Q

List several disorders of sexual development and their pathophysiology.

A

Turner syndrome: 45XO. Ovarian agenesis.
46 XY gonadal dysgenesis: no testes develop, so phenotypically female
46 XY DSD (aka CAIS- complete androgen insensitivity syndrome). No AR response to androgens –> no virilisation despite formed testes.
46XX DSD (aka CAH). Lack of cortisol forming enzyme eg. 21 hydroxylase –> increased testosterone and virilisation.

Q

When is IVF indicated? What are the basic principles (explain to a patient)?

A

Indicated if tubal disease, failure to respond to OI/IUI, egg donation, need for PIGD
You will need to administer injections of hormones every day for about two weeks, which we will teach you how to do (very easy and not painful). During this time you will come in every other day to have a scan and blood tests to monitor your eggs. Then, we will give you a ‘trigger’ injection of a different hormone and then collect the eggs about 36 hours later in an operation.
The eggs will be combined with the sperm in the lab to fertilise them. We will then implanted one or two of these embryos into your womb. You may be given more hormones to take after this.

Q

A 33 year old woman sees you in gynae clinic because she is having trouble conceiving. Her and her partner have been trying for 7 months. The GP has referred her because she had PID 7 years ago and needed admission to hospital. What investigations would you consider doing for this woman?

A
  • Want to determine if she is ovulating. If she isn’t, then this needs to be addressed first. eg. cycle history, day 21 progesterone
  • Tubal patency testing: in this case, because there is a known history of PID, this patient should be offered laparoscopy + dye for Ix of tubal patency.

In cases where there is no history/RFs for tubal factor: consider hysterosalpingogram (HSG) with Xray or hysterosalpingo-contrast-syntography with USS

17

A

Anti-oestrogen

Works at the hypothalamus + pituitary to prevent negative feedback of oestrogen –> FSH +LH –> ovulation

23
Q

Define the menopause. What is the average age of the menopause in the UK?

A

Cessation of menstrual periods, diagnosed after 12 months of no bleeding.
51

24
Q

What is the perimenopause? What is another name for this?

A

The time between the onset of ovarian dysfunction and the diagnosis of menopaise (1 year after periods stop). Also known as the climacteric.

25
Q

Describe the hormonal changes during perimenopause.

A

As ovarian reserve decreases, there is less oestrogen and inhibin B produced.
This results in an increase in GnRH pulsatility, which increases FSH and LH levels.
Testosterone also declines with age, while progesterone can be unpredictable.

26
Q

How is menopause diagnosed?

A

Usually a clinical diagnosis if the woman is >45. If younger, hormone levels (FSH and oestrogen) should be measured.

27
Q

A 49 year old woman comes to see you in the GP clinic and says she is having difficulty with hot flushes. They are causing her to have poor sleep, which is impacting her work performance. What would you like to ask her about?

A
  • Hot flushes: when did they start, how have they changed over time, any triggers (caffeine, alcohol, smoking), how much is she sleeping, taking anything to help with symptoms?
  • Periods: LMP, regularity, length, bleeding, PMB
  • Other menopausal symptoms: poor concentration and memory, mood, libido, vaginal dryness + dyspareunia, urinary symptoms
  • PMH including gynae, clots, cancers, CVD. BMI, BP.
  • DHx, allergies
  • FHx: clots, cancers, osteoporosis, CVD
  • SHx: impact on life. Smoking
28
Q

A 52 year old woman comes to see you in the GP clinic because she has not had a period in 4 months. Prior to this, she says she was having irregular periods, with varying cycle length and bleeding pattern. What information and advice would you like to give her?

A
  • Want to ask about menopause symptoms and effect on life to determine desire for HRT. Also relevant medical history if HRT is being considered
  • Explain what menopause is, common symptoms and complications (hot flushes + night sweats, low mood, poor concentration + memory, aches + pains, vaginal dryness, sexual difficulties)
  • Lifestyle changes to reduce symptoms and consequences (diet + exercise to maintain healthy weight + reduce heart disease + bone health
  • Discuss options for treatment
  • Discuss contraception
29
Q

What are the contraception options for perimenopausal women? When should contraception be stopped?

A
  • Barrier methods eg. condoms. For all women who are sexually active at risk of STIs
  • Copper IUD: suitable from 40-menopause
  • Mirena: suitable from 45-55
  • Progestogen-only implant: suitable, no increased risk
  • Depot injection: increasing risk, consider alternatives
  • COCP/progestogen mini pill: suitable. COCP 1st line. Stop COCP at 50 years

Women can stop using contraception at 55 years, even if still bleeding. If at risk of STIs, still continue condom use.

30
Q

What is premature ovarian insufficiency? How is it diagnosed?

A

Decline in ovarian function in women under the age of 40.

Symptoms or menopause/menstrual disturbance AND raised FSH on 2 occasions 4-6 weeks apart.

31
Q

Name some causes of premature ovarian insufficiency

A
  • Turner’s syndrome
  • Fragile X syndrome
  • Idiopathic
  • Iatrogenic: radiation, chemotherapy, oophorectomy
  • Immune-mediated
32
Q

What is the management of POI?

A

Very important to give HRT until the age of the natural menopause
The forms of HRT available include the COCP (higher levels of hormones than normal HRT, may be preferred for younger women), oral or transdermal (patches or creams) HRT. HRT is not a contraceptive, and there is still a small risk of pregnancy in POI so this needs to be considered.

33
Q

When should HRT be offered? What types of HRT are there and what are the advantages and disadvantages of each?

A

HRT should be offered to all women with POI, and any women who are having difficulty with symptoms of perimenopause.

Vaginal oestrogen creams: good for vaginal dryness and GU symptoms. Does not work for vasomotor/psych symptoms. Safe, no risk of clots/cancers.

Systemic HRT (oral or transdermal)

  • Risks: clots, CVD (stroke), breast cancer
  • Benefits: decrease menopausal symptoms, reduce osteoporosis during treatment
  • Transdermal >oral: lower risk of clots and stroke
34
Q

What are the preparations of oral HRT?

A

Cyclical or continuous.

  • Cyclical: useful for women still having periods. Take oestrogen only tablets for the first half of the cycle, then progesterone + oestrogen for the 2nd half -> period. Also in 3 monthly forms if irregular periods.
  • Continuous: for women with no periods. Taken every day
35
Q

A 52 year old woman sees the GP because of vaginal dryness, low mood, and poor concentration. She says she does not feel like herself and would like to try HRT. She has not had a period for 1 year. There are no contraindications in her history to HRT. How would you counsel this patient?

A
  • Confirm she has gone through menopause
  • There are several ways we can help with her symptoms
  • Options: vaginal oestrogen creams to help with dryness, systemic HRT
  • HRT benefits: reduces symptoms, can reduce risk of osteoporosis while on treatment
  • HRT risks: increased risk of breast cancer, blood clots, CVD if older aged (60s)
  • It is normal to have some abnormal bleeding during the first 3 months of use. After this time, it is important to talk to your doctor quickly if you experience bleeding
36
Q

What are the contraindications to prescribing HRT?

A

For any women with menopausal symptoms and contraindications to HRT, refer to gynae.

  • Current or previous breast cancer or endometrial cancer
  • Liver disease
  • Thrombophilia
  • Previous VTE
  • Family history of VTE/cancer **caution, refer to haem?
