Diagnosing Polycystic Ovary Syndrome

Reading time: 1 min

The Rotterdam criteria are used to diagnose Polycystic Ovary Syndrome (PCOS). At least 2 of the following 3 criteria must be met:  

  • Excess androgens (clinical and/or blood test). 
  • Ovulatory dysfunction and polycystic ovaries in a gynaecological ultrasound.  
  • Exclusion of other causes that may produce these signs and symptoms, for example congenital adrenal hyperplasia, hyperprolactinaemia, thyroid dysfunction, hypercortisolism and androgen-secreting tumours.  

Because of the great heterogeneity in the presentation of PCOS, once a diagnosis has been established it is essential to determine whether the patient also has obesity, insulin resistance and/or metabolic syndrome, in order to be able to establish which is the best treatment at each stage of her life, and to prevent potential negative outcomes.
