13
Q
What is meant by hypogonadism?
A
Lack of sex hormones, oestrogen and testosterone
The lack of sex hormones, is due to one of two reasons…
1) hypogonadotropic hypogonadism- deficiency in LH and FSH
2) hypergonadotropic hypogonadism- a lack of response to LHand FSH by the gonads
14
Q
What is meant by HYPOgonadotropic hypogonadism?
A
Deficiency in LH and FSH leading to deficiency in the sex hormones
LH and FSH= gonadotropins
No Gonadotropins to stimulate the gonads
15
Q
What are the causes of hypogonadotropic hypogonadism?
A
Hypopituitarism
Damage to hypothalamus or pituitary for example: radiotherapy/surgery for cancer
Significant chronic conditions- temporarily delay puberty (CF, IBD)
Excessive exercise or dieting
Constitutional delay in growth and development
Endocrine disorders- GH deficiency, hypothyroidism, Cushing’s, hyperprolactinaemia, Kallman syndrome
16
Q
What is Kallman syndrome?
A
Genetic condition causing hypogonadotropic hypogonadism, it is associated with anosmia.
17
Q
What is hypergonadotropic hypogonadism?
A
Where the gonads fail to respond to stimulation from the gonadotropins, lack of negative feedback therefore leads to high levels of gonadotropins (hypergonadotropic) and low sex hormones (hypogonadism)
18
Q
What are the causes of hypergonadotropic hypogonadism?
A
Previous damage to the gonads (torsion, cancer, infections like mumps)
Congenital absence of the ovaries
Turners syndrome
19
Q
What is congenital adrenal hyperplasia?
A
Congenital deficiency of 21- hydroxylase enzyme, this causes underproduction of cortisol and aldosterone and overproduction of androgens from birth.
20
Q
How does congenital adrenal hyperplasia present?
A
In severe cases, neonates are unwell shortly after birth, with electrolyte disturbances and hypoglycaemia
In mild cases, female patients can present later in childhood or at puberty, with typical features…
. Facial hair, deep voice, primary amenorrhoea, early puberty, tall for their age
21
Q
What is androgen insensitivity syndrome?
A
Occurs in males, tissues are unable to respond to androgens, have female external genitalia but testes In the abdomen or inguinal canal.
22
Q
What bloods should you do when someone is experiencing amenorrhoea?
A
FBC and ferritin for anaemia
U and E’s for CKD
Anti TTG or anti EMA for coeliac
Hormonal blood tests;
. FSH and LH will be low in hypogonadotropic hypogonadism and high in hypergonadotropic hypogonadism
. TFTs
. Insulin like growth factor (screening for GH deficiency)
. Prolactin (raised in hyperprolactinaemia)
. Testosterone (raised in PCOS, androgen insensitivity syndrome and congenital adrenal hyperplasia)
. Genetic testing- microarray test to look for genetic conditions such as: turners
. Imaging- X-ray of wrist to assess bone age and diagnosis of constitutional delay
Pelvic US to assess ovaries and other pelvic organs
MRI of the brain to look for pituitary pathology
23
Q
How do you treat patients with hypogonadotropic hypogonadism causing primary amenorrhoea ?
A
Pulsatile GnRH
Or replacement sex hormones in the form of COCP if pregnancy not wanted
24
Q
How do you treat a patient with amenorrhoea due to ovarian cause ( PCOS, damage or absence of ovaries?)
A
COCP
25
How does physiological stress lead to secondary amenorrhoea?
The hypothalamus reduces the production of GnRH in response to significant physiological or psychological stress. This leads to hypogonadotropic hypogonadism and amenorrhoea, this is the hypothalamus responding to situations where the body is not fit for pregnancy!
26
What are the pituitary causes of secondary amenorrhoea?
Pituitary tumours- prolactin secreting prolactinom
| Pituitary failure- trauma, radiotherapy, surgery, Sheehan syndrome
27
What is the most common cause of hyperprolactinaemia and why does it cause secondary amenorrhoea?

```
If they are at high risk
Age >45 years
Inter menstrual bleeding
Suspected pathology
Risk factors for endometrial cancer
```
Then you would do history, examination, full blood count, ultrasound scan, hysteroscopy and biopsy
35
What investigations should be done if someone is experiencing heavy menstrual bleeding?
Pelvic examination with a speculum and bimanual should be performed, unless straightforward history of HMB and no risk factors/ symptoms
FBC- iron deficiency anaemia
Hysteroscopy if suspected fibroids, endometrial pathology, persistent intermenstrual bleeding.
USS if large fibroids, obesity, adenomyosis is suspected
Consider: swabs, coagulation screen, ferritin if they are clinically anaemic, TFTs

