Objective : We aimed to explore the multifaceted etiology of recurrent implantation failure (RIF) and evaluate the efficacy of various management strategies, with a focus on refining examination protocols and treatment pathways to improve implantation success rates in patients undergoing in vitro fertilization-embryo transfer. Mechanism : The development of RIF can be attributed to a complex causal network of factors. Chromosomal anomalies, such as aneuploidies, directly impact the genetic viability of embryos. Immune system dysregulation, marked by the presence of autoantibodies, disrupts the normal immunological tolerance required for successful implantation. Endocrine disruptions interfere with the hormonal balance essential for preparing the endometrium for implantation. Anatomical irregularities in the female reproductive tract can physically impede the embryo's ability to implant. Lifestyle factors, including diet, stress, and environmental exposures, influence both male and female reproductive health, affecting gamete quality and implantation potential. These diverse factors interact in a multifaceted manner, making a personalized diagnostic and therapeutic approach essential for addressing the specific causes in each case of RIF. Findings in brief : The review synthesizes current understanding of RIF's etiology, highlighting the need for innovative interventions and adjustments in clinical practice. It emphasizes the significance of a highly personalized approach in managing RIF, incorporating refined examination protocols and tailor-made treatment pathways to address the unique combination of factors present in each case. Conclusions : Effective management of RIF requires innovative interventions and a shift in clinical practice towards personalized care. Identifying gaps in the current understanding of RIF points towards a clear direction for future research, aimed at refining treatment protocols and improving outcomes for patients. This contributes significantly to the broader field of reproductive medicine, aiming to alleviate the clinical and psychological burdens of RIF.
