Investigation
- History and clinical examination
- Investigations - both biochemical parameters and ovarian imaging
- AE-PCOS Society Criteria 2006
- Clinical and/or biochemical signs of hyperandrogenism
- Ovarian dysfunction (Oligo- anovulation and/or polycystic ovarian morphology)
- Both criteria needed for diagnosis
- Ultrasound – Polycystic ovarian morphology (PCOM): 2 antral follicles (2 – 9 mm in diameter) in either ovary, an ovarian volume of >10 mL in one or both the ovaries
- Hormonal investigations
- Free testosterone – best marker of ovarian androgen production
- Dehydroepiandrosterone sulfate (DHEAS)
- Anti-mullerian hormone (AMH) and 17 –hydroxyprogesterone
- Thyroid function tests – to exclude thyroid abnormality
- Prolactin – to exclude hyperprolactinemia
- Increased LH/FSH ratio
Screening for cardiometabolic risk factors
- Blood pressure
- BMI
- Waist circumference (> 88 cm or 35 inches)
- Lipid profile (Increased total cholesterol, triglycerides and LDL and low levels of HDL) – done every two years, earlier if the woman has gained weight
Screening for Impaired glucose tolerance and Type 2 diabetes mellitus
- Fasting Blood glucose
- 75 Gram GTT – repeated every 1-5 years depending on the patient characteristics
- Glycosylated haemoglobin (HbA1c)
- Glucose-insulin ratio (< 4.5 suggestive of insulin resistance)