Tranexamic acid- when there’s no associated pain
Mefenamic acid- when there’s associated pain (NSAID reduces both bleeding and pain)
Management when contraception is acceptable/ wanted...
1) mirena coil
2) COCP
3) cyclical oral progesterone (norethisterone- however this cannot be used long term!)
Progesterone only contraception can be tried- POP, implant, depo injection
37
What are the surgical options for HMB?
Endometrial ablation and hysterectomy.
38
What are fibroids?
Benign tumours of the smooth muscle of the uterus, they are also called uterine leiomyomas, they are oestrogen sensitive.
39
What are the different types of fibroids you can get?
Intramural (within the myometrium)
Subserosal (just below outer layer of uterus)
Submucosal (just below the endometrium)
Pedunculated (on a stalk)
40
What is the presentation of fibroids?
```
Prolonged menstruation
Abdo pain
Bloating, feeling full in the abdomen
Urinary or bowel symptoms
Deep dyspareunia
Reduced fertility .
```
41
What are the investigations of fibroids?
Hysteroscopy- investigation for fibroids presenting with heavy periods
Pelvic ultrasound- bigger fibroids
MRI scanning -may be considered before surgical options

How do you treat fibroids less than 3cm?
This is the same treatment as heavy menstrual bleeding..
. mirena coil (first line)
. Tranexamic acid and NSAIDD
. COCP
. Cyclical oral progestogens
Surgical options for small fibroids include endometrial ablation, resection of submucosal fibroids during hysteroscopy
Hysterectomy
43
How do you treat larger fibroids?
Referral to gynae
Medical management is the same
Surgical options- myomectomy, uterine artery embolisation, hysterectomy
GnRH can be used to reduce the size of fibroids before surgery by reducing the amount of oestrogen needed to maintain fibroids
44
What is the only surgical option known to improve fertility in patients with fibroids?
Myomectomy (removal of the fibroid via. Laparoscopic surgery or laparotomy)
45
What is endometrial ablation?
Used to destroy the endometrium

Urinary outflow obstruction and UTI
Red degeneration of fibroids
Torsion of fibroid
Malignant change to a leiomyosarcoma is very rare
48
What is red degeneration of fibroids?
Refers to ISCHAEMIA, infarction and necrosis of the fibroid due to a disrupted blood supply
Usually occurs in larger fibroids (above 5cm) during the second and third trimester of pregnancy
Fibroids grow rapidly in pregnancy outgrowing it’s blood supply and becoming ischaemic, or the expansion and change in the shape of the uterus causing a kinking in blood vessels.
49

50
What is endometriosis?
Ectopic endometrial tissue outside the uterus
51
What is an endometrioma?
A lump of endometrial tissue outside the uterus.
52
What is an adenomyosis?
Endometrial tissue within the myometrium (Muscle layer of the uterus)
53
What is the main symptom of endometriosis?
Pelvic pain, the cells of the endometrial tissue outside the uterus responds to hormones in the same way as endometrial tissue in the uterus. During menstruation as the endometrial tissue in the uterus shreds its lining and bleeds, the same thing happens to endometrial tissue elsewhere in the body
54
What are some complications of fibroids?
Localised bleeding and inflammation can lead to adhesions, inflammation causes damage and development of tissue that binds the organs together.
Adhesions lead to chronic, no cyclical pain, sharp, stabbing or pulling and associated with nausea.
Reduced fertility
55
What is the presentation of endometriosis?
Cyclical abdominal or pelvic pain
Deep dyspareunia (pain on deep sexual intercourse)
Dysmenorrhoea
Infertility
Cyclical bleeding from other sites- Haematuria, blood in stools
56
How do you diagnose endometriosis?
Pelvic ultrasound may reveal large endometriosis and chocolate cysts but often unremarkable
Laparoscopic surgery is the gold standard way to diagnose abdominal and pelvic endometriosis, definitive diagnose can be established with a biopsy of the lesions during laparoscopy, laparoscopy can allow the surgeon to remove deposits of endometriosis and potentially improve symptoms
57
How would you manage endometriosis?
Pain relief- NSAID and paracetemol
Hormonal options-
COCP (used back without a pill free period if helpful)
POP
Medroxyprogesterone acetate injection (depo provera)
Nexplanon implant
Mirena coil
GnRH agonists
Surgical management- laparoscopic surgery to excise/ablate endometrial tissue and remove adhesions (adhesiolysis)
Hysterectomy (removal of uterus)
58
Give examples of GnRH agonists and side effects of these drugs...

