Evidence that membrane stress contributes more than lipid peroxidation to sublethal cryodamage in cryopreserved human sperm: glycerol and other polyols as sole cryoprotectant
Human sperm cryopreservation cryoprotectant sublethal cryodamage lipid peroxidation membrane stress

One effect of cryopreservation on human sperm is sublethal cryodamage, in which cell viability post-thaw is lost more rapidly at later times than in fresh cells. We hypothesized two modes of suble...
Chimpanzee（Pan troglodytes）Spermatozoa Osmotic Tolerance and Cryoprotectant Permeability Characteristics
Cryopreservation membrane permeability

Osmotic properties of chimpanzee spermatozoa were studied at 22°C. An electronic particle counter was used to determine the isosmotic cell volume, and the volume response after exposure to four comm...
