Caption: Human egg cells. Coloured scanning electron micrograph of the surface of the ovary of an embryo 7-8 weeks after fertilisation. Several primordial egg or germ cells (red), also known as oogonia, are here visible; they have migrated from the yolk sac into the ovarian cortex where they multiply by mitosis. By the fourth and fifth months of foetal development the primordial germ cells number about 7 million but of these only 1 million will be present at birth. By this stage they are known as primordial follicles and will represent the patrimony of eggs in the woman's ovaries. Magnification: x1900 at 6x7cm size.
