While emerging data suggest that fast vitrification and warming strategies can yield survival and developmental outcomes equivalent to standard protocols - and may offer logistical and physiological advantages - important knowledge gaps remain. Despite these advancements, there is still a strong need for improved permeability parameter estimation, modelling approaches, and prospective clinical studies to rationally optimize vitrification protocols to ensure robust, reproducible outcomes across diverse patient populations.
