Экспериментальной  группе  Ф-100  вводили  эстрогеновый  препарат  фулвестрант  0.4 мл  в  виде  0.0005% масляного  раствора в  дозе  100 мкг/кг,  контрольной группе вводили  стерильное  касторовое  масло в  дозе 0.8 мкг/кг. Измерение массы тела аногенитального расстояния (далее АГР), индекса АГР было выполнено на  половозрелом  потомстве  лабораторных  мышей  мужского  и  женского  пола.  Полученные  данные  подвергались статистической обработке.</p></sec><sec><title>Результаты</title><p>Результаты.Воздействие препарата синестрола в дозе 50 мкг/кг на потомство мужского пола приводило к укорочению АГР в сравнении с контрольной группой. Препарат фулвестрант в дозе 100 мкг/кг блокирует эстрогеновые рецепторы, в результате работают только андрогеновые, приводящие к усилению маскулинизирующего эффекта, при таком эффекте у потомства мужского пола наблюдалось незначительное увеличение АГР по сравнению с группой контроля.  Величина АГР у самок в группе С-50 уменьшалась по  сравнению  с  группой  контроля,  этот  показатель  можно  считать  феминизирующим  отсроченным  эффектом. Экспериментальная группасамок потомства Ф-100 существенных статистически значимых изменений не показала.</p></sec><sec><title>Заключение</title><p>Заключение.Изучение дозозависимых эффектов пренатального введения эстрогенов продемонстрировало как стимулирующее, так и ингибирующее воздействие гормонов на величину АГР. Исследование  зависимости  АГР  от  пренатального  эффекта  эстрогенов  позволяет  спрогнозировать  патологические изменения репродуктивной системы потомства.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aimof this research was to study an anogenital distance of the offspring of laboratory mice after prenatal exposure to estrogens.</p><sec><title>Material  and  methods</title><p>Material  and  methods. The  study  included  sexually  mature  laboratory  mice  and  their  mothers  that were injected with various single doses of estrogen preparations intramuscularly at the E 11.5 gestation stage. The mice of the experimental group C-50 were injected with 2% oil solution of synestrol, dosage 50 μg/kg, the mice of the control group were injected with olive oil, dosage 0.2 μg/kg. The mice of the experimental group F-100 were injected with 0.4 ml of 0.0005% fulvestrant oil solution, dosage 100  μg/kg, the mice of the control group were injected with sterile castor oil, dosage 0.8 μg/kg. The body weight, the anogenital distance (AGD), the AGD index were measured in sexually mature offspring of laboratory mice, male and female. The data obtained were statistically processed.</p></sec><sec><title>Results</title><p>Results.The  exposure  of  male  offspring  to  synestrol,  dosage  50  μg/kg,  caused  an AGD reduction  compared with the mice in the control group. Fulvestrant, dosage 100  μg/kg, blocked estrogen receptors; as a result, only androgen receptors worked, the fact leading to an increased masculinizing effect; with this effect a slight increase in AGD was observed in male offspring compared to the mice of the control group. The AGD parameters in female mice of the experimental group C-50 decreased compared with the mice of the control group; this parameter can be considered as a feminizing delayed effect. The female mice of the experimental group F-100 showed no statistically significant changes.</p></sec><sec><title>Conclusion</title><p>Conclusion.The study of dose-dependent effects of prenatal estrogen administration demonstrated both stimulating and inhibitory effects of hormones on the AGD parameters. The study of AGD dependence onthe prenatal effect of estrogens allows early identification of pathological changes in the reproductive system of the offspring.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аногенитальное расстояние</kwd><kwd>масса тела</kwd><kwd>потомство</kwd><kwd>лабораторные мыши</kwd><kwd>эстрогены</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anogenital distance</kwd><kwd>body weight</kwd><kwd>offspring</kwd><kwd>laboratory mice</kwd><kwd>estrogens</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">Гуськова Т.А.
