          In studies on the vascularization of the testes in boars 112 testes were used. The topographic-anatomical conditions of the arteries were studied by means of roentgenography, stereo-roentgenography, the corrosive method and by gel and Indian ink injection. The arising of the aa, testiculares from the abdominal aorta and the length of the convolution of the testicular artery varies in the boar. The rr. epididymales arise partly from the rectal part of the testicular artery, partly from the convolution. Most frequently the arising from the upper third of the convolution was observed. A case has been stated with high release of the Rr. epididymales. The loops of the latter envelope the entire convolution of the testicular artery. Division of the marginal part of the testicular artery occurs in most cases at the transition of the margo epididymis into the margo liver. The 2 rr. testiculares formed by the division of the marginal part of the testicular artery are not always of the same thickness. Only 1 of them reaches the frontal part of the testis. In the boar anastomoses are formed between the testicular and the epididymal branches. The authors failed to prove th accessory artery of the testis in the material. In the boar, the course and ramification of the centripetal and centrifugal arteries coincides with that in the ram. An independent branch of the epididymal artery was observed, forming an independent a radiate centripetalis. In the boar, the artery of the seminiferous duct anastomoses with the branches from the caudal epididymal branch and with the cremasteric artery.
