Q

What causes PCOS?

A
  • Multiple ovarian follicular cysts in enlarged ovary form due to hormone imbalance (increase LH; low FSH)
    • LH => theca cells => androgen => 1. hirtuism (body hair); 2. goes to adipose tissue and is converted to estrone (estrogen)
    • Estrone then feedbacks and decreases FSH from AP => - granulosa cells => decrease in estradiol
      • => follicle does not mature => cystic degeneration of the follicle.
