In oogenesis, the first step is the division of a primary oocyte into a secondary oocyte and a first polar body. This occurs during the first meiotic division, which is initiated during fetal development and is paused until ovulation. The secondary oocyte will then undergo a second meiotic division upon fertilization, resulting in a mature ovum and a second polar body.
