Menopause, PCOS and infertility Flashcards
Define perimenopause
the period when ovarian function declines and menopausal symptoms appear
describe what happens during perimenopause on a hormonal level?
gradual rise in FSH
fluctuations in E2 and progesterone
decreased ovarian inhibin
gradually E2 becomes very low
what FSH levels define non-menopause, perimenopause and post menopause?
non-menopause i.e. still cycling= FSH less than 10u/L
perimenopause= FSH > 20u/L
post menopause= FSH > 40u/L
what are the short-term effects of menopause?
Vasomotor symptoms- hot flashes, night sweats, formication
Vaginal dryness–> dyspareunia, dysuria, urgency
Sleep disturbance
what are the long term effects of menopause?
reduced bone density
what lifestyle advice might we give to a post menopausal woman to help reduce her risk of osteoporosis?
weight bearing exercise > 3 times per week
calcium intake 1200mg/day
adequate vitamin D
avoid excess alcohol and smoking
what are the causes of premature menopause?
primary ovarian insufficiency
iatrogenic causes- e.g. surgical/chemo/radiotherapy
Genetic causes- turner’s, fragile x
autoimmune causes
what is the criteria diagnosis for premature menopause?
at least 4 months of amenorrhea prior to age 40yrs
+
FSH > 40 U/L on 2 occasions at least 1 month apart
+
exclusion of secondary amenorrhoea causes
what are the risks of oestrogen alone HRT?
increased risk of stroke, VTE, PE, DVT
increased risk of cholecystitis
unopposed E2 in presence of uterus can cause endometrial hyperplasia
what are the risks of oestrogen +progesterone HRT?
increased risk of stroke, VTE, PE, DVT
increased risk of cholecystitis
increased risk of breast cancer if used for > 5 yrs
if a perimenopausal women complains of vaginal dryness but has a significant hx of IHD, would you commence HRT?
more consideration is indicated
generally caution AGAINST using HRT
but if must, transdermal route may be preferable
what drug is Livial?
tibolone, a synthetic steroid with weak oestrogen, progesterone and anti-androgenic action
what is the difference between vagifem and ovestin cream?
vagifem= estradiol
ovestin= estriol
what are some ix you need to order in a 38 yr old woman who you suspect is going through premature menopause?
- Check FSH > 40 on two occasions
- Exclude secondary causes of amenorrhoea such as PRL, TFTs, bHCG
- Establish any genetic abnormalities such as Fragile X, Turner’s syndrome–> do a karyotype
Do an autoimmune screen including thyroid antibodies, gastric parietal cell autoantibodies
what are the long term consequences of premature menopause?
increased risk of CV disease
increased risk of osteoporosis
infertility
what FSH level (low or high) do we expect in a woman with ovarian failure or HPG axis dysfunction causing anovulation?
what if the FSH level was normal but the woman is still anovulating? what must we consider?
FSH= high if Ovarian failure
FSH= low if HPG axis dysfunction
FSH= normal if PCOS/obesity
What biomarker indicates ovarian reserve? How else can we test for ovarian reserve?
anti-mullerian hormone- low AMH may indicate low ovarian reserve
more common test for ovarian function or reserve- is the day 3 FSH and LH. High FSH > 10 may indicate poor ovarian reserve
what are some things we should ask about the male partner when consulting about infertility?
Has he fathered any children from previous relationships?
Smoking, drug and alcohol intake, anabolic steroid use
Past STI history
Ability to sustain erection and ejaculation during intercourse
Past history of mumps, undescended testes, genital trauma or surgery including vasectomy
what are some key things to examine for in a male partner if a couple come in with the issue of infertility?
Body habitus, height, weight, BMI, muscle mass and strength, fat distribution
Secondary sexual characteristics: hair thickness and distribution
Breasts (gynaecomastia), signs of endocrinopathy
Blood pressure lying and standing
Inguinal canals
As indicated, testicular examination: determine size (with aid of orchidometer), consistency, masses, hydrocoele, varicocele
a woman comes in to see you because she has been having difficulty conceiving over the past year. what on general history do you want to know?
Maternal Age
Past reproductive history and previous pregnancy outcomes
Past gynaecological history
Menstrual history, including frequency and regularity, symptoms of ovulation
Sexual history: frequency, problems, lubricant use, timing in fertile window
- Weight gain, acne, hirsutism
- Dyspareunia, dysmenorrhoea
- Galactorrhoea, visual disturbance
- Contraceptive history: type and duration
- Past STI history, previous PID
- Medical, surgical, psychiatric, general health
- Family history, genetic illness
- Medications, smoking, drug and alcohol intake
how might we determine whether a woman is ovulatory or anovulatory as an ix for cause of infertility?
Mid-luteal progesterone (day 21) if high then indicates that ovulation has occured
how might we assess tubal patency as a possible cause of infertility?
hysterosalpingogram or saline sonohysterography
what are some associated female conditions to screen for in a woman who is presenting with difficulty conceiving?
PCOS-acne, hirsutism, weight gain
endometriosis- dysmenorrhoea, dyspareunia
why is anabolic steroid use in males associated with infertility?
Anabolic steroid abuse results in hypogonadotrophic hypogonadism due to the negative feedback of high androgen levels
what exactly is the mechanism of infertility in kallman’s disease?
absence of GnRH releasing neurons at the hypothalamus
what are some causes of testicular failure leading to infertility?
congenital genetic causes e.g. kleinfelter’s
acquired causes: mumps, trauma, torsion, chemotherapy/radiotherapy
if a man had testicular failure causing infertility, what would show up on his LH/FSH blood test?
raised LH/FSH often with normal T levels
what is the relationship between CF carrier state and infertility in males?
Congenital bilateral absence of the vas deferens can occur and is associated with the cystic fibrosis carrier state.
what progesterone level in the mid-luteal phase is indicative of ovulation?
A progesterone level over 20 nmol/L in the mid-luteal phase is a reliable indicator that ovulation has occurred.
