The ultrastructure of the secretory cells of the ram seminal vesicle was studied on material fixed by immersion or by vascular perfusion. The signs of apocrine secretion seen after immersion fixation did not appear after perfusion fixation and are therefore interpreted as artefacts. Instead, vacuoles with a granule in them were seen. Such vacuoles were observed in the Golgi apparatus and in the apical cytoplasm. Further indications of merocrine secretion were also found. It therefore appears that protein secretion in the ram seminal vesicle follows the typical pattern of serous glands. The possibility that fructose is extruded with the protein as the vacuoles open at the luminal cell surface is discussed.
采用浸泡固定或血管灌注固定的材料，对雄羊精囊分泌细胞的超微结构进行了研究。浸泡固定后所见的顶浆分泌迹象在灌注固定后未出现，因此被解释为人为现象。相反，观察到其中有颗粒的液泡。此类液泡在高尔基体和顶端细胞质中均有观察到。还发现了局部分泌的其他迹象。因此，雄羊精囊中的蛋白质分泌似乎遵循浆液性腺的典型模式。文中讨论了随着液泡在细胞腔面开口，果糖与蛋白质一起排出的可能性。
