Abstract:
In this study, the architecture of the interstitial tissue of the boar testis was examined by using scanning and transmission electron microscopes. The boar testis was remarkable for the abundance of interstitial tissue, and Leydig cells having many microvilli in their surface were almost round in shape. Both bundles of collagen fibers and networks of reticular fibers were observed around the Leydig cells. The capillary in the interstitial tissue of the boar was a muscle type, and both pericytes and collagen fibers were observed around the capillaries. The lymphatic capillary was poorly developed in the interstitial tissues of the boar testis. Endothelial cells were the only component of the capillary wall, and anchoring filaments were often observed on the abluminal surface of the endothelium.
