Summary

The effect of the antifreeze peptide type 1 from winter flounder, Pseudopleuronectes americanus, and the antifreeze glycoprotein from Antarctic cod, Dissostichus mawsoni, was assessed on the motility of ram spermatozoa after chilling (5 deg C) and after freeze-thawing. The effect was not concentration dependent nor did it depend on which antifreeze protein was added. However, due to the cytotoxicity during the chilling stage, only antifreeze peptide at a concentration of 10 microgram/milliter increased the percentage of motile spermatozoa significantly following freezing and thawing over that of the control (P lower than 0.05). Possible mechanisms are proposed.
