摘要
To the Editor:The conflicting definition of poor ovarian response has complicated the comparison of proposed treatments.The Patient Oriented Strategies Encompassing Individualized Oocyte Number(POSEIDON)classification[1]was formulated to guide individual ovarian response management through detailed stratification.POSEIDON groups 3 and 4 were defined as patients with low anti-Müllerian hormone(AMH;<1.2 ng/mL)and/or low antral follicle count(AFC;<5).
