Скрытый (прелатентный) дефицит железа на прегравидарном этапе ведет к осложнениям как со стороны матери, так и плода, приводит к снижению частоты живорождений в протоколах вспомогательных репродуктивных технологий (ВРТ). Цель. Определить качество и количество ооцитов в программах ВРТ у пациенток с прелатентным дефицитом железа, оценить исходы стимуляции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведен анализ 808 историй протоколов ВРТ. У 10,6% пациенток выявлен прелатентный дефицит железа (уровень ферритина ниже 30-50 мкг/л). Проведена оценка возраста, веса, длительности бесплодия и его причин, изучены показатели общего анализа крови, уровень ферритина, другие маркеры анемии в основной группе - группа 1 (n = 86) и в группе сравнения - группа 2 (n = 29). Изучен уровень гормонов, оценено количество и качество ооцитов, число эмбрионов и исходы протоколов ВРТ.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено влияние уровня ферритина на исходы в программах ВРТ. Прелатентный дефицит железа умеренно связан с частотой наступления беременности (R = 0,214). На частоту наступления беременности также влияет уровень АМГ (R = -0,351). Между группами исходно выявлена значимая разница в уровне ферритина (р = 0,00) и числе антральных фолликулов (р = 0,00). У 84,9% в 1-й группе получены зрелые ооциты, во 2-й группе - у 94,0%. Число зрелых ооцитов в 1-й группе составило 5,8 ± 4,41 и во 2-й группе - 11,42 ± 4,67 (р = 0,00). У пациенток с прелатентным дефицитом железа получено 2,19 ± 1,73 эмбриона и у пациенток без дефицита ферритина - 3,2 ± 1,44 эмбриона. Проведенный анализ показал влияние уровня ферритина, соответствующего прелатентному дефициту железа, на качество ооцитов в протоколах ВРТ.</p></sec><sec><title>Выводы</title><p>Выводы. Своевременная коррекция прелатентного дефицита железа будет способствовать увеличению числа зрелых ооцитов, повышению количества эмбрионов, а также профилактике осложнений беременности. При подготовке к ВРТ необходимо определять вместе с яичниковым резервом и уровень ферритина.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Hidden iron deficiency at the pregravidary stage leads to complications from both the mother and foetus, to decrease in the frequency of live birth in the protocols of assisted reproductive technologies (ART).</p></sec><sec><title>Aim</title><p>Aim. Is to determine the quality and number of oocytes in ART programs in patients with hidden iron deficiency and estimate the pregnancy outcomes.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We analyzed 808 of protocols in ART. There were 10.6% patients with hidden iron deficiency with ferritin levels below 30-50 pg/l. The age, weight, duration of infertility and its causes were assessed in the 1st (n = 86) and 2nd (n = 29) groups. The blood count, ferritin levels and other markers of anemia were studied. Hormone levels, the number and quality of oocytes, and the number of embryos and the outcomes of ART protocols have been assessed.</p></sec><sec><title>Results</title><p>Results. The impact of ferritin levels in ART programs has been revealed. Hidden iron deficiency is moderately associated with the frequency of pregnancy (R = 0,214). The rate of pregnancy is also affected by anti-müllerian hormone (R = -0,351). Mature oocytes are obtained in 84.9% of women in the 1st group and 94% - in the 2nd group. Patients with hidden iron deficiency received 2.19 ± 1.73 embryos and without ferritin deficiency - 3.2 ± 1.44 embryos. The analysis demonstrated the effect of ferritin levels on the quality of oocytes in the ART protocols. In addition to ferritin levels, an important factor are the levels of AMH and number of antrum-containing follicles, which affect the number of mature oocytes.</p></sec><sec><title>Conclusion</title><p>Conclusion. Timely correction of hidden iron deficiency will help to increase the number of mature oocytes, to increase the quality and quantity of embryos as well as to prevent pregnancy complications. In preparation for ART, together with assessment of ovary reserve, it is necessary to determine the level of ferritin.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>прелатентный дефицит железа</kwd><kwd>качество ооцитов</kwd><kwd>антимюллеровый гормон</kwd><kwd>ферритин</kwd><kwd>железодефицитная анемия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hidden iron deficiency</kwd><kwd>quality of oocytes</kwd><kwd>anti-müllerian hormone</kwd><kwd>assisted reproductive technology</kwd><kwd>ferritin</kwd><kwd>iron deficiency anemia</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">Kassebaum NJ, Bertozzi-Villa A, Coggeshall MS, Shackelford KA, Steiner C, Heuton KR et al.
