Menopause Flashcards
Agents that reliabily improve \_\_\_\_\_\_\_\_\_\_\_: estrogen acupuncture venlafaxine (Effexor) placebo
hot flashes
the most reliable determinant of whether a woman has reached menopause
LMP 12 full months ago or longer
estrogen+progestin ___________ the risk of colorectal cancer
reduces
most effective therapy for hot flashes
estrogen
dyspareunia can often be resolved with:
vaginal estrogen
normal physiologic change in the HPO axis which causes the ovaries to stop functioning and periods to stop marking the end of reproductive years
menopause
usual age of menopause =
average age of menopause =
48-55
average 51
Diagnostics for ___________
Periods stop for 12 consecutive months w/o taking exogenous hormones (using LMP)
Age
Lab hormone testing (not recommended during perimenopause)
menopause
Hormone Changes during ____________:
Fewer ovarian follicles develop w/ each cycle →
those follicles less responsive to FSH
ovaries have less estradiol, progesterone, and androgens →
negative feedback loop is lost
anterior pituitary production of FSH and LH continues
Perimenopause
Eventually, ___________ stops which causes hormone levels to stop fluctuating making periods stop
follicle production
FSH during ____________:
follicles less responsive to FSH → eventually remains high
Perimenopause
FSH during ____________:
HIGH in response to decreased estrogen → ovarian stromal tissues to increase testosterone production
Increase to >/=30– likely indicates menopause (not required for dx)
Postmenopause
LH during ___________:
eventually remains HIGH
Perimenopause
LH during ___________:
HIGH in response to decreased estrogen → ovarian stromal tissues to increase testosterone production
Postmenopause
Estrogen during ___________:
Ovaries produce less estradiol, progesterone, and androgens so estrogen eventually remains LOW
Perimenopause
most potent form of estrogen, mainly in reproductive years, low in postmenopausal years following the peripheral conversion of androstenedione
Estradiol - E2
estrogen form secreted by the placenta, synthesized from fetal androgens during pregnancy
(Small amounts in nonpregnant women)
By-product of estradiol and estrone
Estriol - E3
weakest form of estrogen, mostly found in postmenopausal women, children, and men. Postmenopause produced by adipose conversion of androstenedione secrete by adrenals (95%) and ovaries (5%) also by the metabolism of estradiol
Estrone - E1
Ovaries no longer produce estrogen or functional follicles when?
after menopause
After menopause, coricostromal and hilar cells of stromal tissue are steroidogenic which leads to significant levels of ___________ and ____________ for many years
androstenedione and testosterone
Circulating levels of this hormone remain relatively constant in PRE and POST menopause partly due to presence of high FSH and LH that cause ovarian stromal tissues to increase production
testosterone
vasodilation that causes hot flashes is result of a surge of ______
LH
increased body temp followed by decreased core temp causes:
night sweats
night sweats along with normal aging lead to less time in sleep stage ___ and ___
3 and 4
