Haematoxylin–Eosin stained sections of Mongolian gerbil ventral prostatic lobe regions. The control prostate tissue of all ages studied presented development characteristic of epithelium (EP) and lumen (L) and stromal compartment (s). Treatments promoted important changes in the epithelial and stromal compartments, mainly in connective tissue in the subepithelial region (*), besides an increase of fibroblasts (arrows) within this area. Morphological modifications occurred in the smooth muscle cells (SMC) during ageing and post-treatment periods. The prostate of animals that received only corn oil did not present either morphological or biometric results significantly different from those of intact animals. Thus, the results obtained in these two groups were aggregated as Control. Barr = 40μm, exception for the Control of Old age where barr = 20 μm.