Goserelin, leuprolerin
Inducing the menopause has side effects- hot flushes, night sweats, risk of osteoporosis
59
What is the presentation of adenomyosis?
Dysmenorrhoea, menorrhagia and dyspareunia
On examination, uterus may be tender and enlarged
60
How do you diagnose adenomyosis?

| MRI and transabdominal ultrasound
61
What are the treatments for adenomyosis?
Depends on symptom, age and plans for pregnancy
When the woman doesn’t 2ant contraception- tranexamic acid and mefenamic acid can be used
If contraception is wanted/ accepted...
. Mirena coil (first line)
. COCP
. Cyclical oral progestogens
62
What complications can you have with adenomyosis and pregnancy?

What is postmenopause?
This is from the final menstrual period to 12 months after
65
What is perimenopause?
Time around the menopause, where woman may be experiencing vasomotor symptoms and irregular periods, time leading up to the last menstrual period and the 12 months after.
66
What is premature menopause?
Menopause before the age of 40, it is the result of premature ovarian insufficiency
67
What changes to the sex hormones occur in menopause?
LH and FSH levels aren’t high in response to absence of negative feedback from oestrogen
Oestrogen and progesterone levels are low
68
What are perimenstrual symptoms?
```
These include vaginal atrophy/dryness
Hot flushes
Lack of libido
Emotional liability or low mood
Heavier or lighter periods
Joint pains
Irregular periods
Premenstrual syndrome
```
69

Osteoporosis
Pelvic organ prolapse
Urinary incontinence
70
What investigations could you do for menopause and when would you do them?
FSH levels in blood
In a woman under 40 years with a suspected premature menopause
Woman aged 40-45 with menopausal symptoms or a change in menstrual cycle
71
When can you not give the depot injection?
In over 45 year olds as it reduces bone mineral density.
| It also causes weight gain
72
For how long after the menopause should woman still take contraception for?
If they are under 50 then 2 years after the last menstrual period
If they are over 50 then 1 year after the last menstrual period
73
What is premature ovarian insufficiency?
Menopause before the age of 40
74
For premature ovarian insufficiency, what will hormonal analysis show?
LH and FSH high
| Low oestradiol levels
75
Why is menopause considered hypergonadotropic hypogonadism ?
Under activity of the gonads means there is a lack of negative feedback on the pituitary gland.
76
What are the causes of premature ovarian insufficiency?
Idiopathic
Iatrogenic(chemo, radiotherapy, surgery)
Autoimmune- coeliac disease, adrenal insufficiency, type 1 diabetes or thyroid disease
Genetic- positive FH of turners syndrome

Higher risk of multiple conditions relating to the lack of oestrogen
- cardiovascular disease
- stroke
- osteoporosis
- dementia
- Parkinsonism
80
How do you manage premature ovarian insufficiency?
There is still a risk of pregnancy so contraception still required
HRT to reduce the risks associated with low oestrogen and premature menopause
There are two options for the HRT..
. COCP/ traditional HRT
81
Hormone replacement therapy involves using exogenous oestrogen, what should also be used in women who have an uterus?
Progesterone, this is to prevent endometrial hyperplasia and endometrial cancer, secondary to unopposed oestrogen.

