  1. Menstrual history
  2. Cervical smear history
  3. Sexual history and contraception history
  4. Previous treatment or surgery


What are the key symptoms and signs of anorexia nervosa?

  1. Weight loss
  2. Lethargy
  3. Pallor of skin and conjunctiva
  4. Lanugo on face, arms and back
  5. Halitosis
  6. Low BMI


What are the possible differential diagnoses for anorexia nervosa?

  1. Depression
  2. Pregnancy
  3. Bulimia nervosa
  4. PCOS
  5. Chronic disease e.g. CKD
  6. Premature ovarian failure
  7. Hypothyroidism


At a very low body weight, how is GnRH secrection impacted in females and what is the impact of this?

It is decreased

FSH and LH secretions decline


Premature ovarian failure is associated with _________ symptoms

Premature ovarian failure is associated with menopausal symptoms

(night sweats, hot flushes, modd swings)


What are the key differential diagnoses for premature ovarian failure?

  1. Pelvic inflammatory disease
  2. Hyperprolactinaemia
  3. PCOS
  4. Pregnancy



Why does hyperprolactinaemia result in amenorrhoea?

  1. High levels of prolactin inhibit GnRH
  2. Levels of LH and FSH fall


What are the main causes for premature ovarian failure?

  1. Idiopathic
  2. Genetic (Turner's syndrome)
  3. Autoimmune (adrenal insufficiency and thyroid disease)
  4. Iatrogenic


Due to decreased oestrogen levels associated with premature ovarian failure, which signs and symptoms can be expected?

  1. Hair thinning
  2. Atrophic vaginitis
  3. Menopausal symptoms


Oestrodiol protects against what?

Bone and CV disease


In patients with primary ovarian failure, FSH and LH levels are _______

In patients with primary ovarian failure, FSH and LH levels are high


Ovarian failure is indicated by a FSH level of what?

>30u/L on 2 separate occasions

(normal level 2-8u/L; rises due to negative feedback as there is low oestrogen)


What is the main treatment option for premature ovarian failure?

Oestrogen-progestin replacement therapy (HRT)


What does oestrogen-progestin replacement therapy involve when used for premature ovarian failure?

  1. Oestrogen alone (days 1-14)
  2. Oestrogen and progesterone (days 14-28)

This (progesterone) causes a monthly bleed and has a protective effect on the endometrium


Oestrogen-progestin replacement therapy has which beneficial outcomes?

  1. Prevents osteoporosis
  2. Controls symptoms e.g. vaginal dryness
  3. Lowers CV risk


Why does hyperinsulinaemia cause increased androgen production?

Theca cells are stimulated by insulin


Free androgens and oestrogen rise for which reason in PCOS?

Sex-hormone binding globulin production decreases


Why can PCOS result in amenorrhoea?

High levels of oestrogen and androgens inhibit LH and FSH


PCOS may be associated with which skin change associated with insulin resistance?

Acanthosis nigricans


What is the most appropriate test for PCOS?

Transvaginal ultrasound

(normally shows bilateral ovarian cysts)


Which lifestyle factors can be used to manage PCOS?

Moderate weight loss


Which medical therapies can be used to manage PCOS?

  1. Ovulation induction medication (Clomiphene)
  2. Ovarian drilling
  3. Metformin (to help insulin sensitise)
  4. Oral contraceptive pill
  5. Anti-androgens (Cryproterone, Ethinylestradiol)
  6. Cosmetics and topical agents
