WebThe formation of ova in the ovary from primordial germinal cells is said to be oogenesis. It is completed in three steps: (1) Multiplication phase: The germinal epithelium cells of the ovary multiply by mitotic divisions to form a small cluster of cells known as follicles. A single cell from the follicle differentiates and form oogonium.
