Abstract
Premature ejaculation (PE) is defined as the ejaculation that always or nearly always occurs prior to or within about 1 min of vaginal penetration with inability to delay ejaculation on all, or nearly all, vaginal penetrations followed by negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy (Serefoglu & Saitz, 2012). It is the most common male sexual disorder and usually ranges between 20 and 38% of the male population which is affected by PE at any one time. It is known to affect adult males in all age groups at similar rates (Hatzimouratidis et al., 2010, McCarty & Dinsmore, 2010, Linton & Wylie, 2010).PE has been classified into two types; primary and secondary with different etiological theories and prognosis (Schapiro, 1943). The primary (lifelong) type is characterized by experiencing PE from the first sexual act encountered during puberty or adolescence (Waldinger, 2005). The secondary (acquired) PE is defined when the patient had successful coital relationships in the past, yet began experiencing PE (Waldinger, 2008). There are psychological and biological theories tried to explain the etiology of primary PE (McMahon, 2007). On the other hand, many factors may contribute in the occurrence of secondary PE as prostatitis and urethritis, erectile dysfunction, cardiovascular, endocrinal, neurological diseases and iatrogenic (Baum & Spieler, 2001).
