What happens to oestrogen levels at the menopause and what effect does this have on FSH?
Oestrogen levels fall so FSH levels rise
Is there any remaining oestrogen even though its not being made by the ovaries?
Some oestriol from conversion of adrenal androgens in adipose tissue
Why is a ‘snapshot’ FSH level not used to diagnose menopause?
Ovaries fail gradually and so FSH levels fluctuate daily
What can cause menopause?
- Natural failure of ovaries
- Damage by:
> oophorectomy
> chemotherapy
> radiotherapy
Menopause symptoms?
- Most common > hot flushes/night sweats
- Vaginal dryness/soreness

What local vaginal HRT methods are used to treat menopausal symptoms and benefits/disadvantages?
- Oestrogen pessary/ring/cream
- Has good local effects but minimal systemic absorption
- Need to use longterm to maintain benefit
What systemic treatments are used to treat menopausal symptoms and benefits/disadvantages?
- Oestrogen transdermal patch/gel or oral
- Transdermal avoids first pass (less risk of VTE)
When would you give oestrogen alone, and oestrogen and progesterone together?
- Alone = no uterus
- Combined = uterus present
Why is progesterone used alongside oestrogen if the uterus is present?
Prevents endometrial hyperplasia from unopposed oestrogen
What is the regime of combined HRT in women with some natural ovarian function?
cyclical with 14 days oestrogen then 14 days combined
