Influence of Three Combinations of Cryoprotectants and Two Warming Temperatures on Cellular Morphology, Morphometry and Mitochondrial Activity of Vitrified Canine Testicles

open access: yesReproduction in Domestic Animals, Volume 60, Issue 5, May 2025.
ABSTRACT High concentrations of cryoprotectants required for testicular vitrification result in a toxic environment for cells. To mitigate this issue, a suitable alternative is to combine cryoprotectants. The temperature for warming a vitrified sample is also important to assure cell viability.
