Abstract

The purpose of the study was to determinate the morphometric parameters of epithelial cords, prostatic ducts, acini of the human prostate gland and their lining epithelium, the shape of prostate glands and muscle tissue in fetal periods of development. The study was performed on 19 prostate glands of boys of intermediate and late fetal periods. The formation of prostatic ducts was not followed by increase in their total area and was the result of differentiation epithelial cells and apoptosis. Transformation of prostate glands in the prenatal period occurs in a certain sequence: the formation of epithelial buds, their canalization by apoptosis with formation of epithelial ducts and prostatic ducts and formation of end pieces of prostate glands from these ducts. In prenatal periods, the structure and orientation of smooth muscle bundles around the glands can not provide evacuation of the contents of the prostate glands.
