The course of the testicular artery and the number and distribution of its penetrating branches were studied in 30 pairs of testicles of adults Pega donkeys originated from several regions of Minas Gerais (Brazil), in analysing the squematic draws from models obtenied by corrosion after vinyl acetate injection. In these animals it was noted that this artery shows four differents vascular arrangements according its division and the predominance in the organ blood supply showed by one or other of the resulting branches. The distribution of the penetrating branches per quadrant in median values, is made so that in the right testicles the most vascularized is the craniomedial (17,0), followed by the caudomedial and the craniolateral (15,5) and the caudolateral (15,0). In the left testicle, the caudolateral quadrant showed the highest number of penetrating branches (18,5), followed by the craniolateral (17,0),craniomedial (16,0) and the caudomedial (14,0). Anastomosis between the testicular artery and its branches or between different collaterals which were originated from that artery were observed in 15.0% of the cases. The total number of penetrating branches in median values was respectively 66.5 and 66.0 to the right and to the left testicle. There were not significant statistical differences between the right testicle and the left one, when the numbers of penetrating branches were compareted.
