До карантина у всех участников исследования ПЦР-тест на наличие COVID-19 был отрицательным. При повторном исследовании, проведенном после карантина, при отрицательных результатах ПЦР-теста у 38 из 73 были выявлены Ig G, при отрицательных результатах на IgM к COVID-19. С учетом этого участников исследования разделили на 2 группы. В I группу вошли 35 мужчин, у которых при проведении ИФА-исследовании (иммуноферментный анализ) в крови антитела к COVID-19 не были выявлены. Во II группу вошли 38 мужчин, у которых при повторном исследовании крови были выявлены IgG к COVID-19. Учитывая, что у 4 из них после острого респираторного синдрома при COVID-19, осложненного дыхательной недостаточностью, отмечалась азооспермия, они не рассматривались. Сравнительный анализ показателей спермограммы после карантина показал, что во II группе на фоне общей тенденции к негативации исследуемых параметров спермы, определяющих ее фертильность, достоверно уменьшилось общее количество сперматозоидов в исследуемом материале (P &lt; 0,05). Также достоверно уменьшилось количество прогрессивно-подвижных (P &lt; 0,05) и общее количество подвижных сперматозоидов (P &lt; 0,05) как по отношению к показателям до карантина, так и к результатам исследования спермограммы в I группе, интактной по COVID-19. Таким образом, инфицирование COVID-19 даже при бессимптомном или субклиническом исследовании, не требующем обращения за медицинской помощью, является патогенетически значимым фактором снижения фертильности мужчин. Целесообразно продолжить исследования в этом направлении.</p></abstract><trans-abstract xml:lang="en"><p>A study was carried out on the change in sperm fertility in 73 men included in the in vitro fertilization program with preliminary indicators of normospermia depending on infection during COVID-19 quarantine. Prior to quarantine, all study participants had a PCR test for COVID-19 negative. When a second study was carried out after quarantine, with negative results of the PCR test, Ig G was detected in 38 of 73, with negative results for IgM to COVID-19. With this in mind, the study participants were divided into 2 groups. Group I included 35 men in whom antibodies to COVID-19 were not detected in the blood during the ELISA (enzyme-linked immunosorbent assay) test. Group II consisted of 38 men in whom Ig G to COVID-19 was detected upon repeated blood tests. Considering that 4 of them had azoospermia after acute respiratory syndrome with COVID-19 complicated by respiratory failure, they were not considered. Comparative analysis of spermogram indices after quarantine showed that in group II, against the background of a general tendency towards negative sperm parameters that determine its fertility, the total number of sperm in the test material (P &lt;0.05) significantly decreased, which, in combination with a significant decrease in progressively motile (P &lt;0.05) and the total number of motile spermatozoa (P &lt;0.05), both in relation to the indicators before quarantine and the results of sperm analysis in group I intact according to COVID-19, Thus, infection with COVID-19 even in an asymptomatic or subclinical study that does not require seeking medical attention, it is a pathogenetically significant factor in reducing male fertility. It is advisable to continue research in this direction. Further study of the issue is still required.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фертильность спермы</kwd><kwd>инфицирование</kwd><kwd>субклиническая инфекция</kwd><kwd>COVID-19</kwd><kwd>SARS-COVID-19</kwd><kwd>олигозооспермия</kwd><kwd>астенозооспермия</kwd><kwd>азооспермия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sperm fertility</kwd><kwd>infection</kwd><kwd>subclinical infection</kwd><kwd>COVID-19</kwd><kwd>SARS-COVID-19</kwd><kwd>oligozoospermia</kwd><kwd>asthenozoospermia</kwd><kwd>azoospermia</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">Khalili M.A., Leisegang K., Majzoub A. et al.
