   <abstract xml:lang="ru">
    <p>Дихлордифенилтрихлорэтан (ДДТ) является наиболее распространенным системным поллютантом и эндокринным дисраптором. Проведено исследование влияния пренатального и постнатального воздействия ДДТ в низких дозах, соответствующих потреблению ДДТ человеком с продуктами питания с учетом максимально допустимых уровней содержания ДДТ в пищевой продукции на параметры синтеза мужских половых гормонов в гонадах и надпочечниках у половозрелых самцов крыс. Установлено, что после достижения половой зрелости у самцов отмечается пониженный уровень общего тестостерона и андростендиона в сыворотке крови. Исследование механизмов снижения синтеза половых гормонов показало, что у крыс, подвергавшихся воздействию низких доз ДДТ в развитии, отмечается высокий уровень прогестерона и пониженный уровень 17-оксипрогестерона, являющегося непосредственным предшественником синтеза андрогенов. Таким образом, воздействие низких доз ДДТ на развивающийся организм не влияло на синтез прогестерона, но вызывало снижение его гидроксилирования, что обусловливало накопление прогестерона в системном кровотоке и приводило к уменьшению продукции мужских половых гормонов как в семенниках, так и в надпочечниках самцов крыс. Полученные в настоящем исследовании данные впервые демонстрируют новый механизм антиандрогенного действия эндокринного дисраптора ДДТ.</p>

    <p>Dichlorodiphenyltrichloroethane (DDT) is the most widespread systemic pollutant and endocrine disruptor. The effect of prenatal and postnatal exposure to DDT in low doses corresponding to human dietary intake of DDT, considering maximum allowable levels of DDT in food, on the synthesis parameters of male sex hormones in the gonads and adrenal glands of mature male rats was studied. It has been found that after maturation, a reduced level of total testosterone and androstenedione in blood serum is observed in male rats. An investigation into the mechanisms of decreased synthesis of sex hormones showed that rats exposed to low doses of DDT in ontogeny show higher levels of progesterone and reduced levels of 17-oxyprogesterone, a direct precursor of androgen synthesis. Thus, exposure of the developing organism to low doses of DDT did not affect progesterone synthesis, but decreased its hydroxylation, which resulted in progesterone accumulation in the systemic bloodstream and decreased production of male sex hormones in both testes and adrenal glands of male rats. The data obtained in the present study demonstrate for the first time a new mechanism of anti-androgenic action of the endocrine disruptor DDT.</p>
