Flashcards in Ovary Deck (9):
1

Hormone levels in polycystic ovarian syndrome

high LH to FSH
LH:FSH > 2

2

These hormones act on which cells/which actions
LH
FSH
estradiol

LH: theca cells to release androgens
FSH: granulosa cells to convert androgens -> estradiol
estradiol: induces LH surge

3

Residual ovarian follicle ie corpus leuteum secretes what

progesterone
functions to drive secretory phase and prepare endometrium for possible pregnancy

4

Non-pathological ovarian cysts result from what phenomenon

degeneration of follicles
occasionally forms cysts that are insignificant

5

How does a high LH: FSH ratio cause multiple cysts to be created

low levels of FSH cause degeneration of the follicle
form may cysts

6

High LH in PCOD causes

theca cells to secrete excess androgen
hirtuism --> excess hair in male distribution

7

Low FSH in PCOD causes

degenrations of follicles (not stimulated)
formation of ovarian cysts as a result

8

Fate of androgens in PCOS

converted to estrone in adipose tissue
increases risk for endometrial carcinoma
due to high levels of estrogen

9

Sx of PCOS

hirsutism, infertility, oligomenorrhea
insulin resistance possible --> T2D
