Transmission Electron Microscopy of Finasteride + Letrozol-treated Mongolian gerbil ventral prostatic lobe regions. Young (a–b): Enlarged rough endoplasmic reticulum (RER) and secretory vesicles in cell apices. In the subepithelial area, collagen fibrils (CO) increased. Adult. (c–d): RER enlarged cistern occupied the most area among epithelial cytoplasm cells. Increased collagen fibrils (CO) at the epithelial base. Elastic fibre (white arrow). Old (e–f): Basal region of epithelial cells (EP) exhibiting infoldings. Increased amorphous non-fibrillar material (*), collagen fibrils (CO) and fibroblasts (FB) at the subepithelial base. Stroma with increased collagen fibrils (CO) and amorphous non-fibrillar material (*).Basal cell (BC), Smooth muscle cells (SMC).
