Normal ovarian reserve (OR) determining the ovarian response to follicle development containing fully-featured oocytes is an important factor in pregnancy, including assisted reproductive technology (ART) programs. The causes of premature OR decrease are multifactorial. The study of gene polymorphism as a cause of the premature OR decrease deserves attention.</p></sec><sec><title>Aim</title><p>Aim: to determine genetic predisposition to premature OR decrease and create a prognostic model based on study results.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. A retrospective comparative cohort study was conducted. A total of 200 reproductively active patients with infertility underwent ART were examined. The patients were divided into 2 groups: Group 1 included 100 patients with a premature OR decrease; Group 2 consisted of 100 patients with a normal OR. All patients underwent molecular genetic study. Genetic polymorphisms of the genes ESR1, ESR2, FSHR, CYP19A were studied.</p></sec><sec><title>Results</title><p>Results. The final clinical phenotype is shaped by multiple factors – genetic and environmental. Several genetic variants contribute to the formation of premature decrease in ovarian reserve. Gene combination of CYP19A1 and FSHR displayed the greatest synergistic effect, potentiating each other and predisposing to a poor ovarian response as part of stimulated superovulation.</p></sec><sec><title>Conclusion</title><p>Conclusion. Identifying genetic markers is a promising method for individual OR evaluation, including its premature decline. Multilocus analysis and a prognostic model based on combining several polymorphic gene variants will allow to assess risks of premature OR decrease and individualize ART programs.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. Важным фактором наступления беременности, в том числе и в программах вспомогательных репродуктивных технологий (ВРТ), является нормальный овариальный резерв (ОР), который определяет ответ яичников к развитию фолликула с полноценной яйцеклеткой. Причины преждевременного снижения ОР многофакторны. Заслуживает внимания исследование полиморфизма генов как причины преждевременного снижения ОР.</p></sec><sec><title>Цель</title><p>Цель: определение генетической предрасположенности к преждевременному снижению ОР и создание на основании полученных результатов прогностической модели.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено ретроспективное когортное сравнительное исследование. Обследовано 200 пациенток с бесплодием, которые реализовывали репродуктивную функцию с помощью ВРТ. Пациентки были разделены на 2 группы: в группу 1 вошли 100 пациенток с преждевременным снижением ОР, группу 2 составили 100 пациенток с нормальным ОР. Всем пациенткам проведено молекулярно-генетическое исследование. Исследованы генетические полиморфизмы следующих генов: ESR1, ESR2, FSHR, CYP19A.</p></sec><sec><title>Результаты</title><p>Результаты. Итоговый клинический фенотип формируется за счет множества факторов – генетических и средовых. Вклад в формирование преждевременного снижения ОР вносят несколько генетических вариантов. Наибольшим синергичным эффектом обладает комбинация генов CYP19A1 и FSHR, которые потенцируют друг друга и предрасполагают к бедному ответу яичников в рамках стимуляции суперовуляции.</p></sec><sec><title>Заключение</title><p>Заключение. Перспективным методом индивидуальной оценки ОР, в том числе и преждевременного его снижения, является определение генетических маркеров. Мультилокусный анализ и прогностическая модель на основании сочетания нескольких вариантов полиморфных генов позволят оценить риски преждевременного снижения ОР и индивидуализировать программу ВРТ.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бедный овариальный ответ</kwd><kwd>овариальный резерв</kwd><kwd>ОР</kwd><kwd>бесплодие</kwd><kwd>гены ESR1 и FSHR</kwd><kwd>вспомогательные репродуктивные технологии</kwd><kwd>ВРТ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>poor ovarian response</kwd><kwd>ovarian reserve</kwd><kwd>OR</kwd><kwd>infertility</kwd><kwd>ESR1 and FSHR genes</kwd><kwd>assisted reproductive technologies</kwd><kwd>AR</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">Радзинский В.Е.
