Why does the patient have light menstrual periods that have now stopped? Choose
all the INCORRECT answer(s) from the options below
a) There would be no development of follicles during the follicular phase of the
ovarian cycle
b) The endometrial lining will continue to increase in thickness
c) The cells that produce FSH and LH are located in the hypothalamus and not in
the pituitary gland.

phase of the ovarian cycle.
e) The tumor would only affect the cells the produce the hormone that
stimulates milk secretion.
Which of the following statements accurately describes the pathogenesis of polycystic ovarian syndrome?
Question 28 options:
a)
Excessive androgens that affect follicular decline by suppressing apoptosis, enabling follicles, which normally disintegrate to survive
b)
A decrease in leptin levels that reduces the hypothalamic pulsatility of GnRH, which reduces the number of follicles that mature
c)
A disorder of the anterior pituitary that increases the release of FSH, which reduces the release of LH
