The growth of previtellogenic oocytes in reptiles and birds is closely accompanied by the origin, multiplication and accumulation of organelles, RNA’s and lipids of diverse morphology and chemical nature that first accumulate in the juxtanuclear cytoplasm of young oocytes, where they constitute Balbiani’s vitelline body, which acts as the initial centre of great metabolic activity, as evidenced by the multiplication of various organelles. The factors that initiate the formation of Balbiani’s vitelline body are yet to be determined, but with further growth of the oocyte, its components are dispersed in the outer ooplasm to occupy specific regions of the growing oocyte.
