3

Cessation of periods for greater than 6mths in someone who has previously had a period

4
Q

What is the main cause of primary amenorrhoea?

A

Congenital abnormality

Turner’s, Kallman’s

5
Q

List ovarian causes of secondary amenorrhoea

A

Polycystic ovarian syndrome

Ovarian failure

6

A

True

7

What triad of symptoms are classic of amenorrhoea/oestrogen deficiency?

A

Flushing
Lack of libido
Dyspareunia (painful sex)

8
Q

List investigations that all patients with oligo-/amen- orrhoea get

A

LH, FSH, oestradiol levels
Thyroid function tests
Prolactin levels

9
Q

List additional investigations for oligo-/amen- orrhoea

A

Ovarian USS, endometrial thickness
Testosterone levels if hirsutism
Pituitary function

10
Q

In primary hypogonadism in females, the problem is arising from where - ovaries or pituitary/hypothalamus?

A

Ovaries

11
Q

In secondary hypogonadism in females, the problem is arising from where - ovaries or pituitary/hypothalamus?

A

Pituitary/hypothalamus

12
Q

Describe LH and FSH levels in primary hypogonadism

A

High LH
High FSH
i.e. hypergonadotrophic hypogonadism

13
Q

Describe LH and FSH levels in secondary hypogonadism

A

Low LH
Low FSH
i.e. hypogonadotrophic hypogonadism

14
Q

Give an example of a condition where primary hypogonadism occurs

A

Premature ovarian failure

15
Q

What happens in premature ovarian failure?

A

Loss of ovarian function causes amenorrhoea, low oestrogen and elevated gonadotrophins

16
Q

What is idiopathic hypogonadotrophic hypogonadism?

A

Absent/delayed sexual development assoc. with low levels of gonadotrophins in the absence of anatomical/functional defect in the H-P-gonadal axis

17
Q

Which syndrome is like idiopathic hypogonadotrophic hypogonadism but includes anosmia (inability to smell)?

A

Kalmann’s syndrome

18
Q

What is the major defect/identified cause of idiopathic hypogonadotrophic hypogonadism?

A

Mutated GnRH receptor (thus inability to sense GnRH from hypothalamus)

19
Q

What is the function of kisspeptin?

A

Regulates GnRH secretion and thus puberty

Regulates fertility

20
Q

What is Kallman’s syndrome?

A

Genetic disorder of loss of GnRH secretion characterised by anosmia and hyposmia

21
Q

Males are more affected by Kallman’s syndrome. True/False?

A

True

4:1

22
Q

What causes hirsutism?

A

Excess androgen at the hair follicle

23
Q

What is the most common cause of hirsutism?

A

Polycystic ovarian syndrome

24
Q

Which chromosome is missing in Turner syndrome?

A

X

so women only have one X

A

Low testosterone

High FHS/LH

27
Q

Define secondary hypogonadism in males in terms of testosterone and LH/FSH levels

A

Low testosterone

Low FSH/LH
