Антиоксидантная терапия продолжает быть одним из основных методов лечения мужского бесплодия, ассоциированного с высоким уровнем фрагментации ДНК сперматозоидов. Одним из перспективных компонентов антиоксидантной терапии является докозагексаеновая кислота (ДГК). Это вещество обладает не только антиоксидантными, но и противовоспалительными свойствами, что позволяет рассматривать его как перспективный компонент комплексного лечения пациентов с высоким уровнем фрагментации ДНК сперматозоидов на фоне воспалительного процесса в добавочных половых железах.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. У 117 пациентов с мужским бесплодием, ассоциированным с высоким уровнем фрагментации ДНК сперматозоидов, изучены спермограмма, результат MAR-теста, индекс фрагментации ДНК сперматозоидов, степень криотолерантности. Пациенты были распределены по 2 группам: с высоким (&gt;1 млн / мл) и низким (&lt;1 млн / мл) содержанием лейкоцитов в эякуляте, а далее рандомизированы в 2 подгруппы активного лечения и 2 подгруппы плацебо. Пациенты из подгрупп активного лечения получали по 1470 мг ДГК в сутки в течение 3 мес, пациенты из подгрупп плацебо принимали плацебо по аналогичной схеме. По завершении курса лечения спермиологические исследования проведены повторно.</p></sec><sec><title>Результаты</title><p>Результаты. После лечения в подгруппе с высоким содержанием лейкоцитов в эякуляте наблюдалось увеличение доли подвижных сперматозоидов (42 % (25–61 %) против 25  (15–47 %), p &lt;0,05), жизнеспособных сперматозоидов (73 % (63–81 %) против 41 % (35–64 %), p &lt;0,05), снижение индекса фрагментации ДНК сперматозоидов (21 % (12–28 %) против 33 % (25–39 %), p &lt;0,05) и концентрации лейкоцитов в семенной жидкости (1 млн /мл (0,7–1,7 млн / мл) против 1,5 млн / мл (1,1–2,1 млн / мл), p &lt;0,05). Увеличение доли подвижных сперматозоидов (15 % (8–19 %) против 8 % (5–11 %), p &lt;0,05) и жизнеспособных сперматозоидов (37 % (25–46 %) против 24 % (17–40 %), p &lt;0,05) также зарегистрировано после теста на криотолерантность. В подгруппе с низким содержанием лейкоцитов в эякуляте отмечено увеличение доли подвижных сперматозоидов (43 % (27–63 %) против 34 % (21–54 %), p &lt;0,05), жизнеспособных сперматозоидов (77 % (66–85 %) против 65 % (54,5–76,0 %), p &lt;0,05) и снижение индекса фрагментации ДНК сперматозоидов (9 % (5,5–20,0 %) против 25 % (18–33 %), p &lt;0,05). Наблюдалось увеличение доли подвижных сперматозоидов (17 % (10–23 %) против 6 % (5,0–10,5 %), p &lt;0,05) и жизнеспособных сперматозоидов (41 % (32,5–53,0 %) против 37 % (30–49 %), p &lt;0,05) после теста на криотолерантность.</p></sec><sec><title>Заключение</title><p>Заключение. ДГК способствует повышению подвижности, жизнеспособности сперматозоидов, снижению уровня фрагментации ДНК сперматозоидов и увеличению их криотолерантности вне зависимости от наличия воспалительного процесса в добавочных половых железах.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Antioxidant supplementation therapy continues to be the main treatment for male infertility associated with high level of sperm DNA damage. Docosahexaenoic acid (DHA) is one of the most promising components of antioxidant supplementation therapy. It also has anti-inflammatory properties that makes it interesting for treatment of patients with high level of sperm DNA damage and inflammation in male accessory glands.</p></sec><sec><title>Materials and methods</title><p>Materials and methods.One hundred and seventeen (117) infertile patients with high level of sperm DNA damage were recruited for this randomized, double blind, placebo-controlled study. Semen analysis, MAR-test, SCD test and sperm cryotolerance test were performed to all patients. Subjects were divided into 2 groups with high (&gt;1 mln / ml) and low (&lt;1 mln / ml) semen leucocyte concertation and then randomized into 2 subgroups of active treatment and 2 placebo subgroups. The active treatment subgroups received 1470 mg / day of DHA for 3 months. The placebo group received placebo for the same period. Laboratory tests were repeated after the treatment course had been finished.</p></sec><sec><title>Results</title><p>Results. Statistically significant increase in motility (42 % (25–61 %) vs 25 % (15–47 %), p &lt;0.05), vitality (73 % (63–81 %) vs 41 % (35–64 %), p &lt;0.05), decrease in sperm DNA fragmentation level (21 % (12–28 %) vs 33 % (25–39 %), p &lt;0.05) and leucocyte concentration (1 million / ml (0.7–1.7 million / ml) vs 1,5 million / ml (1.1–2.1 million / ml), p &lt;0.05) were observed in the subgroup with male accessory glands inflammation after treatment. Motility (15 % (8–19 %) vs 8 % (5–11 %), p &lt;0.05) and vitality (37 % (25–46 %) vs 24 % (17–40 %), p &lt;0.05) in this subgroup after a sperm cryotolerance test increased as well. In the subgroup with low semen leucocyte concertation statistically significant increase in motility (43 % (27–63 %) vs 34 % (21–54 %), p &lt;0.05), vitality (77 % (66–85 %) vs 65 % (54.5–76.0 %), p &lt;0.05) and decrease of sperm DNA fragmentation level (9 % (5.5–20.0 %) vs 25 % (18–33 %), p &lt;0.05) were observed. DHA supplementation also resulted in statistically significant increase in motility (17 % (10–23 %) vs 6 % (5.0–10.5 %), p &lt;0.05) and vitality (41 % (32.5–53.0 %) vs 37 % (30–49 %), p &lt;0.05) after a sperm cryotolerance test in that subgroup.</p></sec><sec><title>Conclusion</title><p>Conclusion. DHA supplementation therapy increases motility, vitality, sperm cryotolerance and decreases sperm DNA fragmentation regardless of the presence of an inflammatory process in male accessory glands.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>докозагексаеновая кислота</kwd><kwd>мужское бесплодие</kwd><kwd>фрагментация ДНК сперматозоидов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>docosahexaenoic acid</kwd><kwd>male infertility</kwd><kwd>DNA fragmentation level</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">Jungwirth А., Diemer T., Kopa Z. et al.
