Resumo: | The RT of domestic quail from Italian variety showed mainly an albuginic pattern being represented by tortuous channels lined predominately by a simple cubic epithelium. RT channels extended along the testicular albuginea and penetrates into the epididymal region (ER) through its myoconnective matrix. Passageways were continuous to proximal efferent ducts of the ER. Epithelium lining ultrastructure of RT passageways showed some differences between the spring and the inactive phase at middle fall, concerning the quail testicular reproductive cycle. The features observed in RT epitheliocytes in fall were the low cytoplasmic electrodensity, paucity of supranuclear vesicles, which were abundant and variable in form and shape in spring, and some degenerative aspects of cell organelles mainly in ER lamellae. Moreover, presence of apical cytoplasmic extrusions were verified in the fall. No marked features were seen in the RT ultrastructure during the winter and summer comparatively to the active phase of spring. |
