  • Title: Arterial supply of human and bovine testes: a topographic and morphometric comparison study.
    Author: Polguj M, Jędrzejewski KS, Topol M.
    Journal: Folia Morphol (Warsz); 2010 Nov; 69(4):225-31. PubMed ID: 21120809.
    Abstract:
    The aim of the study was to compare the arteries supplying human and bovine masculine gonads. The study was made on two extremely different types of location of the mediastinum testis. The study was made on 100 (50 human and 50 bovine) corrosive casts of the testicular, cremasteric, and deference duct arteries. The differences between the species included different courses of the testicular artery inside the spermatic duct, the relative size of the three arterial diameters, and the morphology of the anastomoses of the arteries. In human testicular arteries, the course inside the spermatic course was more variable than in that of bulls. The artery was straighter and in 80% of the cases did not form the loops which were present in 100% of the bovine specimens. The bovine testicular artery was significantly wider in relation to the cremasteric and deferens duct arteries than the human one. This finding suggests that collateral blood flow to the testis was less effective in bulls than in men. The human testicular artery directly connected the other two with its terminal branches. The bovine testicular artery connected with the cremasteric and deferens duct arteries indirectly by means of its deferens duct branch.
