Согласно результатам немногочисленных исследований белок эритропоэтин принимает участие в регуляции сперматогенеза, воздействуя на синтез гормонов, в частности стероидных. В настоящий момент физиологическое и патогенетическое воздействие эритропоэтина на эякулят человека досконально не изучено. В связи с этим изучение уровня этого белка в эякуляте при заболеваниях органов мужской репродуктивной системы, а также при их отсутствии представляется актуальным.</p><p>Цель исследования – определение концентрации эритропоэтина в эякуляте здоровых мужчин и пациентов с олигоастенозооспермией.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследованы образцы эякулята 52 мужчин репродуктивного возраста с помощью анализатора спермы SQA-V (MES, Израиль). По результатам исследования сформированы 2 группы: в основную вошли 18 мужчин cо сниженной фертильностью, в контрольную группу – 34 мужчины с нормальными показателями спермограммы. Концентрацию эритропоэтина в семенной жидкости определяли путем твердофазного иммуноферментного анализа с использованием тест-системы «Эритропоэтин-ИФА-БЕСТ» (А-8776) («Вектор-Бест», Россия).</p></sec><sec><title>Результаты</title><p>Результаты. Эритропоэтин был обнаружен во всех образцах эякулята, значения варьировали в диапазоне от 9,37 до 193,95 мМЕ / мл и различались в 20,7 раза (р = 0,3). Медиана его концентрации у пациентов основной группы составила 64,49 мМЕ / мл (41,96; 118,16 мМЕ / мл), что в 1,36 раза выше, чем в группе сравнения (47,16 мМЕ / мл (18,15; 90,94 мМЕ / мл). Между концентрацией эритропоэтина и параметрами спермограммы не обнаружено статистически значимых корреляций (r &lt;|0,3|).</p></sec><sec><title>Заключение</title><p>Заключение. При олигоастенозооспермии отмечается тенденция к увеличению содержания эритропоэтина в семенной жидкости, что требует дальнейших исследований с более детальной стратификацией обследованных в зависимости от причин, вызвавших снижение числа сперматозоидов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. There are not enough publications devoted to the study of erythropoietin in human sperm. According to the results of these studies, the erythropoietin takes part in the regulation of spermatogenesis, affecting the synthesis of hormones, in particular steroid ones. Currently, the physiological and pathogenetic effects of erythropoietin on human ejaculate have not been thoroughly studied. In this regard, the study of this protein in the ejaculate in patients with diseases of the male reproductive system, as well as in their absence, is relevant.</p><p>The study objective is to determine the concentration of erythropoietin in ejaculate samples of healthy and men with oligoastenozoospermia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Samples of ejaculate of 52 men of reproductive age were examined. The ejaculate was examined using the SQA-V sperm analyzer (MES, Israel). According to the results of the study, two groups were identified: the main group (n = 18) with reduced fertility and the control group (n = 34) with normal spermogram indicators. In seminal plasma samples, the concentration of erythropoietin was determined by solid-phase enzyme immunoassay using the test system “Erythropoietin-IFA-BEST” (A-8776) (Vector-best LLC, Russia).</p></sec><sec><title>Results</title><p>Results. Erythropoietin was detected in all ejaculate samples, the results ranged from 9.37 to 193.95 mME / ml and varied 20.7 times (p = 0.3). The median concentration in the main group was 64.49 mME / ml (41.96; 118.16 mME / ml) and 1.36 times higher than the results of the comparison group, which were 47.16 mME / ml (18.15; 90.94 mME / ml). No statistically significant regularities were found between the concentration of erythropoietin and the indicators of ejaculate fertility (r &lt;|0,3|).</p></sec><sec><title>Conclusion</title><p>Conclusion. In oligoastenozoospermia, there is a tendency to increase the content of erythropoietin in the seminal plasma, which requires further research, taking into account a more detailed stratification of the groups examined for reasons that caused a decrease in the number of spermatozoa.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эритропоэтин</kwd><kwd>эякулят</kwd><kwd>семенная жидкость</kwd><kwd>олигоастенозооспермия</kwd><kwd>мужское бесплодие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>erythropoietin</kwd><kwd>ejaculate</kwd><kwd>seminal fluid</kwd><kwd>oligoastenozoospermia</kwd><kwd>male infertility</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено на средства гранта Федерации лабораторной медицины по договору от 11 декабря 2019 г.
