Das Nebenhodengangepithel der Ratte nach Hypophysektomie und nach Androgensubstitution

Summary The epithelium of the epididymal duct (corpus region) of the rat after hypophysectomy and after androgen substitution has been examined by light and electron microscopy. The epithelium consists of 3 different cell types: principal, accessory (Nebenzellen), and basal cells. The characteristics of these cells disappear after hypophysectomy and redifferentiate after androgen application. The alterations of the principal and accessory cells in course of time (from the 1st week up to 9 weeks after injection of 20 mg testosterone propionate) are the subject of this report.
