Broke7i Penis. InfIam?natio?i of the Penis 147 



from our observation before we had an opportunity to fully 

 investigate. 



6. "Broken Penis." When the penis becomes violently 

 and abruptly bent while erected, the tissues at the point of cur- 

 vature become severely injured, inflammation and swelling occur, 

 the erectile ti.ssues become infiltrated and undergo sclerosis. 

 After a tardy recovery, distortion remains ; the penis is bent or 

 curved. In addition to the deformity, there is sometimes an in- 

 terruption of the vascular or nerve supply to the portion of the 

 penis distal to the seat of the injury and, in this part, erection 

 may be wholly wanting, while normal in the proximal portion of 

 the organ. The deformity and want of erection in the distal 

 portion serves to prevent copulation. 



Treatment is usually impracticable. The defects cannot, as 

 a rule, be remedied and generally occur too high to permit of 

 successful amputation from a breeding standpoint. In some 

 cases of broken or curved penis, where copulation was still pos- 

 sible, sterility is claimed to have resulted because the semen 

 ejaculated from the bent organ was thrown laterally against the 

 side of the vagina instead of forwards against the os uteri and 

 the spermatozoa failed to enter. The difficulty in such ca.ses 

 was apparently overcome by artificial insemination, the semen 

 being collected from the posterior portions of the vagina and 

 introduced into the os uteri. 



7. Inflammation of the Penis may arise in a variety of 

 ways. We have already referred to the Venereal Infections 

 which generally lead to more or less inflammatory disease of this 

 organ. 



In addition, inflammation occasionally results from physical 

 injuries during coition, from kicks in stallions, from lacerations 

 when breaking from enclosures while the penis is erected, from 

 the tail hairs of the mare becoming caught by the penis and 

 cutting it, by the " hanging fast " of the dog during copulation 

 and in many other ways. 



The effects of inflammation of the penis upon copulatory 

 powers varies greatly. Some males, like the bull, affected with 

 one of the venereal diseases, may copulate in spite of the fact 

 that the process causes profuse hemorrhage from the penis, which 

 must be accompanied by pain. The stallion with bursattee of 

 the urethra proceeds to copulate regularly, although he bleeds
