puts a new light on the medical approach of ED.

The Third International Conference on the Management of Erectile Dysfunction: Linking Pathophysiology and Therapeutic Response, co-chaired by Ajay Nehra and William D. Steers was held July 26 -27, 2002, in McLean, Virginia. The conference was designed for an invited expert clinical faculty who wished to expand their knowledge and contribute new information and perspectives regarding the management of erectile dysfunction (ED). The goals of the conference were to review and discuss implications of pathophysiological differences in disease for different patient groups, discuss new opportunities for using oral therapies for the treatment of ED, review research, preclinical and clinical information related to treatment of specific patient groups, and discuss prevention strategies.

Most men older than 60 years experience some degree of erectile dysfunction (ED). The physiology of erections is complex, with contributions from hormonal, vascular, psychological, neurologic, and cellular components. ED is strongly associated with cardiovascular risk factors, and this fact plays a major role in the prevention and treatment of ED. In this article, we review the evaluation of ED in terms of history, physical examination, and common laboratory studies. Additionally, we review major considerations when prescribing phosphodiesterase type 5 inhibitors and other medical treatments, including intraurethral alprostadil, penile injection therapy, and testosterone replacement. Proc. 2006;81(3):385-390 BPH = benign prostatic hyperplasia; cGMP = cyclic guanosine monophosphate; ED = erectile dysfunction; LH = luteinizing hormone; PDE = phosphodiesterase; PDE-5 = PDE type 5; PSA = prostate-specific antigen
