Topography of the blood vessels of bovine testis
The study focused on both arterial and venous vessels of bovine testis, including the testicular artery, intratesticular arteries and veins as well as pampiniform plexus. The study involved 64 bovine testes. In 27 testes only arterial, in 22 only venous and in 15 both arterial and venous vessels were studied by corrosive method. The results of the study confirmed the majority of previous observations. The most significant novelty was the observation of variable branches of the testicular artery. The vessel originates on the posterior margin of the gonad. The most common termination of the testicular artery was a division into 2 branches of similar diameter (60%). The arterial network of the mediastinum testis was formed by vascular conglomerates in which centripetal arteries become centrifugal ones. Intratesticular arteries are winding with some short straight parts, whereas intratesticular veins are straight all along their length. The blood vessel topography of the bovine spermatic cord is very similar to that described in other mammals. On the basis of the study, the middle part of the posterior margin of bovine testis is recommended for blind biopsy of the gonad. The choice of this area reduces the risk of damage to major vessels.
