The first edition of Male Sexual Function: A Guide to Clinical Management was published in 2001. 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 comp- hensive 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.
