Summary A systematic, comparative study of the accessory sex organs of the adult male rat was carried out after intra-aortic perfusion of the pelvic organs with glutaraldehyde. It has been revealed that although the epithelial cells of the different lobes of the prostate have many features in common, it is also apparent that the cell type of the various lobes have specific ultrastructural characteristics of its own, which morphologically distinguish it from the cell type of the other lobes. I.e.: the different lobes may be identified by their specific ultrastructural feature. It is also striking that the lobes, two-by-two, have so many morphological features in common that they may be divided in 3 subgroups. Based on the appearance of amount and localisation of the different organelles, the cells of the lateral lobe and the seminal vesicle are so alike that they morphologically may be classified as one group. Similarly, the coagulating gland and the dorsal lobe form another group, while the ventral lobe as a single form a third group. The few biochemical data from the different lobes which are accessible, seem suggestive to support this subgrouping. Since the various prostate lobes and the seminal vesicles have their homologies in man, further investigation both morphologically and biochemically should be concentrated upon the different groups instead of the single lobe. The study, which describes the different lobes and cell types in detail also show structures which have not been demonstrated within the prostatic epithelium before.
