The Rotterdam Criteria are the most recent criteria to diagnose PCOS. They were decided on in Rotterdam during a consensus meeting of the American Society of Reproductive Medicine (ASRM) and the European Society of Human Reproduction and Embryology (ESHRE) in 2003.
The Rotterdam criteria include 3 signs and symptoms that are looked at:
- Infrequent ovulation (oligo-ovulation) or lack or ovulation (anovulation) for an extended period
- Hyperandrogenism (Clinical Hyperandrogenism and/or Biochemical Hyperandrogenism): High levels of androgens in the blood
- Polycystic Ovaries: Many small follicles (12 or more) in the ovaries and/or increased ovarian volume (>10ml)
According to the Rotterdam criteria, 2 of these 3 criteria have to be present for a diagnosis of PCOS.
