5 Preface The first edition of Male Sexual Function: A Guide to Clinical Management was published in Since that time, two new oral medications for erectile dysfunction (ED), Vardenafil (Levitra ) and Tadalafil (Cialis ), have been introduced. Links between ED and lower urinary tract symptoms have been postulated, advances in the basic science of erectile physiology have occurred, and the appreciation of ED as a form of endothelial dysfunction and a harbinger of other more potentially lethal forms of vascular disease has become more widespread. In some instances, third-party payers have reduced or eliminated coverage for ED treatments in an attempt to cut costs. They have classified sexual activity as recreational, lifestyle, or not medically necessary, but have failed to appreciate the negative consequences of ED, such as depression with all of its ramifications. Male Sexual Function: A Guide to Clinical Management, Second Edition is a comprehensive overview of the field of male sexual function and includes a chapter on female sexual dysfunction, an emerging field with a very high incidence in the population and an ever-growing following. The goal is to educate all disciplines in the facts of sexual function and dysfunction in the hope that practitioners will feel comfortable assessing and counseling patients about their sexual needs and concerns and will be able to treat basic problems with easily prescribed therapies and know when and where to refer more complex cases. More money is now spent on advertising ED drugs than any other medical product in the world. Viagra is the second most recognized product in the world after Coke. Patients know that treatments are available and, with more openness in discussing sexual matters, are less hesitant to discuss these with their physician. Polls have shown that an overwhelming majority of patients (96%) believe that ED should be treated and 75% feel that physicians should address this area in a comprehensive evaluation. Hence, it behooves practitioners to become familiar with this area and to keep up to date on the latest developments. Male Sexual Function: A Guide to Clinical Management, Second Edition should accomplish that goal. John J. Mulcahy, MD, PhD v
