*INFLAMMATORY (Orchitis)
Orchitis is inflammation of the testes. One or both testes may be affected.

Aetiology:
#Release of sperm into interstitial tissue - granulomatous response.
#Infections. May arise by three routes:
#*Haematogenous bacterial/viral infection.
#*Secondary infection following localised trauma.
#*Retrograde infection from accessory glands and/or epididymis.

Various organisms involved classically, Brucella spp.
''Brucella abortus, A. pyogenes, M. tuberculosis'' in cattle
<Br>''B. canis'' in imported dogs
<Br>''B. suis'' in pigs

The epididymis and seminal vesicles may also be affected in animal species with well developed accessory glands - i.e. bull and boar.

Histologically:Range of severity depending on the extent of vascular occlusion and/or pathogenic organism.
:Early stages:necrosis of seminiferous epithelium and desquamation ± haemorrhagic or fibrinopurulent exudate if there is bacterial infection.
:Chronic:fibrosis ± calcification.

Granulomata are often a feature of severe orchitis due to Brucella spp. infection.
