The structure and distribution of elastic tissue were studied in the limiting membrane of the seminiferous tubule from normal human testis. The elastic and elastic-related fibers (oxytalan and elaunin) were recognized by their tinctorial and ultrastructural characteristics. The connective structures of the limiting membrane, including the fibrotubules and the amorphous material of the elastic system, were studied after tannic acid-glutaraldehyde fixation. Fibrotubules (oxytalan fibers) were observed in almost all intercellular spaces of the limiting membrane, closely related to the contractile cells; the elaunin fibers (patches of amorphous material surrounded by bundles of fibrotubules) were evident in the outermost layers. The function of this system of elastic tissue and myoid cells is discussed, considering the permeability membrane and the role of the myoid cells in the elastogenesis and contractility of the seminiferous tubule.
对正常人类睾丸生精小管的界膜中弹性组织的结构和分布进行了研究。弹性纤维及与弹性相关的纤维（氧化弹性纤维和弹力纤维）可通过其染色特性和超微结构特征识别。在经单宁酸-戊二醛固定后，研究了界膜的结缔组织结构，包括纤维微管和弹性系统的无定形物质。在界膜的几乎所有细胞间隙中均观察到纤维微管（氧化弹性纤维），其与收缩细胞密切相关；弹力纤维（由纤维微管束包围的无定形物质斑）在最外层明显可见。考虑到界膜的通透性以及肌样细胞在生精小管弹性生成和收缩中的作用，对该弹性组织和肌样细胞系统的功能进行了讨论。
