The aim of the study was to analyze topography and morphometry of the arteries supplying bulls’ gonads. 30 gonads were used in the study. Corrosive casts of extratesticular arteries were analyzed macroscopically and with stereoscopic binoculars. In our research the testicular artery was the major vessel supplying the bovine masculine gonad. The minor vessels included the deferens duct artery and cremasteric artery. There was no direct connection between those three arteries; however, indirect connections were always present. The anastomoses were formed by a well-developed deferens duct branch of the testicular artery, the deferens duct and cremasteric arteries. This artero-arterial anstomosis had a horseshoe or U-like shape and was located in an area of the tail of the epididymis. The analysis of the diameters of the arteries of the casts showed that in the instance of an occlusion of the testicular artery, collateral circulation formed by the deferens duct artery and the cremasteric artery may be insufficient for the proper blood supply of this organ.
