Contribution to the study of the arterial vascularization of the testicle in buffalo

Abstract

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%.
