The distal segment of the human male urethra, in particular the fossa navicularis, was studied with light- and electron microscopy as well as by means of histochemical and immunocytochemical methods. The fossa navicularis of the urethra contains a circumscribed zone of extremely thick, non-keratinized stratified squamous epithelium composed of cells containing a large amount of glycogen. These the prostatic part of the male urethra, about 2.5 cm in length, that traverses the prostate; it includes the seminal colliculus, and the ejaculatory and prostatic ducts open into it.
