Los posibles papeles de las vesículas extracelulares en la reproducción de animales salvajes

Wild animals exhibit diverse reproductive processes crucial for species survival, and recent research has unveiled the integral role of extracellular vesicles (EVs) in orchestrating various aspects of their reproductive survival. This chapter explores the multifaceted involvement of EVs in wild animals' reproduction, encompassing oocyte maturation, spermatogenesis, sperm cryopreservation, preimplantation embryo development, embryo implantation, and the transmission of EVs from male to female. EVs play a pivotal role in oocyte maturation, influencing crucial molecular environments for successful fertilization. Furthermore, the intersection of EVs and spermatogenesis sheds light on how these vesicles contribute to the intricate process of sperm development. Additionally, we explain the impact of EVs on sperm cryopreservation, offering insights into potential advancements in assisted reproductive technologies of wild animal species. Furthermore, the involvement of EVs in preimplantation embryos elucidates their role in shaping the early stages of embryonic development. Notably, the transmission of EVs from male to female is also highlighted, revealing a potential communication channel crucial for successful reproduction. The impact of EVs on improving assisted reproductive technology (ART) outcomes is also explained, showcasing their potential as a tool for enhancing fertility treatments. Additionally, the role of EVs in infertility is explored, providing valuable insights into potential diagnostic and therapeutic avenues. Overall, this chapter underscores the intricate interplay between EVs and various facets of wild animals' reproductive biology. The future implications of understanding EVs in wild animals' reproduction emphasize the need for continued research and innovation in this field.
