Проанализированы показатели спермограммы и индекс ФДС в 172 образцах эякулята пациентов, обследованных в 2020–2022 гг. На основании данных о наличии или отсутствии инфекции COVID-19 в анамнезе сформированы 3 группы: 1-я группа (n = 16) и 2-я группа (n = 65) – мужчины, перенесшие инфекцию менее чем за 75 дней и более чем за 75 дней до сдачи эякулята соответственно, 3-я группа (сравнения, n = 91) – мужчины, в анамнезе которых отсутствует инфекция. Стандартное спермиологическое исследование выполняли согласно рекомендациям руководства Всемирной организации здравоохранения (2010). ФДС оценивали методом флуоресцентного мечения одно- и двунитевых разрывов ДНК (TUNEL).</p></sec><sec><title>Результаты</title><p>Результаты. Количество сперматозоидов с фрагментированной ДНК (индекс ФДС) в 1-й группе варьировало от 2 до 48 %, во 2-й группе – от 0,9 до 39 %, в 3-й группе (сравнения) – от 1,3 до 52,9 %. Среднее количество гамет с разрывами ДНК в 1-й группе (11,7 ± 3,3 %) было больше, чем во 2-й группе (10,6 ± 0,8 %) и в группе сравнения (10,7 ± 0,8 %), но без статистически значимого различия. Доля пациентов, у которых индекс ФДС превышал референсное значение (≤15 %), в 1, 2 и 3-й группах составила 18,8; 13,8 и 18,7 % соответственно. Количество прогрессивно подвижных (PR) и морфологически нормальных сперматозоидов во 2-й группе было статистически значимо больше, чем в группе сравнения (22,5 ± 1,6 % против 18,0 ± 1,2 % и 5,52 ± 0,47 % против 4,03 ± 0,31 % соответственно).</p></sec><sec><title>Заключение</title><p>Заключение. У мужчин, обследованных в срок менее 75 дней после заболевания COVID-19, содержание сперматозоидов с фрагментированной ДНК выше, чем у пациентов, перенесших COVID-19 более чем за 75 дней до сдачи эякулята, и мужчин, в анамнезе которых отсутствует данная инфекция. В 1-й группе повышенный индекс ФДС отмечали преимущественно у пациентов, перенесших заболевание средней степени тяжести.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To compare sperm parameters and the DNA fragmentation in patients after the COVID-19 infection and in men without a history of infection.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Sperm parameters and DNA fragmentation index were evaluated in 172 patients examined in 2020–2022. Based on the data on COVID-19 infection in the anamnesis, the patient’s cohort was divided into three groups: group 1 (n = 16) and group 2 (n = 65) – patients who had an infectious disease less than 75 days and more than 75 days before the delivery of the ejaculate, respectively, and group 3 (control, n = 91) – men have no coronavirus infection. A standard semen examination was performed according by the WHO guidelines (2010) recommendation. Sperm DNA fragmentation was evaluated by fluorescent labeling of single- and double-strand DNA breaks (TUNEL method).</p></sec><sec><title>Results</title><p>Results. The percentage of spermatozoa with fragmented DNA in group 1 varies from 2 to 48 %, in group 2 – from 0.9 to 39 %, in group 3 (control group) – from 1.3 to 52.9 %. The average number of gametes with DNA breaks in group 1 (11.7 ± 3.3 %) is greater than in group 2 (10.6 ± 0.8 %) and in group 3 (10.7 ± 0.8%), but without a statistically significant differences. The proportions of patients whose DNA fragmentation index exceeds the reference value (≤15 %) in groups 1, 2 and 3 are 18.8; 13.8 and 18.7 %, respectively. The count of progressively motile (PR) and morphologically normal spermatozoa in group 2 is statistically significantly greater than in group 3 (22.5 ± 1.6 % vs 18.0 ± 1.2 % and 5.52 ± 0.47 % vs 4.03 ± 0.31 %, respectively).</p></sec><sec><title>Conclusion</title><p>Conclusion. The content of sperm with fragmented DNA is higher in men examined less than 75 days after COVID-19 disease, than in patients, examined more than 75 days after COVID-19 and in men who have no history of this infection. In group 1 an increased DNA fragmentation index was noted mainly in patients who had suffered from the disease in a moderate form.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>инфекция</kwd><kwd>мужская фертильность</kwd><kwd>сперматозоиды</kwd><kwd>фрагментация ДНК</kwd><kwd>эякулят</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>infection</kwd><kwd>male fertility</kwd><kwd>sperm</kwd><kwd>DNA fragmentation</kwd><kwd>ejaculate</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации.</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the state task of the Ministry of Science and Higher Education of the Russian Federation.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Agarwal А., Said T.M.
