What can fertility awareness methods be based on?\
What cancers does COCP increase and decrease the risk of?
Advantge of Depo Provera compared to COCP? Disadvantage?
What is another high dose and low dose progesterone contraception?
Difference in primary action of IUS vs IUD?
Give two disadvantages.
Cervical mucus
Basal body temperatures
Length of menstrual cycle
Decrease ovarian and endometrial
Increased cervical and breast
IM injection every 12 weeks - therefore reliable as long as appointments are attended
Delay in fertility returning (10months)
Appointments needed every 12 weeks.
High dose - implant
Low dose - progestogen pill
IUS - prevents implantation through reduced endometrial proliferation
IUD - copper toxic to sperm and ovum
Uterine perforation
Insertion may be unpleasant
Menstrual irregularity
Infertility
Give two testicular causes for infertility.
Pre-testicular?
Post-testicular?
Klinefelter syndrome
Cryptorchidism
Torsion
Varicocele
Hyperprolatinaemia
Diabetes
Erectile dysfunction
Ejaculatory failure
Amenorrhea.
Give some causes of primary amenorrhea.
Secondary.
Mullerian agenesis
Vagina atresia
Swyer syndrome
Turner syndrome
Asherman’s syndrome PCOS Stress, eating disorders Hyperprolactinaemia Anovulation
Endometriosis
Typical symptom?
Main pathophysiological theory?
Mullerian abnormalities.
Give 3.
Chronic pelvic pain
Retrograde menstraution from uterus into Fallopian tubes and peritoneum.
Bicornuate uterus Didelphys - dupilcation of the uterus cervix and vagina Septate uterus Uterine hypoplasia Agenesis
What are some blood tests to carry out in someone who is experiencing subfertility?
What can be used to test tubal patency?
When should referral to a fertility clinic be made?

Prolactin, androgens, TFTs
Hysterosalpingogram
Reproductive age women who has not conceived after 1 year of unprotected vaginal sex intercourse.
Early is they are over 36 years old
Preeclampsia.
What is eclampsia?
Why hypertension occurs?
Two complications of severe preeclampsia.
Where is pain?
Why elevated liver enzyme?
Pathophysiology behind HELLP syndrome?
Why may seizures develop?
Tx?
Preeclampsia + seizures
Pro-inflammatory molecules are released form non-functional placenta leading to endothelial dysfunction and increased salt retention.
haemorrhagic stroke
Placenta abruption
RUQ pain due to swelling and injury to the liver as a result of vasospasm occurring.
Elevated liver enzymes as a result of this
Haemolysis due to small microthrombi forming
Cerebral edema occurs
Delivery of foetus and placenta
Why do you get a respiratory alkalosis in pregnancy?
Why does TV increase?
TV increased more CO2 breathed off - gradient formed for CO2 removal from the foetus.
Progesterone effects on central respiratory centre
Oxygen consumption and CO2 production increased

Give some examples of dysfunction uterine bleeding?
Why depression/ insomnia?

Longer and shorter cycles
Because reduced sleep due to night sweats
Decreased libido due to vaginal dryness
Because LH and FSH production is high.
