  5. True or false

    true
  6. Low levels of estrogen triggers the hypothalamus to release ______
    GnRH
  7. Low levels of estrogen triggers the hypothalmus to release GnRH that inluences the _____ to release hormones.
    APG
  8. Low levels of estrogen triggers the hypothalmus to release GnRH that inluences the APG to release hormones such as _____ and _____
    FSH and LH
  9. _____ triggers the increase of estrogen

    fsh / lh
    fsh
  10. _____ triggers the increase of progesterone
