This substance is a structural component of cell membranes, and is responsible for such properties as plasticity and fluidity which are necessary for the implementation of the process of capacitation and acrosome reaction. In addition, docosahexaenoic acid has antioxidant properties. Aim of our study was to assess the effect of dietary supplement docosahexaenoic acid (Brudi PLUS) on such markers of male fertility as the sperm DNA integrity, standard indicators of semen analysis and cryotolerance in infertile men. Materials and methods: a randomized, multicenter, double-blind, placebo-controlled study was conducted. A total of 109 infertile men were recruited to participate in the study. All patients underwent different analyzes, including semen analysis, sperm DNA fragmentation, MAR-test, test ofcryotolerance and electron microscopy analysis ofspermatozoa. In active treatment group patients were prescribed to drug containing 350 mg of docosahexaenoic acid 3 times a day for 90 days. In the control group, patients were administered to a placebo with a similar scheme. All analyzes were repeatedly performed after 3-months of therapy. Results: An increase in the progressive mobility and sperm viability was determined after the test of cryotolerance in the active treatment group. According to electron microscopy analysis of spermatozoa, positive changes were observed in the number ofheads of the normal form with the normal structure of chromatin and acrosome, as well as a decrease in the number of spermatozoa with insufficiently condensed chromatin. Conclusions: the therapy with drug Brudi PLUS in patients with male infertility allows to increase in cryotolerance of sperms as well as decrease in number of sperm ultrastructure defects.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность. Одной из наиболее распространенных жирных кислот, входящих в состав мембран сперматозоидов, является докозагексаеновая кислота. Это вещество является структурным компонентом клеточных мембран, ответственно за такие свойства мембраны сперматозоидов, как пластичность и текучесть, необходимые для реализации процесса капацитации и акросомальной реакции. Докозагексаеновая кислота также обладает антиоксидантными свойствами. Цель: оценить влияние применения биологически активной добавки докозагексаеновой кислоты Бруди ПЛЮС на такие маркеры мужской фертильности, как целостность генетического материала сперматозоидов, стандартные показатели спермограммы и криотолерантность у бесплодных мужчин. Материалы и методы. Рандомизированное многоцентровое двойное слепое плацебо-контролируемое исследование. Для участия в исследовании были набраны 109 пациентов мужского пола с диагнозом «мужское бесплодие». Пациентам выполнялись спермиологические анализы: спермограмма, фрагментация ДНК сперматозоидов, МАР-тест, тест на криотолерантность, ЭМИС. Пациенты из группы активного лечения принимали комплекс, содержавший 350 мг докозагексаеновой кислоты 3 раза в сутки в течение 90 дней. Пациенты из контрольной группы принимали плацебо по аналогичной схеме. По окончании курса лечения спермиологические анализы выполнялись повторно. Результаты. После проведенного лечения в группе активного лечения определялось увеличение прогрессивной подвижности и жизнеспособности сперматозоидов после теста на криотолерантность. По данным ЭМИС, отмечалась положительные изменения в количестве головок нормальной формы с нормальным строением хроматина и акросомы, уменьшение количества сперматозоидов с недостаточно конденсированным незрелым хроматином. Заключение. Лечение с применением Бруди ПЛЮС пациентами с мужским бесплодием приводит к увеличению криотолерантности сперматозоидов, а также к уменьшению количества ультраструктурных нарушений сперматозоидов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>docosahexaenoic acid</kwd><kwd>polyunsaturated fatty acids</kwd><kwd>infertility</kwd><kwd>sperm DNA fragmentation</kwd><kwd>cryotolerance</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>докозагексаеновая кислота</kwd><kwd>полиненасыщенные жирные кислоты</kwd><kwd>бесплодие</kwd><kwd>фрагментация ДНК сперматозоидов</kwd><kwd>криотолерантность</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>WHO Manual for the Standardised Investigation and Diagnosis of the Infertile Couple.
