A couple's lifestyle, age and environmental exposures can interfere with reproductive health. The scientific field tries to understand the various processes how male and female factors may affect fertility, but translation to the clinic is limited. I here emphasize potential reasons for failure in optimal treatment planning and especially why current prediction modelling falls short. First, Assisted Reproductive Technology (ART) has become a mainstream solution for couples experiencing infertility, while potential causes of infertility remain unexplored or undetermined. For instance, the role of men is generally left out of preconceptional testing and care. Second, regularly used statistical or computational methods to estimate pregnancy outcomes miss important biological and environmental factors, including features from the male side (e.g., age, smoking, obesity status, alcohol use and occupation), as well as genetic and epigenetic characteristics. I suggest using an integrated approach of biostatistics and machine learning methods to improve diagnostics and prediction modelling in the fertility clinic. The novelty of this concept includes the use of empirically collected information on the sperm epigenome combined with readily available data from medical records from both partners and lifestyle factors. As the reproductive field needs well-designed models at different levels, derivatives are needed. The objectives of patients, clinicians, and embryologists differ slightly, and mathematical models need to be adapted accordingly. A multidisciplinary approach where patients are seen by both, clinicians and biomedically skilled counsellors, could help provide evidence-based assistance to improve pregnancy success. Next, when it concerns factors that may change the ability to produce optimal embryos in ART, the embryologist would benefit from a personalized prediction model, including medical history of the patient as well as genetic and epigenetic data from easily accessible germ cells, such as sperm.</p>","PeriodicalId":73103,"journal":{"name":"Frontiers in reproductive health","volume":"7 ","pages":"1506312"},"PeriodicalIF":2.3,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11903727/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite growing utilization of IVF technologies, there is little known about the experiences of those accessing or undergoing IVF, particularly among adults in the U.S. The aims of this review are to (1) explore how economic, emotional and physical health, and interpersonal relationships impact and are impacted by accessing or undergoing IVF, and (2) understand the role of healthcare providers and the healthcare system.</p><p><strong>Methods: </strong>A narrative review was conducted to summarize the current literature and provide insight into potential channels for care improvement. Eligible studies were published in English from 2013 to 2024 which qualitatively evaluated experiences of individuals and couples accessing or undergoing IVF. Peer-reviewed publications were identified from three electronic bibliographic databases. Methodologic rigor was assessed by two reviewers who also abstracted data on the study's characteristics as they pertained to four domains: health systems, economic, interpersonal, and physical and emotional health. Among the 32 papers retrieved for review, 22 met inclusion criteria and were retained for analysis.</p><p><strong>Results: </strong>The available literature suggests accessing and undergoing IVF can be positively and negatively influenced by health systems, economic, interpersonal, and physical and emotional health factors. Often an individual or couple experiences multiple factors that compound to create a complex situation. Health systems-related factors included physician interaction and challenges with information volume and processing. Economic challenges primarily pertained to financing IVF and navigating insurance coverage. Interpersonal factors related to changes in relationships with partners, family members, and friends due to IVF. Physical health concerns (e.g., pain) and emotional health concerns (e.g., sadness, stress) were also noted by all included papers.</p><p><strong>Conclusions: </strong>Efforts to improve care experiences of adults accessing or undergoing IVF are urgently needed. The evidence base points to a need for provider sensitivity trainings, clinic-based intervention, and community education in both physical and virtual spaces.</p>","PeriodicalId":73103,"journal":{"name":"Frontiers in reproductive health","volume":"7 ","pages":"1490917"},"PeriodicalIF":2.3,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11865040/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
