Достаточно часто пациенты с бесплодием нуждаются в помощи вспомогательных репродуктивных технологий для решения своей проблемы. Две трети неудач в циклах ВРТ связаны с недостаточностью восприимчивости эндометрия.</p></sec><sec><title>Цель</title><p>Цель. Оценить эффективность применения эстрадиола валерата (Прогинова®) у женщин с тонким эндометрием в циклах ВРТ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены пациентки с тонким эндометрием ≤ 7,0 мм по данным ультразвукового исследования (УЗИ) органов малого таза на 10–14-й день менструального цикла (пик содержания в крови лютеинизирующего гормона (ЛГ) или в день назначения прогестерона в цикле заместительной гормональной терапии). Пациентки с тонким эндометрием (n = 74) были разделены на две группы: 1-я группа (n = 43) – пациентки с хроническим эндометритом, установленным по данным гистологического исследования и иммуногистохимии (ИГХ); 2-я группа (n = 31) – пациентки с тонким эндометрием без хронического эндометрита. Все пациентки получали препарат эстрадиола валерата по одной из схем: 4 мг эстрадиола валерата в естественном цикле с момента достижения доминантным фолликулом диаметра 13 мм или 4 мг эстрадиола валерата с 3-го дня менструального цикла.</p></sec><sec><title>Результаты</title><p>Результаты. Назначение эстрадиола валерата статистически значимо увеличивало толщину эндометрия у женщин с тонким эндометрием (p &lt; 0,05). Прирост толщины эндометрия у пациенток 1-й группы в среднем составлял 1,9279 мм, у пациенток 2-й группы – 2,09 мм. Средняя толщина эндометрия до лечения эстрадиолом валерата составляла 6,315 (4,7; 7,0) мм, после лечения – 8,311 (5,6; 11,0). Беременность в цикле ЭКО или ПЭ наступила у 44 пациенток с тонким эндометрием (62,5%) после лечения эстрадиолом валерата.</p></sec><sec><title>Выводы</title><p>Выводы. Применение эстрадиола валерата в циклах ЭКО и ПЭ увеличивает толщину эндометрия и повышает частоту наступления беременности и живорождения у пациенток с тонким эндометрием.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Patients with infertility often require the help of assisted reproductive technologies to solve their problem. Two thirds of failures in ART cycles are associated with insufficient endometrial receptivity.</p></sec><sec><title>Aim</title><p>Aim. To evaluate the effectiveness of using estradiol valerate 2 mg (Progynova®) in women with thin endometrium in ART cycles.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included patients with a thin endometrium ≤ 7.0 mm according to the ultrasound examination (US) of the pelvic organs on the 10–14th day of the menstrual cycle (peak of luteinizing hormone (LH) in the blood or on the day of progesterone administration in the hormone replacement therapy cycle). Patients with a thin endometrium (n = 74) were divided into two groups: the first group (n = 43) – patients with chronic endometritis established by histological examination and immunohistochemistry (IHC); group 2 (n=31) – patients with a thin endometrium without chronic endometritis. All patients received estradiol valerate according to one of the following regimens: 4 mg estradiol valerate in a natural cycle from the moment the dominant follicle reached a diameter of 13 mm or 4 mg estradiol valerate from day 3 of the menstrual cycle.</p></sec><sec><title>Results</title><p>Results. Administration of estradiol valerate statistically significantly increased the endometrial thickness in women with thin endometrium (p &lt; 0.05). The increase in endometrial thickness in patients of group 1 averaged 1.9279 mm, in patients of group 2 – 2.09 mm. The average endometrial thickness before treatment with estradiol valerate was 6.315 (4.7; 7.0) mm, after treatment – 8.311 (5.6; 11.0). 70 of 74 (94.6%) patients had an endometrial thickness of &gt; 7 mm. Pregnancy in an IVF or PE cycle occurred in 44 patients with thin endometrium (62.5%) after treatment with estradiol valerate.</p></sec><sec><title>Conclusions</title><p>Conclusions. The use of estradiol valerate in IVF and ET cycles increases the thickness of the endometrium and increases the frequency of pregnancy and live birth in patients with a thin endometrium.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тонкий эндометрий</kwd><kwd>хронический эндометрит</kwd><kwd>эстрадиола валерат</kwd><kwd>ЭКО</kwd><kwd>ооциты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thin endometrium</kwd><kwd>chronic endometritis</kwd><kwd>estradiol valerate</kwd><kwd>IVF</kwd><kwd>oocytes</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">Sehring J, Beltsos A, Jeelani R.
