title: The Bologna criteria for the definition of poor ovarian responders: is there a need for revision?
abstract: The Bologna criteria were published by the European Society of Human Reproduction and Embryology (ESHRE) in 2011 to help address the lack of a clear definition of poor ovarian responders. Since its publication, aspects of the criteria have been cited several times, whilst others have been criticized. In this debate, we re-examine the criteria (which address age, the number of oocytes retrieved and the results of ovarian reserve tests) following new evidence produced and we analyse the criticism received in an attempt to determine if revisions are needed.
