摘要卵巢低反应（poor ovarian response，POR）极大地限制了辅助生殖技术的成功，准确预测POR的发生、制定个体化治疗方案在临床诊疗中具有重要意义。POR博洛尼亚标准在临床应用中显示出将异质性人群归于一组讨论的不足，POSEIDON（Patient-Oriented Strategies Encompassing Individualized Oocyte Number）团队在此基础上全面考虑年龄、卵巢储备参数及此前对卵巢刺激的反应性三方面因素对辅助生殖结局的影响，提出了更为细致的分类。本文着重探讨POSEIDON分层特点及其临床应用价值，以期为POSEIDON分层在该病的应用提供依据。

abstractsPoor ovarian response (POR) greatly limits the success of assisted reproductive technology (ART), so it is of great significance to accurately predict the occurrence of POR and formulate individualized treatment programs in clinical diagnosis and treatment. The Bologna criteria showed the deficiency in the discussion of grouping heterogeneous population together in clinical application. Based on this, POSEIDON team comprehensively considered the influence of age, ovarian reserve parameters and previous responsiveness to ovarian stimulation on the outcome of ART and proposed a more detailed classification. This paper focuses on the characteristics of POSEIDON stratification and its clinical application value in order to provide reference for the application of POSEIDON stratification in this disease.
