premature menopause occurs before age […]

perimenopause begins with variation in cycle greater than […] days associated with increased […]
seven
FSH
which phase of menopause is the most symptomatic for women?
perimenopause
average age of onset of menopause
51
FSH consistently elevated over […] is considered diagnostic for menopause
30
menopause before age 40 suggests
primary ovarian failure
cause early induction of menopause
radiation
chemotherapy
bilateral oophorectomy
source of estrogen after menopause
peripheral conversion of androgens
what would you expect to see for FSH, LH, GnRH, and estrogen in a menopausal female?
FSH very high
LH high (no surge)
estrogen low
GnRH high
symptoms of menopause
Hot flashes
Atrophy of
Vagina
Osteoporosis
Coronary artery disease
Sleep disturbances
causes HAVOCS
how can early menopause result in shorter cycles?
as follicles decrease –> decreased inhibin –> less negative feedback on hypothalamus –> more FSH released
when the cycle length shortens, it is called
LOOP: luteal out of phase
what leads to the loss of LH surge in menopause?
GnRH pulses slow, but more GnRH is released
alterations of GnRH pulse cause this
is AMH useful in predicting when menopause will occur?
no
in premenopause […] is the dominate estrogen type
however, in post menopause it is […]
estradiol
estrone (formed via peripheral metabolism)
(ratio reverses after menopause)
most common cause of AUB
bleeding due to anovulation
in the workup of AUB endometrial biopsy is important to rule out [2]
endometrial hyperplasia
malignancy
most common symptom of menopause
sudomotor symptoms (hot flashes)
physiologic mechanism of hot flashes
estrogen narrows the thermoneutral zone
serum estrogen levels [are/are not] predictive of hot flash frequency
are not
treatment of hot flashes
lifestyle modifications
SSRI, gabapentin, clonidine
the sudomotor symptoms of menopause tend to […] over time, while the vulvo-vaginal symptoms […]
get better
progressively worsen
people with surgical menopause [are/are not] considered to have POI
are not
diagnosis of POI requires a minimum of […] bleeding abnormally and at least […] FSH levels drawn at least 1 months apart
4 months
2
why should patients with POI not desiring pregnancy still be on contraception?
ovary can occasionally ovulate
HT used to protect women with a uterus from endometrial cancer
estrogen-progesterone therapy
HT consisting of hormones chemically identical or very similar to those made in the body
bioidentical hormone therapy
(generally not recommended by ACOG unless dosing is not commercially available or there is an allergy)
HT useful for perimenopausal transition to treat symptoms and prevent bleeding and pregnancy
hormone contraception
