The intratesticular arteries pursued a coiled course and arborized in the testicular parenchyma. The centripetal arteries converged on the mediastinum and formed clusters of spirally coiled, vessels before turning centrifugally. The testicular parenchyma was drained mainly through the centrifugal veins and partly through the central vein. The concentration of the capsular veins was comparatively more towards the epididymal border than on the free border. These capsular veins pursued a straight course towards the caputal extremity of the testis where they divided and anastomosed many a times to form the pampiniform plexus of veins. The coiling of the intratesticular arteries, theie clustering at the mediastinum testis and the presence of juxtaposed parenchymal veins seem to have some role in the hemodynamic and thermoregulatory mechanism of the buffalo testis.
睾丸内动脉呈盘绕状走行，并在睾丸实质内分支。向心动脉汇聚于纵隔并形成螺旋状盘绕的血管丛，然后转向离心方向。睾丸实质主要通过离心静脉引流，部分通过中央静脉引流。包膜静脉在附睾缘的浓度相对比游离缘更高。这些包膜静脉向睾丸头端呈直线走行，在那里它们多次分支并吻合形成蔓状静脉丛。睾丸内动脉的盘绕、它们在睾丸纵隔处的聚集以及相邻实质静脉的存在似乎在水牛睾丸的血流动力学和体温调节机制中发挥了一定作用。
