The external prostate of male hedgehogs ( Erinaceus europeus, Hemiechinus sp.) was studied at the beginning and at the end of the breeding seasons. Its tubular secretory units contain two types of epithelia, columnar and stratified. The columnar epithelium has abundant rough endoplasmic reticulum and forms secretory granules. The stratified epithelium undergoes cellular changes culminating in appearance of nuclear and cytoplasmic inclusions, nuclear pyknosis and desquamation of cells and nuclei into lumen. The nuclear inclusions contain protein and abundant silver‐reducing substances. These inclusions may be derived from the residual protein of the nucleus.
