Работа выполнена на белых половозрелых лабораторных крысах-самцах Вистар (n=28). Экспериментальные животные были разделены на три группы исследования – контрольную (интактную) и две опытных. Крысы опытных групп в течение двух месяцев ежедневно получали с пищей бисфенол А и триклозан (Sigma-Aldrich, США) в количестве 200 мг/кг. Определяли общее количество сперматозоидов в 1 мл спермы с подсчетом их атипичных форм, а также проводили морфометрические измерения (подсчет численности и площади сечения клеток Лейдига, вычисляли ядерноцитоплазматический индекс (ЯЦИ)). Концентрации бисфенола А и триклозана в яичках измеряли методом газовой хроматографии с масс-спектрометрией. Полученные данные были подвергнуты статистической обработке при помощи программы IBM SPSS Statistics v.21 (IBM Corp., Armonk, NY, США).</p></sec><sec><title>Результаты</title><p>Результаты. Различия в концентрации бисфенола А и триклозана в тканях яичек между группами сравнения были статистически значимыми (р&lt;0.001). Воздействие исследуемых эндокринных дизрапторов приводило к снижению массы яичек. В группе самцов крыс, подвергшихся воздействию бисфенола А, наблюдалось уменьшение снижение общего количества сперматозоидов (р=0.004) с увеличением их атипичных форм (p=0.014) по сравнению с группой интактных животных. Бисфенол А и триклозан вызвали уменьшение численности клеток Лейдига (р=0.001; р=0.001) соотвественно и статистически значимое изменение ЯЦИ. Причем воздействие бисфенола А приводило к снижению ЯЦИ в клетках Лейдига, тогда как влияние триклозана наоборот приводило к увеличению его значения по сравнению с группой интактных животных.</p></sec><sec><title>Заключение</title><p>Заключение. Бисфенол А и триклозан оказывают негативное влияние на морфофункциональное состояние мужских половых желез половозрелых крыс, которое проявляется уменьшением массы яичек, общего количества сперматозоидов на фоне увеличения их атипичных форм, а также снижением численности клеток Лейдига с изменением их ЯЦИ.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to analyze the morphofunctional state of the testes of mature male rats treated with bisphenol A (BPA) and triclosan (TCS).</p><sec><title>Material and methods</title><p>Material and methods. The work was performed on mature male rats (n=28). Experimental animals were divided into three groups – control (intact) and two experimental ones. For two months, rats of the experimental groups received daily bisphenol A and triclosan (Sigma-Aldrich, USA) with food in the amount of 200 mg/kg. The total count of spermatozoa in 1 ml of sperm was determined with the calculation of their atypical forms, and morphometric measurements were made (the total number and area of Leydig cells with their nuclearcytoplasmic ratio). The concentrations of bisphenol A and testicular triclosan were measured by gas chromatography with mass spectrometry (GC-MS). The obtained data was subjected to statistical processing using IBM SPSS Statistics v.21 (IBM Corp., Armonk, NY, USA).</p></sec><sec><title>Results</title><p>Results. Differences between the comparison groups in the concentration of bisphenol A and triclosan in testicular tissues were statistically significant (p &lt;0.001). The endocrine disruptors studied reduced the mass of the testes. A group of male rats exposed to bisphenol A showed a decrease in the total number of spermatozoa (p=0.004) with an increase in their atypical forms (p=0.014) compared with a group of intact animals. Bisphenol A and triclosan caused a decrease in the total number of Leydig cells (p=0.001; p=0.001) respectively, and a statistically significant change in the nuclear-cytoplasmic ratio. Moreover, bisphenol A led to a decrease in the nuclear-cytoplasmic ratio of Leydig cells, whereas triclosal, on the contrary, increased its value in comparison with a group of intact animals.</p></sec><sec><title>Conclusion</title><p>Conclusion. Bisphenol A and triclosan have a negative effect on the morphofunctional state of the male testes of sexually mature rats (decrease in testicular mass, total count of spermatozoa on the background of an increase in their atypical forms, as well as a decrease in the total number of Leydig cells with a change in their nuclear-cytoplasmic ratio).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бесплодие</kwd><kwd>фертильность</kwd><kwd>яички</kwd><kwd>сперматозоиды</kwd><kwd>клетки Лейдига</kwd><kwd>крысы</kwd><kwd>эндокринные дизрапторы</kwd><kwd>бисфенол А</kwd><kwd>триклозан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>infertility</kwd><kwd>fertility</kwd><kwd>testis</kwd><kwd>sperm</kwd><kwd>Leydig cells</kwd><kwd>rats</kwd><kwd>endocrine disruptor</kwd><kwd>bisphenol A</kwd><kwd>triclosan.</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">Луцкий Д.
