The ducts of the rat ventral prostate have been studied by light and electron microscopy for elucidation of their role in prostatic function. The epithelium of the main duct consists of simple columnar cells and polymorphic basal cells. The columnar cells show no indication of secretory activity. The basal cells contain bundles of filaments of 5--6 nm thickness and numerous pinocytotic vesicles. The ducts are surrounded by layers of circular smooth muscle cells interspersed with nerve axons. On ultrastructural grounds the ducts do not appear to secrete material into the seminal fluid, but apparently the muscular coat actively helps drain the gland during ejaculation.
为阐明大鼠腹侧前列腺导管在前列腺功能中的作用，已用光学显微镜和电子显微镜对其进行了研究。主导管的上皮由单层柱状细胞和多形性基底细胞组成。柱状细胞未显示出分泌活动的迹象。基底细胞含有厚度为5 - 6纳米的成束细丝和大量吞饮小泡。导管被散在神经轴突的环形平滑肌细胞层所包围。从超微结构来看，导管似乎并不向精液中分泌物质，但显然肌层在射精时积极协助腺体排空。
