Extracellular vesicles (EVs) are lipid bilayer-bound particles released from cells that cannot replicate on their own, play a crucial role in intercellular communication, and are implicated in various physiological and pathological processes. Within the domain of embryo culture media research, extensive studies have been conducted to evaluate embryo viability by analyzing spent culture medium. Advanced methodologies such as metabolomic profiling, proteomic and genomic analyses, transcriptomic profiling, non-coding RNA assessments, and oxidative status measurements have been employed to further understand the molecular characteristics of embryos and improve selection criteria for successful implantation. In the field of EVs, only a limited number of studies have been conducted on embryo-conditioned medium, indicating a significant gap in knowledge regarding the potential role of EVs in embryo development and implantation. Therefore, this review aims to evaluate current research findings on EVs enriched from animal and human embryo spent medium. By unraveling the potential link between embryo-derived EVs and embryo selection in clinical settings, such research might enhance embryo-selection methods in assisted reproductive technologies, eventually increasing the success rates of fertility treatments and advancing our understanding of mechanisms underlying successful embryo development and implantation in humans.
