Menopause Flashcards
1
Q
What is menopausal transition?
A
- regular periods to irregular periods to when periods stop
- AKA perimenopausal
2
Q
What is menopause?
A
- stopping menstruatin bc of loss of ovarian follicular function
- no period for 12 months (amenorrhea)
3
Q
What is premature ovarian failure?
A
- premature menopause
- before age of 40
4
Q
What are the symptoms of menopausal transition?
A
- hot flushes
- reduced cycle length
- irregular periods
- atrophic vagina post menopause
- impaired fertility leading up to menopause
- mood symptoms
- urinary complaints
- sleep disturbance
- vasomotor symptoms
5
Q
What is atrophic vagina?
A
- vaginal thinning, drying and inflammation of the walls bc of less oestrogen
- painful sex
6
Q
What is a follicle?
A
-oocyte surrounded by granulosa and theca cells
7
Q
What happens to the number of follicles as we age?
A
- Fetus= 7 million
- birth= 1 million
- Puberty= 400 000
- menopause= 140
- post menopause= hardly any - maybe like 1
8
Q
Why is menstruation stopping not a reason for menopause?
A
- average woman has 444 cycles in her life
- so only 444 eggs lost through cycle
- so at menopause there are still between 1 and 140 eggs left, so periods stopping is not the reason for menopause
9
Q
Why do the eggs die as we age?
A
- apoptosis
- breakdown
- smoking causes menopause 2 years early
10
Q
What are the effects of granulosa cells?
A
- produce AMH
- secrete inhibin B
11
Q
If you have less granulosa cells because of follicle depletion, what happens?
A
- less AMH
- less Inhibin B
- less Inhibin A
12
Q
What is the role of AMH?
A
men= regress mullerian duct women= inhibit excess FSH
13
Q
What happens if AMH reduced?
A
- excess FSH
- this means more (than required) follicular recruitment
- more follicle loss
14
Q
What does Inhibin B do?
A
Inhibits FSH production
15
Q
What happens if you have low Inhibin B?
A
- more FSH
- more follicular recruitment
- more follicle loss
- so as woman gets nearer to menopause age, she has more menstrual cycles that have no ovulation in them
