      - oocyte enlarges
    - - granulosa cells: multilaminar follicular layer
      - stroma cells --> theca interna, theca externa
    - - antrum: cavities form between granulosa cells
- - - - oestrodiol 17-b
      - +ve/-ve feedback for hypothalamus + ant pit depending on levels

        androgen
    - - luteal cells
        
        progesterone
        
        high levels --> -ve feedback on ant pit + hypothalamus
- - - - youngest cells
      - high nuclear to cytoplasmic ratio
    - - healthiest, smallest
      - high N/C ratio
      - uniform in shape and size, round or slightly oval
    - - decreased N/C ratio, large amounts of keratinized cytoplasm
    - - oldest
      - dead cells, line vaginal lumen
      - sharp, flat, angular
    - - cytoplasmic vacuoles
