Oogenesis is defined as the creation of an ovum.

It is the female process of the male process of gametogenesis

Occurs in the ovarian follicle.

The beginning step is referred to as Oocytogenesis
-  this is a transition step prior to birth
-  this is the development of oocytes

The next step is Ootidogenesis
  -  Oocytes turn to ootid
-  controlled by meiosis
-  It continues up until prophase I

Meiosis I
-  is a division of number of chromosomes
-  the number is cut into half
-  is essential for sexual reproduction

Steps of Meiosis are:

1.)  Prophase
2.)  Metaphase
3.)  Anaphase
4.)  Telophase

Meiosis II

-  starts after Meiosis I
-  continues until metaphase II
-  when this meiosis II is finished then result is ootid and a polar body

Maturation

-  Polar bodies dissolve leaving only ootid
-  Ootid will mature into the ovum
