Flashcards in Menopause Deck (20)
Other than infertility, what are 4 morbidities associated with menopause (both pre-mature and normal)?
Urogenital atrophy (see atrophic vaginitis on wikipedia)
Reduces Quality of Life
What's going on in the ovary between infancy and menarche?
Waves of follicular development and atresia are happening - there's just no ovulation / hormone production because not getting FSH / LH from the pituitary.
Does the rate of follicular atresia stay constant post-menarche?
Nope, it accelerates 10-15 years before menopause (correlated with decreased fertility).
How is menopause defined? Is it often abrupt?
12 months of amenorrhea.
No, abrupt cessation of periods is rare, there's often a perimenopausal transition with irregular periods / menopause symptoms.
What's the mean age of menopause, across many different studies?
About 51 years old.
What are biochemical characteristics of menopause?
High FSH and LH, low estrogen.
4 factors affecting age of menopause onset?
Smoking (hastens onset by about 1.5 yrs)
Dietary (vegetarians hit menopause earlier)
Alcohol (may delay menopause)
Effect of menopause on CV risk factors?
LDL and total cholesterol increases approaching and after menopause.
Metabolic syndrome rates go way up post-menopause.
Is post-menopausal osteoporosis a big problem?
5 types of symptoms associated with menopause?
3 risk factors for menopause symptoms? (MoA for one of them?)
Smoking -> revs up p450 enzymes that degrade estrogen.
Race -> AA have more symptoms vs. white and Asian.
Best treatment for menopause symptoms?
Hormone replacement therapy appears to be best.
SSRIs, antihypertensives, behavioral changes (diet, exercise, etc.)
How is premature ovarian insufficiency defined?
Cessation of ovarian function before age 40.
How is premature ovarian insufficiency diagnosed?
2 separate measurements 1mo apart of elevated FSH and LH with decrease estrogen.
5 causes / risk factors for premature ovarian insufficiency?
Iatrogenic (chemo / radiation Tx)
One notable chromosomal etiology of premature ovarian insuffiency?
Turner syndrome: 45X
(or 45X mosaicism)
Turner's syndrome? But what about the lyonization of 1 X chromosome?
Both X chromosomes are needed for ovarian function - neither is lyonized there.
What cells may be most damaged by chemotherapy? What chemotherapeutic agents seem to be worst?
Early granulosa cells of primordial follicles may be most susceptible.
Alkylating agents seem to do the most damage.
Major risk of hormone replacement therapy?
Increased risk of DVTs.
