CHAPTER VII. 

 MALE GENITAL ORGANS. 



The scrotum, the vaginal sheath, the testicles, the vas deferens, 

 the vesiculse seminales, the prostate, and Cowper's glands may all 

 become the seat of disease. 



The scrotum and testicles seldom reveal more than mechanical 

 injuries of external origin, producing wounds and cuts and, in the 

 case of severe contusions, hsematoma of the scrotum, of the vaginal 

 sheath, and of the testicles. Inflammation of the testicle, that is to 

 say, traumatic orchitis, is rare ; on the other hand, Moussu has several 

 times seen tuberculous orchitis, for which he has operated. This, 

 however, was in the boar. These different lesions, the last named 

 excepted, usually heal with rest and the application of antiseptic 

 dressings, anodyne and resolvent lotions. 



Breeders seldom retain more entire animals than are strictly neces- 

 sary for reproduction. The others are castrated, and this alone 

 explains why the treatment of genital diseases in male animals of 

 any species is rare. 



TUMOURS OF THE TESTICLE. 



Of the genital diseases which possess real clinical interest the 

 most important are tumours of the testicle. These occur not only in 

 male animals, but also in those which have undergone the operation 

 of bistournage. 



It might a priori be believed that in an animal of the latter class 

 the testicle had been completely destroyed, not only from the physical, 

 but from the pathological point of view. This, however, is by no means 

 the case, and Cruzel has described, under the erroneous designation 

 of sarcocele, tumours of the testicle which develop in oxen of various 

 ages. 



Moussu has had a similar experience with animals of from four 

 to six years of age which had been carefully operated on. 



These tumours, the origin of which is unknown, develop at the 

 expense of the rudiments of the atrophied te&ticle. They vary in