Cyclical HRT with cyclical progesterone and regular breakthrough bleeds.
83
What non hormonal treatments can be used for menopausal symptoms?
Lifestyle changes- improving diet, exercising, smoking cessation, reduced alcohol, reduced caffeine, reduced stress
CBT
SSRI antidepressants
Clonidine
Venlafaxine
GABApentin
84
Clonidine can be used as a non hormonal treatment for menopausal symptoms, what is this and what does it do?
It is an alpha 2 adrenergic and imidazoline receptor agonist in the brain. It reduces heart rate, also used in antihypertensive medication, helpful for vasomotor symptoms, hot flushes.
Dry mouth, headaches, dizziness, fatigue
Sudden withdrawal can result in rapid increase in blood pressure and agitation
85
What are the risks of HRT?
For women over 50:

Patches are more suitable for women with poor control on oral treatment, higher risk of venous thromboembolism, CVD and headaches.
88
When is continuous progesterone used?
When a woman has not had a period in the past
| 24 months if under 50, 12 months is over 50
89
What would giving continuous progesterone cause when a woman is not post menopausal?
Irregular breakthrough bleeding leading to investigations for other underlying causes of bleeding.
90
What are the options for delivering progesterone for endometrial protection?
Oral (tablets)
Transdermal (patches)
Intrauterine system (mirena coil)
Mirena coil is licensed for four years for endometrial protection, after which time it needs replacing.
91
What can occur as a result of mirena coil insertion?
Irregular bleeding and spotting in the first few months after insertion, usually settles with time and women can become amenorrhoeic.
92
What is the difference between progestogens, progesterone, progestin?
Progestogens- chemicals that target and stimulate progesterone receptors
Progesterone- hormone produced naturally in the body

```
100
What can hirsutism be caused by, other than PCOS?
Medications- phenytoin, corticosteroids, testosterone, anabolic steroids
Ovarian or adrenal tumours that secrete androgens
Cushing’s syndrome
Congenital, adrenal hyperplasia
101
What is the pathophysiology behind Insulin resistance in PCOS?
When someone is resistant to insulin, the pancreas has to produce more insulin to get a response from the cells of the body
Insulin promotes the release of androgens from the ovaries and adrenal glands
Higher levels of insulin result in higher levels of androgens (such as testosterone), insulin also suppresses sex hormone binding globulin production by the liver, sex hormone binding globulin usually binds to androgens and suppresses their function. Reduced SHBG further promotes hyperandrogenism in women with PCOS
High insulin levels also contribute to halting the development of follicles in the ovaries, leading to anovulation and multiple partially developed follicles (seen as polycystic ovaries on the scan)
102
What investigations would you use to diagnose PCOS?
```
Testosterone
Sex hormone binding globulin
Leutinizing hormone
FSH
Prolactin (mildly elevated in PCOS)
TSH
```
These exclude other pathologies that have similar presentations.
103
What would the investigation results show in PCOS?
```
Raised LH
Raised LH:FSH ratio
Raised testosterone
Raised insulin
Normal or raised insulin levels
```
104
What is the gold standard investigation for diagnosing PCOS?
Trans vaginal ultrasound
With the diagnostic criteria being...
12 or more developing follicles in one ovary
An ovarian volume of more than 10cm^3
The follicles May be arranged around the periphery of the ovary, giving a string of pearls appearance
105
How do you screen for diabetes in PCOS?
2 hour 75goral glucose tolerance test performed in the morning prior to having breakfast...
Impaired fasting glucose; fasting glucose of 6.1-6.9mmol/l (before the glucose drink)
Impaired glucose tolerance- plasma glucose at 2 hours of 7.8-11.1mmol/l
Diabetes- plasma glucose at 2 hours above 11.1mmol/l
106
What is an ovarian cyst?
Ovarian cyst is a fluid filled sac. Functional ovarian cysts relate to the fluctuating hormones of the menstrual cycle in pre menopausal women, cysts in pre menopausal are very common, they become concerning post menopausal.
107
How do ovarian cysts present?
Most are asymptomatic
Occasionally they can cause non specific symptoms of:
Pelvic pain
Bloating
Fullness in the abdomen
Palpable pelvic mass
Ovarian cysts May present with acute pelvic pain if their is ovarian torsion, haemorrhage, rupture of the cyst.
108
What is a functional cyst?
Relate to the fluctuating hormones of the menstruated cycle
Follicular cysts- represent the developing follicle, when these fail to rupture and release the egg, the cyst can persist.
