Electron microscopic observations of the lymphatic vessels of the mammalian testis

This paper is a report on preliminary investigations into the morphology of elastic fibers surrounding the lymphatic vessels of the testis, and it includes a description of the three-dimensional architecture of the lymph vessels and elastic fibers of the mammalian testis obtained by indirect injection of glutaraldehyde and Mercox. Different types of filaments and blind ends were observed. The filaments repeatedly divide and fuse to form the reticular networks. These networks provide a specific microenvironment for the lymphatic vascular system under different physiological and pathological conditions.
