Трегалоза в составе консерванта значительно снижала относительное количество сперматозоидов с поврежденными мембранами после 14 суток хранения по сравнению с консервантом без трегалозы (1,4±0,4% и 8,2±1,2% соответственно; p=0,00; N=16). В то же время, для обоих консервантов не установлены различия по способности сперматозоидов восстанавливать подвижность после хранения (p=0,57; N=16), а также по фрагментации хроматина (p=0,69; N=12). Эти наблюдения могут быть полезными при оптимизации методики гипотермического хранения спермы человека в репродуктивной медицине.</p></abstract><trans-abstract xml:lang="en"><p>This work presents data on hypothermic storage without freezing of epididymal sperm of C57BL/6 mice in two electrolyte-free preservative buffers based on glucose and albumin, one of them supplied with 50 mM trehalose. The adding of trehalose in preservative buffer brought down significantly percentage of spermatozoa with damaged membrane after 14 days of storage as compared to solution without trehalose (1.4±0.4% vs 8.2±1.2%; p=0.00; N=16). At the same time, there were no differences between two buffers in the ability of sperm to regain motility after storage (p=0.57; N=16) as well in the chromatin fragmentation (p=0.69; N=12). Our findings might be useful for optimization of hypothermic storage protocol for human sperm in reproductive medicine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипотермическое хранение спермы</kwd><kwd>безэлектролитная среда</kwd><kwd>трегалоза</kwd><kwd>hypothermic sperm storage</kwd><kwd>electrolyte-free buffer</kwd><kwd>trehalose</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Исаев Д.А., Заева В.В., Бакурадзе Р.В. и др.