Corpus luteum cysts- when the corpus luteum fails to break down and instead fills with fluid, they may cause pelvic discomfort, pain, delayed menstruation, often seen in early pregnancy.
109

What is uterine rupture?
Complication of labour where the muscle layer of the uterus (myometrium) ruptures
Incomplete rupture- the myometrium remains intact
Complete- serosa ruptures along with the myometrium and uterus contents are released into the peritoneal cavity
117
What are the risk factors for uterine rupture?
The main risk factor is a previous Caesarean section, the scar on the uterus becomes a point of weakness and may rupture with excessive pressure
Extremely rare to those who are giving birth for the first time
118
What is a uterine inversion?
Rare complication of birth, where the fundus of the uterus drops down through the uterine cavity and into the cervix, turning the uterus inside out.
It is extremely rare.
119
What is a follicular cyst?
They represent the developing follicle, when they fail to rupture and release the egg the cyst will persist. They are harmless and tend to disappear after a few cycles. They have thin walls and no internal structures, giving a reassuring appearance on the ultrasound.
120
What is a corpus luteum cyst?
When the corpus luteum fails to break down and instead fills with fluid (seen in early pregnancy)
121

Women under 40 years with complex ovarian mass, also require tumour markers for a possible germ cell tumour...
. Lactate dehydrogenase
. alpha fetoprotein
. Human chorionic gonadotropin

CA125 is a tumour marker for ovarian cancer, however it is not very specific, what other causes are there for a raised CA-125?
```
Endometriosis
Pregnancy
Fibroids
Adenomyosis
Liver disease
Pelvic infection
```
136
What is the risk of malignancy index for?
This predicts whether an ovarian mass is malignant or not, it takes into account: menopausal status, ultrasound findings, CA125 level
137
How do you treat simple ovarian cysts in premenopausal women?
If less than 5cm then the cyst will always resolve within 3 cycles, they don’t require a follow up scan.
If they are 5-7cm then they require routine referral to gynaecology and yearly ultrasound monitoring
If they are more than 7cm then consider an MRI scan or surgical evaluation as they can be difficult to characterise with ultrasound.
138
How do you treat ovarian cysts in post menopausal women.?
Treatment depends on the CA-125 level
Simple cysts under 5cm with a normal CA-125 level can be monitored with ultrasound every 4-6 months.
If there is a raised CA-125 then they should have a 2 week wait referral.
139
What is ovarian cystectomy?
Persistent or enlarging ovarian cysts may require surgical intervention (with laparoscopy), the affected ovary may aso be removed- oophorectomy.
140
Complications of an ovarian cyst can often present with acute onset pain, what are the main complications of an ovarian cyst?
. Haemorrhage into the cyst
. Torsion
. Rupture (with bleeding into the peritoneum)
141
What is Meigs syndrome?
Involves a triad of...
Ovarian fibroma
Pleural effusion
Ascites
Typically occurs in older women, removal of the tumour results in complete resolution of effusion and ascites.
142
What is ovarian torsion?
Condition where the ovary twists in relation to the surrounding connective tissue, Fallopian tubes and blood supply (adnexa).
143
How does ovarian torsion normally present?
Sudden onset severe unilateral pelvic pain, pain is constant, gets progressively worse and is associated with N and V.
(Usually)
Can be intermittent as the ovarian twists and untwist sand can also be milder
144
What would you find on examination of ovarian torsion?
Localised tenderness, may be a palpable mass, however the absence of a mass does not exclude the diagnosis.
145
How do you investigate an ovarian torsion?
Pelvic ultrasound
Transvaginal is ideal but trans abdo can also be used.
Ultrasound may show whirlpool sign (free fluid in pelvis and oedema of the ovary) Doppler studies may show a lack of blood flow).
Definitive diagnosis is made by laparoscopic surgery
146
How do you manage ovarian torsion?
Depending on the duration and severity, they will require laparoscopic surgery to either....
1) untwist ovary and fix it in place (detorsion)
2) remove the affected ovary (oophorectomy)
Decision is made by visual inspection of the ovary.
147
What are the complications of ovarian torsion?
Delay in treating the torsion can result in loss of functioning of that ovary, however the other ovary can normally fully compensate
Other complications- necrotic ovary May have became infected, develop an abscess leading to sepsis, could rupture leading to peritonitis and adhesions.
