Although in vitro fertilization and embryo transfer with donated eggs enables pregnancy, not a few patients desire pregnancy using their oocytes. However, follicular development is rare and unpredictable in patients with POI. Thus, there is a need for treatments that promote the development of residual follicles and methods to accurately predict infrequent ovulation.</p><p><strong>Methods: </strong>This review discusses the effects of various treatments for obtaining eggs from POI patients. Furthermore, this study focused a potential marker for predicting follicular growth in patients with POI.</p><p><strong>Main findings: </strong>Different treatments such as hormone-replacement therapy, dehydroepiandrosterone supplementation, platelet-rich plasma injection, and in vitro activation have shown varying degrees of effectiveness in retrieving oocytes from patients with POI. To predict follicle development in the cycle, elevated serum estradiol and reduced follicle-stimulating hormone (FSH) levels are important. However, these markers are not always reliable under continuous estradiol-replacement therapy. As a novel marker for predicting follicle growth, serum anti-Müllerian hormone (AMH) levels, measured using the picoAMH enzyme-linked immunosorbent assay, were found to predict follicle growth in patients and the cycle.</p><p><strong>Conclusion: </strong>This review highlights the challenges and available interventions for achieving pregnancy using a patient's oocytes in cases of POI. We believe that a combination of currently available treatments and prediction methods is the best strategy to enable patients with POI to conceive using their own eggs. Although AMH levels may predict follicle growth, further research is necessary to improve the chances of successful follicular development and conception in patients with POI.</p>","PeriodicalId":21116,"journal":{"name":"Reproductive Medicine and Biology","volume":"22 1","pages":"e12556"},"PeriodicalIF":2.7,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10746865/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139032539","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}
