   <abstract xml:lang="ru">
    <p>Криоконсервация мужских половых гамет является одним из важнейших методов вспомогательных репродуктивных технологий, позволяющим сохранить гаметы перед началом лечения, способного повлиять на фертильность мужчины. Однако, оплодотворяющая способность сперматозоидов после криоконсервации уменьшается в среднем на 30-70 %, что обуславливает актуальность поиска новых веществ, обладающих криопротекторными свойствами. В работе был предложен протокол приготовления эмульсии яичного желтка и схема модификации ею криопротектанта. Данная модификация криопротектора показала положительное влияние на сохранность фертильных сперматозоидов: увеличила число гамет с нормальными типами подвижности после криоконсервации на 20 %, а также уменьшила степень морфологических дефектов. Эмульсия, приготовленная по разработанному протоколу, была проверена на цитотксичность и сравнивалась с коммерческим криопротектантом, содержащим яичный желток.</p>

    <p>Cryopreservation of human gametes is one of the most important methods of IVF allowing to save functional gametes prior to the treatment which might threaten male fertility. However, fertilizing capacity of spermatozoa after cryopreservation decreases by 30-70 % on average, explaining the relevance of search for new substances and protocols possessing improved cryoprotective properties. In this work we suggested modification of cryoprotectant by addition of specifically prepared egg yolk emulsion. Such modification showed positive influence on safety of fertile spermatozoa, - increasing the mean number of normal motile gametes after cryopreservation by 20 % and decreasing morphological defectiveness. The emulsion was tested for cytotoxicity and compared with commercially available cryoprotectant containing egg yolk.</p>
