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
d)
Testosterone that stimulates androgen secretion by the ovarian stroma and reduces SHBG indirectly
In menstruation, the functional layer is shed from the endometrium. Explain the hormonal and physical factors responsible for this shedding. (See Figure 25.19.)

LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles.
