The aim of this study was determined that arterial vascularization of testicles, epididymis and ductus de-fereces in Chinchilla. Five adult male chinchilla (Chinchilla lanigera) varied between 550 g and 600 g live body weight obtained from Afyon Kocatepe University Experimental Animal Unit were used in the study. Blood was removed (rom arteria carotis communis and coloured latex was injected. The right arteria testicularis originated from the caudo-lateral aspects of the arteria renalis in 2 cadavers whereas it was from the arteria abdominalis approximately 2 mm alter the arteria renalis. The lelt arteria testicularis left from aorta abdominalis alter, approximately 4 mm from the arteria renalis sinister. It was observed that the arteria testicularis gave branches to testicles, caput and corpus epididymidis, and also a few thin branches to the cauda epididymidis. Arterial vascularization of cauda epididymidis and ductus deferences was supplied by the arteria ductus deferences that was originated from the arteria iliaca externa.
