Abstract:
Aim: Cryopreservation of mouse sperm commonly uses raffinose, which is a trisaccharide, plus 3% skim milk. Because of the present lack of knowledge of the effectiveness of any other saccharides, we examined the cryoprotective effects of various saccharides on the viability of mouse sperm from various strains to determine which saccharides are the best cryoprotectants for mouse sperm. Methods: Sperm from the caudae epididymides of mature C57BL/6J mice were frozen with monosaccharides (fructose, glucose, rhamnose, xylose), disaccharides (lactose, maltose, sucrose, trehalose) or trisaccharides (melezitose, raffinose) in a range of concentrations (4–33%). After thawing, the optimal concentration was determined to be the concentration in which there was the highest proportion of motile sperm. In addition, sperm of inbred and hybrid mice were frozen with the saccharides at the optimal concentrations and used for in vitro fertilization. Results: The optimal concentration was 12% for the disaccharides and 18% for the trisaccharides. The fertility of all strains, except C57BL/6J, showed the best cryoprotective effects with maltose, melezitose and raffinose when compared with fresh sperm. Conclusion: Maltose, melezitose and raffinose have the best effects when used as a protectant for cryopreservation of mouse sperm. (Reprod Med Biol 2007; 6: 229–233)
