Abstract
Erectile Dysfunction (ED) has been defined as a persistent inability to attain or maintain erection adequate to permit satisfactory sexual function (National Institute of Health 1993). It is estimated that a third of men will be affected by ED at some point during their lives (Heidelbaugh 2010). Whilst published figures provide an indication of the prevalence of ED, they are likely to underestimate the true number as many men will not seek help either due to embarrassment or through acceptance that ED is inevitable with advancing age (Hatzimouratidis et al. 2010).
The pathophysiology of ED may be neurogenic, hormonal, vasculogenic, drug-induced, anatomical, and/or psychogenic. However, regardless of the pathological basis for ED, the condition can have a profoundly negative psychological impact on relationships, quality of life and overall affect self-esteem (Gruenwald 2012). Therefore, to establish an effective ED management plan in a timely fashion is of paramount importance for the well-being of the sufferer and partner.
By the end of this chapter we hope that you will have a better understanding of the pathophysiology and management of ED.
