| description | To improve the quality of frozen spermatozoa of Yunnan semi-fine wool sheep, the protective effect of trehalose and sucrose on frozen ram spermatozoa during a non-mating season was evaluated and compared in this study. Briefly, following collection by electric stimulation, equilibration
at 5°C following dilution with the freezing extender, and prefreezing in liquid nitrogen vapor, the ram spermatozoa were frozen in liquid nitrogen. After thawing, viability, motility, acrosome status, membrane integrity, and phosphatidylserine (PS) distribution was determined using a computer-assisted
spermatozoa analysis system and flow cytometry. The data indicated disaccharide can improve the quality of frozen ram spermatozoa. With a trehalose concentration of 100mM, the post-thaw viability and motility (80.56%±6.89% and 46.07%±5.84%) of ram spermatozoa were significantly
more than those of ram spermatozoa frozen with no disaccharide (65.46%±18.96% and 34.62%±9.32%, P0.05). Compared
with sucrose, trehalose can significantly increase the motility of frozen ram spermatozoa (P |

with sucrose, trehalose can significantly increase the motility of frozen ram spermatozoa (P<0.05). In addition, addition of trehalose or sucrose can efficiently protect the acrosome of frozen spermatozoa. Moreover, when the concentration of trehalose or sucrose was 100mM, the protective
effect of trehalose or sucrose on the membrane integrity and PS distribution was significantly higher than that of the control group (P<0.05). However, the protective effect of trehalose on viability, moving velocity, acrosome status, membrane integrity, and PS distribution of frozen

respect to viability, motility, and linear velocity. Moreover, presence of disaccharide can protect acrosome and membrane of frozen sheep spermatozoa.</description><identifier>ISSN: 0143-2044</identifier><identifier>PMID: 22987242</identifier><language>eng</language><publisher>Lewes: Cryoletters</publisher><subject>Acrosome - metabolism ; Animal productions ; Animals ; Biological and medical sciences ; Cell Membrane - metabolism ; Cell Survival ; Cryopreservation ; Cryoprotective Agents - metabolism ; Freezing ; Fundamental and applied biological sciences.
