Simple ovarian cyst?
Unilocular, more likely to be physiological or benign
Complex ovarian cyst?
Multilocular, more likely to be malignant
Premenopausal women cyst management?
A conservative approach may be taken for younger women (especially if < 35 years) as malignancy is less common. If the cyst is small (e.g. < 5 cm) and reported as ‘simple’ then it is highly likely to be benign. A repeat ultrasound should be arranged for 8-12 weeks and referral considered if it persists.
Postmenopausal ovarian cyst management?
By definition physiological cysts are unlikely –> any postmenopausal woman with an ovarian cyst regardless of nature or size should be referred to gynaecology for assessment
Ovarian hyperstimulation syndrome?
Ovarian hyperstimulation syndrome (OHSS) is a complication seen in some forms of infertility treatment. It is postulated that the presence of multiple luteinized cysts within the ovaries results in high levels of not only oestrogens and progesterone but also vasoactive substances such as vascular endothelial growth factor (VEGF). This results in increased membrane permeability and loss of fluid from the intravascular compartment
When is OHSS more likely to be seen?
With gonadotrophin or hCG treatment. Rarely seen with clomifene therapy?
What % of women having IVF may experience a mild form of OHSS?

Mittelschmerz literally translates to ‘middle pain’ and refers to abdominal pain associated with ovulation. This mid-cyclical pain is experienced by 20% of women and there are several theories as to why it occurs. One explanation is that is occurs due to a leakage of follicular fluid containing prostaglandins at the time of ovulation, which causes the pain. Another explanation is that the growth of the follicle stretches the surface of the ovary, causing pain
Mittelschmertz presentation?
- Sudden onset of pain in iliac fossa which then manifests as generalised pelvic pain
- Typically pain is not severe and varies in duration, lasting from mins to hours
- Self-limiting and resolves within 24 hours of onset

PCOS mushkies?
Polycystic ovarian syndrome (PCOS) is a complex condition of ovarian dysfunction thought to affect between 5-20% of women of reproductive age. Management is complicated and problem based partly because the aetiology of PCOS is not fully understood. Both hyperinsulinaemia and high levels of luteinizing hormone are seen in PCOS and there appears to be some overlap with the metabolic syndrome.

- Spironolactone, flutamide and finasteride under specialist supervision
PCOS infertility management?
- Clomifene first line
- Metformin if obese (can be used in combination)

Clomifene MOA?
Work by occupying hypothalamic oestrogen receptors without activating them. This interferes with the binding of oestradiol and thus prevents negative feedback inhibition of FSH secretion

Excessive pain during menstrual period
Dysmenorrhoea classification?
Primary and secondary
Primary Dysmenorrhoea mushkies?
No underlying pelvic pathology. It affects up to 50% of menstruating women and usually appears within 1-2 years of the menarche. Excessive endometrial prostaglandin production is thought to be partially responsible.

Ectopic pregnancy 3 management strategies?
- Expectant
- Medical
- Surgical
Expectant pregnancy management?
- Size <35mm, unruptured, asymptomatic
- No fetal heartbeat, hCG < 1000
- Compatible if another intrauterine pregnancy
- Expectant management involves closely monitoring the patient over 48 hours and if B-hCG levels rise again or symptoms manifest intervention is performed
Ectopic pregnancy medical management?
- Size <35mm, unruptured, no significant pain
- No fetal heartbeat, hCG <1500
- Not suitable if intrauterine pregnancy

Body temperature rises when in menstrual cycle?
Following ovulation
Menstrual cycle phases?
- Days 1-4 = Menstruation
- Days 5-13 = Follicular (proliferative) phase
- Day 14 = Ovulation
- Days 15-28 = Luteal (secretory) phase
Follicular (proliferative) phase mushkies?
- Number of follicles develop, one will become dominant around mid-follicular phase
- Proliferation of endometrium
- Rise in FSH results in development of follicles which in turn secrete oestradiol. When the egg has matured, it secretes enough oestradiol to trigger the acute release of LH. This in turn leads to ovulation
- Following menstruation the cervical mucus is thick and forms a plug across the external os. Just prior to ovulation the mucus becomes clear, acellular, low viscosity. It also becomes ‘stretchy’ - a quality termed spinnbarkeit
- Basal body temperature falls prior to ovulation due to the influence of oestradiol
Luteal (secretory) phase mushkies?
- Corpus luteum present
- Endometrium changes to secretory lining under influence of progesterone
- Progesterone secreted by corpus luteum rises through the luteal phase. If fertilisation does not occur the corpus luteum will degenerate and progesterone levels fall. Oestradiol levels also rise again during the luteal phase.
- Under influence of progesterone, cervical mucus becomes thick, scant and tacky
- Temperature rises following ovulation in response to higher progesterone levels

Permanent cessation of menstruation. It is caused by the loss of follicular activity. Menopause is a clinical diagnosis usually made in primary care when a woman has not had a period for 12 months.
Menopausal symptoms epidemiology?
Very common and affect roughly 75% of postmenopausal women. Symptoms typically last for 7 years but may resolve quicker and in some cases take much longer.

For vasomotor symptoms, 2-5 years of HRT may be required with regular attempts made to discontinue treatment. Vaginal oestrogen may be required long term. When stopping HRT it is important to tell women that gradually reducing HRT is effective at limiting recurrence only in the short term. In the long term, there is no difference in symptom control.

Atrophic vaginitis?
In post-menopausal women. Presents with vaginal dryness, dyspareunia and occasional spotting. On examination, the vagina may appear pale and dry. Treatment is with vaginal lubricants and moisturisers - if these do not help then topical oestrogen cream can be used.
Endometrial cancer epidemiology?
Classically seen in post-menopausal women but around 25% occur before menopause

Usually caries a good prognosis due to early detection

- Pain is not common and typically signifies extensive disease
- Vaginal discharge is unusual

- Women >=55 years with postmenopausal bleeding –> 2ww
- 1st line Ix = TVUSS, normal endometrial thickness <4mm has a high negative predictive valye
- Hysterosocopy with endometrial biopsy

- Localised disease –> TAH BSO. High risk –> post-op radiotherapy
- Progestogen therapy is sometimes used in frail elderly women not considered suitable for surgery
Protective for endometrial cancer?
COCP and smoking

- Hx of recent amenorrhoea
- Dizziness, fainting or syncope
- Peritoneal bleeding can cause shoulder tip pain and pain on defecation/urination
Ectopic pregnancy examination findings?
- Abdominal tenderness
- Cervical tenderness
- Adnexal mass = dont examine for adnexal mass due to increased risk of rupturing pregnancy, only check for cervical excitation

Points towards a diagnosis of ectopic pregnancy
PMS definition?

1. Mild = usual advice on sleep, exercise, smoking and alcohol, specific advice includes regular, frequent (2–3 hourly), small, balanced meals rich in complex carbohydrates
2. Moderate = COCP e.g. Yasmin® (drospirenone 3 mg and ethinylestradiol 0.030 mg)
3. Severe = SSRI = this may be taken continuously or just during the luteal phase (for example days 15–28 of the menstrual cycle, depending on its length)
