    How many polar body is formed during oogenesis?

    I searched google and it says 3, but I just want to make sure.
    1 from the second meiotic division and 1 from the first meiotic division that then divides again during the second meiotic phase.

    If I am right, there are 3 polar bodies, and as u have outlined the steps and that is how it should form. Unless nature decided not to, there should be 3.

    This is the process that is outlined by the Kaplan/internet/my own :))):

    After the 1st Menarche (1st mensturation),

    One primary oocyte undergoes Meiosis I forming Secondary oocyte and polar body. This polar body undergoes division again to make the count to 2 polar bodies.

    Secondary oocyte is expelled in ovulation, and after Fertilization in (Remember, Meiosis II only takes place after fertilization by sperm), forms the Mature Ovum and Another polar body.

    So, there I think, these are the 3 polar bodies that u have been confused about.
