bulls may sustain traumatic injuries to trie prepuce during breeding wmch include rupture of the epithelium and exposure of the underlying peripenile elastic tissues. These wounds are contaminated at the time of injury and frequently lead to hemorrhage, inflammation, edema and perhaps infection of the infected tissues. These injuries, commonly called preputial lacerations, typically happen during coitus where intromission may force the prepuce caudally toward the sheath and the surface of the prepucebursts during the rapid forceful ejaculatory lunge. The laceration or bursting wound most commonly occurs longitudinal to the long axis of the ventral surface of prepuce and edema quickly develops in the traumatized skin and elastic tissues. Bulls of the Bos Taurus breeds most often retract the penis back into the preputial cavity where subsequent swelling of the affected tissues prevent further penile extension with resultant phimosis. Bulls of Bos indicus breeds have a longer sheath and prepuce and frequently prolapse the damaged tissues. The injured bull may continue to attempt breeding resulting in additional damage in the already traumatized tissues. In breeds that do not tend to prolapse the damaged prepuce, diffuse cellulitis or abscessation are more likely to occur than in those breeds that typically prolapse the injured prepuce. The extent of the injury varies greatly and determines the prognosis and therapeutic effort needed to return the bull to breeding soundness.
