This study aimed to explore patients' understanding, attitudes, concerns, psychological well-being, and factors influencing their decisions regarding FP during treatment.</p><p><strong>Methods: </strong>This prospective cohort study involved women aged 18 to 42 diagnosed with non-metastatic breast cancer or lymphoma, treated at the American University of Beirut Medical Center.

Although 87.8% were informed about the fertility risks of their treatment, only 45.4% expressed a desire for FP. Multivariable analysis revealed that parity was significantly associated with fertility concerns (p = 0.019). Decisions favoring FP were significantly influenced by younger age at diagnosis, lower parity, and higher education levels (p = 0.001, p < 0.001, and p = 0.036, respectively). While 56% of patients received FP counseling-mostly from oncologists (83%)-the preference for FP methods varied, with 47% choosing medical approaches and 53% opting for procedural interventions. Despite recognizing the importance of FP, 91% reported that it did not significantly influence their treatment choices. Patients showed greater satisfaction when oncologists discussed fertility-related topics (p < 0.001). Over time, overall FertiQoL scores and DASS-42 scores indicated improved psychological well-being.</p><p><strong>Conclusion: </strong>Our study highlights the complexities of FP decisions among cancer survivors, emphasizing the need for proper counseling to support their quality of life and psychological well-being.</p>","PeriodicalId":15246,"journal":{"name":"Journal of Assisted Reproduction and Genetics","volume":" ","pages":"1401-1414"},"PeriodicalIF":3.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12167191/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143752942","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}
