Scrotal trauma accounts for less than 1% of all trauma-related injuries, because of the anatomic location and mobility of the scrotum (Cass and Luxenberg 1991). The peak occurrence of scrotal trauma is in the age range of 10–30 years (Wessells and Long 2006). Typically it results from direct injury due to sport injury, motor vehicle collision, or altercation (Deurdulian et al. 2007). Penetrating trauma is also possible, due to gunshot wounds, animal attacks, and self-mutilation. Postsurgical and thermal injuries are rare, but iatrogenic injuries resulting from complications of inguinal herniorrhaphy are quite common. The right testis is injured more often than the left one because of its greater propensity to be trapped against the pubis or inner thigh.
