The aim of the study was to compare the terminal parts of testicular artery topography in human and bovine gonads. The study was made on two extremely different types of location of the mediastinum testis. The investigation was carried out on 80 (40 human and 40 bovine) corrosive casts of the testicular arteries. The differences between the species, including the different course of the testicular artery inside the spermatic cord and in the posterior margin of the gonads, were observed. The division of the testicular artery into terminal branches was located in men on the level of the mediastinum testis, and in bulls close to the inferior end of the gonad. The types of terminal division were similar in both groups. In men, the testicular artery course inside the spermatic cord was more variable than in bulls. The artery was straighter, and in 75% of the cases it did not form the loops which were present in 100% of the bovine specimens. The bovine testicular artery in the posterior margin of the testis was longer and had a more variable course than in men.
该研究的目的是比较人类和牛性腺中睾丸动脉地形的终末部分。该研究针对睾丸纵隔两种截然不同的位置类型展开。对80个（40个人类和40个牛类）睾丸动脉腐蚀铸型进行了研究。观察到了物种之间的差异，包括精索内和性腺后缘睾丸动脉的不同走行。睾丸动脉分为终末分支的位置，在人类位于睾丸纵隔水平，而在公牛则靠近性腺下端。两组的终末分支类型相似。在人类中，精索内睾丸动脉的走行比公牛更具变异性。该动脉更直，在75%的病例中不形成环，而在100%的牛标本中存在环。睾丸后缘的牛睾丸动脉比人类的更长，走行更具变异性。
