As a result, infertility, interruption to childbearing, or inability to conceive can have profound negative mental health impacts for this population, who often report fertility-related distress, depression, anxiety, and reproductive concerns. Most patients who preserve fertility report feeling confident in their decision, even if preservation outcomes are not favorable, whereas patients who do not preserve fertility report higher rates of decisional regret. Integrating mental health into clinical models of oncofertility care delivery is critical to ensure that patients with new, persistent, or worsening psychological symptoms are captured and appropriately cared for.

Gonadotoxic treatments --such as chemotherapy, radiation, and surgery --can significantly impair reproductive potential, yet access to fertility preservation remains inconsistent. This review examines the clinical and logistical considerations involved in implementing fertility preservation for cancer patients, including patient selection, preservation methods, timing, and barriers to care. A systematic literature search was conducted using PubMed, ScienceDirect, and Embase from inception to February 2025, including original research, observational, and qualitative studies. Despite guidelines from ASCO and ASRM recommending early fertility preservation consultation, referral rates remain low due to provider, institutional, and financial barriers. The choice and feasibility of fertility preservation depend on factors such as cancer type, treatment urgency, patient age, and overall medical condition. Oocyte and embryo cryopreservation are standard options, while ovarian tissue cryopreservation is suitable for prepubertal patients or those requiring urgent treatment. Fertility preservation requires timely, multidisciplinary coordination, with individualized patient assessment and early referral essential for optimizing outcomes. Addressing systemic, educational, and financial obstacles is crucial to ensuring equitable access and maintaining future parenthood opportunities as a priority in oncologic care planning.</div></div>","PeriodicalId":12275,"journal":{"name":"Fertility and sterility","volume":"124 4","pages":"Pages 585-592"},"PeriodicalIF":7.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144923876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key limitations of nonrandomized studies of interventions include susceptibility to confounding and selection bias, which require meticulous study design and advanced analytical techniques to address. Recent innovations, such as target trial emulation studies, have enhanced the validity of causal inferences based on nonrandomized studies of interventions. This article outlines 7 recommendations to improve the credibility of nonrandomized studies of interventions in ART research: clearly define research questions with precise estimands; design nonrandomized studies of interventions as emulated trials; use directed acyclic graphs to clarify causal assumptions; preregister study protocols; separate data analysis from study planning; incorporate negative controls to detect biases; and use appropriate analytical methods to account for confounding and selection bias.</div></div><div><h3>Conclusion</h3><div>Integrating evidence from RCTs and well-conducted nonrandomized studies of interventions enhances clinical decision making in fertility treatment research.
