We aimed to test the common belief, that as the sperm cell is the smallest cell in an organism and, therefore, it contains a small amount of intracellular water, the intracellular ice should not strongly affect the sperm cell during the cryopreservation. To investigate the effect of intracellular ice, we developed a novel approach of ram spermatozoa ultra-rapid freezing with the inhibition of the growth of extracellular ice crystals during freezing. In our approach, ram sperm was supplemented with cell-impermeable synthetic ice blocker 1,4-Cyclohexanediol, leaving a sample unsupplemented as a control.
