Linear regression confirmed AMH (B = 1.151, p < 0.001) and age (B =  - 0.139, p = 0.002) as significant predictors of VO. In DuoStim subgroup, DOR patients achieved 3.3 ± 2.1 total VO compared to 6.9 ± 3.3 in cohort 2 (p = 0.001).</p><p><strong>Conclusion: </strong>DOR patients achieve oocyte yields substantially below thresholds associated with reasonable live birth rates, raising concerns regarding FP efficacy. These findings highlight the need for personalized counseling that considers individual patient characteristics and provides evidence-based, realistic expectations for FP. A revision of current AMH thresholds may improve patient selection and cost-effectiveness of FP programs. Younger DOR patients may benefit from oocyte cryopreservation for FP, emphasizing the importance of age stratification.</p>","PeriodicalId":15246,"journal":{"name":"Journal of Assisted Reproduction and Genetics","volume":" ","pages":"865-872"},"PeriodicalIF":2.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12982711/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145833922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
