Topographic and morphometric comparison study of the terminal part of human and bovine testicular arteries
2009
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.
