During fetal development, primary oogonia undergo mitotic division and then enter meiosis, stopping at prophase I around 7 months of gestation. This process does not continue until menopause, and fully functional ova are not produced at birth. The mitotic division of oogonia results in cells with 46 chromosomes, not 23.
