A prospective single-center cohort comparative study was conducted. The main group included patients with hypoplastic (&lt; 7 mm according to ultrasound data on preovulatory days) endometrium (n = 52), the comparison group consisted of women with normal endometrial thickness (n = 62) (women of both groups with reproductive dysfunctions of unclear cause), the control group included 16 healthy fertile women. An aspiration biopsy of the endometrium was performed on day 6–8 after ovulation with simultaneous collection of peripheral blood sample to measure level of estradiol (P). Endometrial biopsies were examined with histological and immunohistochemical (expression of ER, PR) methods.</p></sec><sec><title>Results</title><p>Results. All women had an ovulatory cycle, serum progesterone level ≥ 16.1 nmol/L (6–8 days after ovulation) and normoestrogenemia. E2/P was similar in all cohorts (p &gt; 0.05). Indicators of endometrial expression of ER, PR, similar to healthy women (n = 16), were found in 21 % (n = 11 out of 52) and 32 % (n = 20 out of 62) in women from main and comparison groups, respectively. The remaining 79 % (n = 41 out of 52) of women with "thin" endometrium (main group) and 68 % (n = 42 out of 62) of patients with normal endometrial thickness (comparison group) had ER and PR expression indices in the endometrial glands and stroma with significant differences (p &lt; 0.05) in all parameters (excepting PR in the endometrial stroma) from those of healthy women (control group), but without relevant differences between these cohorts (p &gt; 0.05) regardless of endometrial thickness.</p></sec><sec><title>Conclusion</title><p>Conclusion. In women with a history of reproductive disorders, parameters of ER and PR expression similar to those in women without reproductive problems, were noted with a "thin" (&lt; 7 mm) endometrium by 50 % less often than those with normal thickness of the uterine mucosa. At the same time, the "thin" endometrium is not an absolute predictor of disorders of the hormone-receptor characteristics of the endometrium: in every fifth case, magnitude of endometrial expression ER, PR similar to healthy women were determined.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: оценить экспрессию рецепторов эстрогенов (ER) и прогестерона (PR) в эндометрии в период «окна имплантации» у женщин с репродуктивными дисфункциями в анамнезе при различной толщине эндометрия.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено проспективное одноцентровое когортное сравнительное исследование. В основную группу вошли 52 пациентки с гипопластическим (&lt; 7 мм по данным ультразвукового исследования в преовуляторные дни) эндометрием, в группу сравнения – 62 женщины с нормальной толщиной эндометрия; женщины обеих групп имели репродуктивные дисфункции неясного генеза. Контрольную группу составили 16 здоровых фертильных женщин. Проводили аспирационную биопсию эндометрия на 6–8-й день после овуляции с одномоментным получением образца периферической крови для определения уровней эстрадиола (E2) и прогестерона (P). Эндометриальные биоптаты исследовали гистологическим и иммунногистохимическим (экспрессия ER и PR) методами.</p></sec><sec><title>Результаты</title><p>Результаты. Все женщины имели овуляторный цикл, уровень прогестерона в сыворотке крови ≥ 16,1 нмоль/л (6–8-й день после овуляции) и нормоэстрогенемию. Отношение Е2/Р было сходным во всех когортах (p &gt; 0,05). Показатели эндометриальной экспрессии ER и PR, сходные со здоровыми женщинами, выявлены у 21 % (у 11 из 52) и 32 % (у 20 из 62) женщин основной группы и группы сравнения соответственно. У остальных 79 % (у 41 из 52) женщин с «тонким» эндометрием (основная группа) и 68 % (у 42 из 62) пациенток с нормальной толщиной эндометрия (группа сравнения) показатели экспрессии ER и PR в железах и строме эндометрия были с достоверными различиями (p &lt; 0,05) по всем значениям (кроме PR в строме эндометрия) от показателей здоровых женщин (контрольная группа), но без соответствующих различий между данными когортами (p &gt; 0,05) независимо от толщины эндометрия.</p></sec><sec><title>Заключение</title><p>Заключение. У женщин с репродуктивными нарушениями в анамнезе показатели эндометриальной экспрессии ER и PR, сходные с таковыми у женщин без репродуктивных проблем, отмечены при «тонком» (&lt; 7 мм) эндометрии на 50 % реже, чем при нормальной толщине слизистой оболочки матки. В то же время «тонкий» эндометрий не является абсолютным предиктором нарушений гормонально-рецепторных характеристик эндометрия: в каждом пятом случае определены сходные со здоровыми женщинами значения эндометриальной экспрессии ER и PR.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рецептивность эндометрия</kwd><kwd>рецепторность эндометрия</kwd><kwd>прогестерон</kwd><kwd>рецепторы эстрогенов</kwd><kwd>рецепторы прогестерона</kwd><kwd>гипопластический эндометрий</kwd><kwd>бесплодие</kwd><kwd>невынашивание беременности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endometrial receptivity</kwd><kwd>endometrial receptors</kwd><kwd>progesterone</kwd><kwd>estrogen receptors</kwd><kwd>progesterone receptors</kwd><kwd>hypoplastic endometrium</kwd><kwd>infertility</kwd><kwd>miscarriage</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">Клинические рекомендации.
