Abstract

Purpose: The ESHRE Working Group on Poor Ovarian Response defined a set of variables to define poor responders, named as the Bologna Criteria, but several concerns have been raised regarding their applicability and prognostic significance. In order to evaluate the clinical relevance of the criteria, we retrospectively analyzed the ovarian response and live birth rates in women who had consecutive IVF attempts, according to their fulfillment of the criteria. Methods: The study group comprised 1153 and 288 women who had two and three consecutive ovarian stimulation (OS) cycles between May 2010 and January 2017, respectively. We compared the ovarian response and live birth rates in subsequent IVF attempts of Bologna criteria-defined poor responder women and women who did not fulfill the Bologna criteria. Results: Women who fulfilled the criteria achieved higher rates of poor ovarian response (76.2% vs 14.3% and 60.3% vs 13.4%) and lower live birth rates (14.6% vs 33.3% and 12.9% vs 34.3%) in their second and third OS cycles, respectively (both p<0.001) compared to women who did not fulfill the criteria. The former group also had lower number of oocytes and lower likelihood of having embryo transfer in their subsequent OS cycles. The criteria were able to predict both ovarian response and clinical outcome in the subsequent cycle in <40-year-old women, whereas they were predictive only for the ovarian response but not for the clinical outcome in women over 40years of age, who exhibited very low live birth rates regardless of the fulfillment of the criteria. Conclusions: The results of this study show that the Bologna criteria are clinically relevant in terms of prediction of ovarian response and clinical outcome in subsequent OS cycles.
