The prevalence of idiopathic male infertility has the highest rate. Oxidative stress, genetic factor, and endocrine disruptors are considered to be the most probable causes for the idiopathic male infertility. In this regard, studying the effect of endocrine disruptors, in particular bisphenol A on male reproductive health, becomes actual and relevant. <bold>Aims</bold>: The aim of the study was to reveal the relationship between the concentration level of bisphenol A (BPA) in seminal fluid and semen quality in men with normo- or pathozoospermia, as well as between the concentration level of bisphenol A and the level of total testosterone and estradiol in plasma. <bold>Materials and methods</bold>: 53 samples of seminal fluid of men with normo- or pathoospermia were studied. In seminal fluid the concentration of bisphenol A was determined by gas chromatography with mass spectrometry (GC-MS). The spermiological analysis was performed according to the WHO recommendations (2010) including the evaluation of sperm count/concentration, motility and morphology, and DNA fragmentation index. In addition, the concentration of total testosterone and estradiol in plasma was determined. The results were statistically processed using the Mann–Whitney U test, the correlation analysis, the paired regression method, and the ROC curves to determine the cut-off point for BPA in the seminal fluid. The results were considered statistically significant at p&lt;0.05.<bold> Results</bold>: In 100% of the ejaculate samples BPA with a median concentration of 0.15 (0.06–0.31) ng/ml was detected. Using the Spearman rank correlation coefficient, statistically significant correlations between the concentration of BPA and the total count (r=-0.330, p=0.016), concentration (r=-0.309; p=0.024), the proportion of progressively motile spermatozoa (r=-0.575; p=0.001), the proportion of spermatozoa with normal morphology (r=-0.397, p=0.003), the degree of sperm DNA fragmentation (r=0.349, p=0.025), and the concentration of total testosterone (r =-0.616; p&lt;0.001) were registered. A statistically significant inverse linear relationship (r=-0.406, p=0.003) and (r =-0.364, p=0.048) was determined by a paired linear regression between the BPA concentration in the seminal fluid and the proportion of progressively motile spermatozoa, and the total testosterone level respectively. To assess the risk of pathozoospermia, the threshold value of seminal BPA concentration was determined using the analysis of ROC-curves; the cut-off point was 0.1025 ng/ml. <bold>Conclusions</bold>: BPA in the seminal fluid influences negatively on the quality of the sperm and suppress the level of total testosterone in plasma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold>. Нарушение репродуктивного здоровья мужчин является одной из актуальных проблем медицины во всем мире. При этом самой частой формой мужского бесплодия является идиопатическое. Среди наиболее вероятных причин идиопатического бесплодия называются оксидативный стресс, генетические факторы, а также эндокринные дизрапторы. В связи с этим становится актуальным изучение влияния эндокринных дизрапторов, в частности бисфенола А, на мужское репродуктивное здоровье. <bold>Цель исследования</bold> — установить связь между уровнем концентрации бисфенола А в семенной жидкости и качеством эякулята у мужчин с нормо- и патозооспермией, а также с уровнем общего тестостерона и эстрадиола плазмы крови. <bold>Методы</bold>. Исследовано 53 образца семенной жидкости мужчин с нормо- и патозооспермией. В семенной жидкости определялась концентрация бисфенола А методом газовой хроматографии с масс-спектрометрией (GC-MS). Спермиологическое исследование проводилось согласно рекомендациям ВОЗ (2010) с учетом оценки количества сперматозоидов, их подвижности и морфологии, а также индекса фрагментации ДНК сперматозоидов. Кроме того, определялся уровень концентрации общего тестостерона и эстрадиола в плазме крови. Полученные результаты были подвергнуты статистической обработке с использованием U-критерия Манна–Уитни, корреляционного анализа, метода парной регрессии, а также ROC-анализа с целью определения точки сut-off для бисфенола А в семенной жидкости. Результаты считались статистически значимыми при р&lt;0,05. <bold>Результаты</bold>. В 100% образцов эякулята был обнаружен бисфенол А со срединной концентрацией 0,15 (0,06–0,31) нг/мл. С помощью коэффициента ранговой корреляции Спирмена были обнаружены статистически значимые корреляционные связи между концентрацией бисфенола А и общим количеством сперматозоидов (r=-0,330; p=0,016), концентрацией (r=-0,309; p=0,024), и долей прогрессивно подвижных сперматозоидов (r=-0,575; p&lt;0,001), долей сперматозоидов с нормальной морфологией (r=-0,397; р=0,003), степенью фрагментации ДНК сперматозоидов (r=0,349; р=0,025) и концентрацией общего тестостерона крови (r=-0,616; р&lt;0,001). Методом парной линейной регрессии между концентрацией бисфенола А в семенной жидкости и долей прогрессивно подвижных сперматозоидов, а также уровнем общего тестостерона крови была определена статистически значимая обратная линейная зависимость — r=-0,406; р=0,003 и r=-0,364; р=0,048 соответственно. С помощью анализа ROC-кривых для оценки риска патозооспермии определено пороговое значение концентрации бисфенола А эякулята в точке cut-off — 0,1025 нг/мл. <bold>Заключение</bold>. Бисфенол А в семенной жидкости может вносить негативный вклад в качество эякулята и подавлять уровень общего тестостерона крови . </p></trans-abstract><kwd-group xml:lang="en"><kwd>infertility</kwd><kwd>semen quality</kwd><kwd>endocrine disruptors</kwd><kwd>bisphenol A</kwd><kwd>testosterone</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бесплодие</kwd><kwd>качество эякулята</kwd><kwd>эндокринные дизрапторы</kwd><kwd>бисфенол А</kwd><kwd>тестостерон</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Zolkina I.
