This comprehensive review delves into the evolving landscape of assisted reproductive technologies (ARTs) in bovine species, particularly focusing on the pivotal roles of semen additives in the cryopreservation of buffalo and cattle semen. In developing nations, where ARTs are still emerging, these techniques significantly influence bovine reproductive strategies. In contrast, developed regions have embraced them as primary approaches for dairy buffalo and cattle breeding. Semen cryopreservation, while offering advantages like extended storage and genetic propagation, also presents challenges. These include diminished sperm quality due to reactive oxygen species (ROS) production, alterations in sperm structure, and temperature fluctuations. Further, the effect of cryopreservation differs between cattle and buffaloes, with the latter exhibiting poorer semen viability and fertility due to inherent lipid composition susceptibilities. The generation and implications of ROS, especially hydrogen peroxide, contribute significantly to sperm DNA damage and functional impairments. To counteract these challenges, research has intensified on semen additives, aiming to bolster semen quality and protect against oxidative stress-induced damage. As the field advances, the review emphasizes the need for optimized cryopreservation techniques and tailored antioxidant strategies to harness the full potential of ARTs in bovine breeding programs.
