The mouse epididymis, consisting of a head, body and tail, was examined by electron microscopy. The principal cells of the epididymal duct in the epididymal body have rod-shaped inclusions, 0.3 to 1.0 microns in diameter and 2 to 5 microns in height. The inclusions contain a bundle of tubules, about 40 nm in diameter, with a wall about 6 nm in thickness. The tubules are regularly arranged in a hexagonal pattern. A goniometric study of the inclusions shows evidence that the wall of the tubules consists of filament-like subunits which run parallel to each other and are inclined at about 25 degrees to the axis of the tubules, forming loose spirals. The inclusions occasionally contain material similar to that in the lysosomal bodies. These inclusions were observed in every epididymis examined, and seem to be related to the specific functions of the principal cells in the epididymal body.
通过电子显微镜检查了由头部、体部和尾部组成的小鼠附睾。附睾体中附睾管的主细胞含有杆状内含物，直径为0.3至1.0微米，高度为2至5微米。这些内含物包含一束小管，直径约40纳米，管壁厚度约6纳米。小管以六边形模式规则排列。对内含物的角度测量研究表明，小管壁由丝状亚基组成，这些亚基相互平行排列，并与小管轴成约25度角倾斜，形成松散的螺旋。内含物偶尔含有与溶酶体中物质相似的物质。在每个检查的附睾中都观察到了这些内含物，它们似乎与附睾体主细胞的特定功能有关。
