Reproductive Disorders Flashcards
ratio of LH:FSH in early follicular phase
equal days 1-5
granulosa cells make….?
luteal cells make…?
estradial
androgens: DHEA, androstendione, test, progesterone
folliculogenesis growth factors produced by ovary?
inhibin –> inhibit FSH
activin –> activate FSH
Inhibin during different parts of cycle
inhibin a –> luteal phase
inhibin b –> follicular phase
How to evaluate a woman with distrubance in menstrual cycle? (5 things)
- exclude pregnancy with BhCG
- r/o prolactinoma
- androgen levels if hirsutism/acne
- GnRH stim only in precoicious puberty
- Draw LH/FSH in first 5 days after menses
If there’s no menses, what can you use to induce bleeding?
medroxyprogesterone or estrogen + prog to trigger a follicular phase
hypogonadotropic hypogonadism (labs)
- low LH, FSH, estradiol
- amenorrhea
hypothalamic amenorrhea
- acquired GnRH def of pulses
- most common
- due to stress, exercise, poor nutrition
hypergonodotropic hypogonadism (labs)
- high FSH and/or LH
- low estradiol
- amenorrhea
hypergonodotropic hypogonadism (types)
- turners
- premature ovarian insufficiency
premature ovarian insufficiency
Ovarian failure before age 40
-req eventual HRT
signs and sx of POI
- irregular menses without molimal sx
- FSH rise BEFORE LH rise (loss of inhibin)
- look for other AI d/os
hyperandrogenic anovulation - what can cause this?
PCOS
tumors
obesity induced anovulation
PCOS (labs)
timed gonadotropin levels on day 1-5 of cycle
- labs show HIGH ratio of LH/FSH > 2.5/1
- increased androgens: test (ovarian) and DHEAS (adrenal)
risks assoc with PCOS
- endometrial cancer (estrogen unopposed by prog)
- insulin resistance
- htn
- premature cardiac dz
