The aim of this study was to evaluate the physiological status of vitrified\/warmed equine IVM oocytes following vitrification using two temperature\u2010specific equilibration protocols by assessing reactive oxygen species (ROS), intracellular glutathione (GSH) content and mitochondrial oxidative activity and distribution patterns. Oocytes were vitrified after 28\u2009h of IVM either at 25\u00b0C (in VIT25) or at 38.5\u00b0C (in VIT38.5) and cultured for an additional 2\u2009h after warming. No significant differences were detected among groups in ROS levels, GSH content, mitochondrial oxidative activity or distribution patterns (\n p<\/jats:italic>\n \u2009>\u20090.05). These results indicate that the vitrification protocols evaluated did not induce detectable alterations in redox balance or mitochondrial function in equine IVM oocytes. This suggests that vitrified\/warmed oocytes may maintain characteristics compatible with fertilisation and subsequent embryonic development, although their developmental competence was not directly evaluated and warrants further investigation.\n
