[Topographico-anatomic data on the testicular artery, ductus deferens artery and cremaster artery in the stallion].
Abstract: To study the vascularization of the testis of stallions we used 96 testes. We examined its topography and anatomy by roentgenography, stereoroentgenography, by the corosive method, and by means of gel and China ink injections. To make the roentgeno-arteriograms we used minimum emulsified in glycerine as contrast medium. The branching off of the Aa. testiculares from the Aorta abdominalis is variable in stallions. We observed also a peculiar age-dependent arrangement of the loops of the convolution. In the adult stallion, the shape of the convolution is either cylindrical or conical, spindle-shaped, or irregular. Bifurcation of the A. testicularis before entering the testis did not occur. The epididymical arteries arise either from the convolution or from the Pars recta a. testicularis. They may ramify from a common branch near the origine of A. testicularis. We found regular, direct anastomoses between A. epididymidis cranialis and the branches from the Rr. testiculares. Pars marginalis a. testicularis bifurcates at the transition plane of Margo epididymidis and Margo liber, eventually in the middle 1/3 of Margo epididymidis. Rr. testiculares run parallelly along the Margo liber and give off a number of verically arising branches. The Aa. radiatae centripetales run to the Mediastinum testis without giving off branches. We have not found any anstomoses between the centripetal arteries or the centripetal and centrifugal ones. The A. ductus deferentis is just as thick as the branches from the A. epididymidis caudalis. The lumina of the A. cremasterica is 0.5 to 1 mm. We did not succeed in filling it up reversely through the A. epididymidis caudalis. The artery anastomoses with A. ductus deferentis and A. epididymidis caudalis.

The researchers in this article have conducted an in-depth anatomical and topographic study of the blood supply to the stallion’s testes. Using a variety of imaging techniques and 96 testes, they provide a detailed account of the intricacies of the testicular blood vessels, their branching and their relationship with various structures of the testis.
Methods
- The study was performed on 96 testes from different stallions. This large sample size allows for a more generalized interpretation of the findings.
- Different imaging techniques were used such as roentgenography, stereoroentgenography, corosive method and gel and China ink injections. This provided comprehensive visualization of the testicular arteries.
Findings
- The study reports variable branching of the testicular arteries from the abdominal aorta in stallions. This suggests individual differences in the physical structure of the vascular system of the testes.
- The researchers observed an age-dependent shape of convolution or twisted form of the blood vessels. In adult stallions, the convolution is reported as cylindrical or conical, spindle-shaped or irregularly shaped.
- There was no bifurcation of the testicular artery observed before it enters the testes indicating a direct blood supply.
- The epididymal arteries, supplying the blood to the epididymis, arose from the convoluted testicular arteries or the straight part of the testicular artery. Occasionally these arteries could have a common origin near the testicular artery.
- Anastomoses or connections between the cranial epididymal arteries and the branches from testicular arteries were consistent, indicating a strong interconnected vascular network.
- The testicular artery branches at the transition between the epididymal margin and the free margin, usually in the middle third part of the epididymal margin.
- The presence of centripetal radiating arteries running towards the mediastinum of the testes was noted, without giving off any branches. Additionally, no anastomoses were observed between these arteries or between the centripetal and centrifugal ones.
- The artery of the ductus deferens was as thick as the branches from the caudal epididymal artery. They did not manage to reverse fill the cremasteric artery through the caudal epididymal artery. This artery also showed anastomoses with the ductus deferens artery and the caudal epididymal artery.
Significance
- The findings of the study contribute to the understanding of the unique features of the vascular system of the stallion’s testicle.
- They also provide valuable insights into the anatomy and topography of the testicular, cremasteric and ductus deferens arteries, which can be invaluable for surgical interventions and diagnostic procedures in the equine reproduction medicine.
