The primordial germ cell is converted into oogonium through very cytoplasmic changes . The oogonium increase in its size in the cytoplasm resulting in the formation of primary oocyte . The primary oocyte undergoes the first meiotic division resulting in the formation of a secondary oocyte and first polar body. The secondary oocyte undergoes the second meiotic division resulting in the formation of mature oocyte or ovum and second polar body . The first polar body undergoes the meiotic division resulting in the formation of two further polar bodies .
