Some features of the angioarchitecture of the testis in guinea-pig

Abstract

The branches of the testicular artery in guinea pig were a main capsular artery and some capsular branches with oblique-longitudinal and transverse-longitudinal dispositions, and variable patterns at the lateral and medial surfaces of the testes. Subcapsular branches arose through the proper testicular artery or by the capsular artery and the subcapsular branches emitted: the extralbuginic blood vessels placed between the mesothelium layer and the proper dense albuginea layer of the testis capsule, the intralbuginic vascular vessels characterised by presence of arterial and venous segments inside the myostromal structure of the testis albuginea and the subcapsular and intratesticular sequential vessels which appeared as small arteries and veins, arterioles and venules and capillaries of the capillary trees. The last vessels, mainly the arterioles, venules and capillaries of the testis showed a complex pattern of disposition, in which was viewed parallel and perpendicular vessels concerning to the spatial orientation of the seminiferous tubules.
