PASSIPIERI, Milton; BORELLI, Vicente  and  MIGLINO, Maria Angélica. Contribution to the study of the arterial vascularization of the testicle in buffalo. Braz. J. Vet. Res. Anim. Sci. [online]. 1998, vol.35, n.1, pp.00-00. ISSN 1413-9596.

We studied the vascular pattern of arterial blood supply and the number and distribution of penetrating vessels in 30 pairs of testicles of Murrah buffalos, from 8 months to 5 years old, native from Ilha Solteira (São Paulo-Brazil). The vascular pattern was analyzed in plastic models, obtained by injection of vinilyte in the testicular artery and further corrosion of the organ in 30% sulfuric acid. In these animals the testicular artery showed five vascular arrangements. In one case the artery was divided in two branches, named cranial and caudal in 68.4% which showed: a) equivalent participation of both branches in the arterial vascularization in 35.0%; b) the cranial branch was predominant in 21.7%; and finally the predominant branch was the caudal one in 11.7%. In other studied cases, the testicular artery originated three branches: the cranial, the medial and the caudal ones in 20.0% or that artery originated a varied number of cranial (4-7) and caudal (3-5) branches in 11.6%.
