In addition to an increase in the frequency of chromosomal abnormalities, an important pathogenetic mechanism of age-associated decline in oocyte quality is mitochondrial dysfunction due to the progressive depletion of endogenous coenzyme Q10 (CoQ10), a key cofactor of oxidative phosphorylation and a major intracellular antioxidant.</p> <p><bold>Objective: </bold>Systematic analysis of the biological mechanisms of CoQ10 action and assessment of the clinical effectiveness of its use in ART programs in women with ROR based on current data.</p> <p><bold>Results: </bold>An age-related decrease in CoQ10 synthesis (due to impaired Pdss2 and Coq6 gene expression) reproduces the pathological patterns of oocyte mitochondrial dysfunction: a decrease in ATP production and an increase in the frequency of spindle abnormalities. The largest meta-analysis (Lin et al., 2024; 6 RCTs; n=1529) showed that the preliminary use of CoQ10 was associated with a statistically significant increase in the clinical pregnancy rate (OR=1.84, 95% CI 1.33–2.53), the number of oocytes obtained and quality embryos, a decrease in the dose of gonadotropins and the rate of cycle discontinuation. According to network meta-analyses, among other adjuvants, CoQ10 demonstrates the greatest efficacy in relation to the frequency of live birth compared with DHEA, growth hormone and testosterone. The available evidence base is characterized by significant limitations: small samples, predominance of surrogate markers over live birth as the primary endpoint, and heterogeneity of administration regimens.</p> <p><bold>Conclusion: </bold>CoQ10 has a clear pathogenetic rationale for adjuvant use in ART programs in women with ROR and a favorable safety profile. However, current international clinical guidelines (ESHRE, ASRM) do not include CoQ10 in the list of recommended interventions due to insufficient evidence. Its use is individual and requires informing the patient about the current status of the drug.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность: </bold>Устойчивая тенденция к откладыванию деторождения определяет рост доли пациенток со сниженным овариальным резервом (СОР) в программах вспомогательных репродуктивных технологий (ВРТ). Помимо увеличения частоты хромосомных аномалий важным патогенетическим механизмом возраст-ассоциированного снижения качества ооцитов является митохондриальная дисфункция, обусловленная прогрессирующим истощением эндогенного коэнзима Q10 (КоQ10) – ключевого кофактора окислительного фосфорилирования и основного внутриклеточного антиоксиданта.</p> <p><bold>Цель работы: </bold>провести систематический анализ биологических механизмов действия КоQ10 и оценить клиническую эффективность его применения в программах ВРТ у женщин с СОР на основе актуальных данных.</p> <p><bold>Результаты: </bold>Возрастное снижение синтеза КоQ10 (вследствие нарушения экспрессии генов Pdss2 и Coq6) воспроизводит патологические паттерны митохондриальной дисфункции ооцитов: снижение продукции АТФ и увеличение частоты аномалий веретена деления. Крупнейший мета-анализ (Lin и соавт., 2024; 6 РКИ; n=1529) показал, что предварительное применение КоQ10 ассоциировано со статистически значимым увеличением частоты клинической беременности (OШ=1,84, 95% ДИ: 1,33–2,53), числа полученных ооцитов и качественных эмбрионов, снижением дозы гонадотропинов и частоты отмены цикла. По данным сетевых мета-анализов, среди других адъювантов КоQ10 демонстрирует наибольшую эффективность в отношении частоты живорождения по сравнению с ДГЭА, гормоном роста и тестостероном. Имеющаяся доказательная база характеризуется существенными ограничениями: небольшими выборками, преобладанием суррогатных маркеров над живорождением в качестве первичной конечной точки и гетерогенностью режимов введения.</p> <p><bold>Заключение: </bold>КоQ10 обладает четким патогенетическим обоснованием применения в качестве адъюванта в программах ВРТ у женщин с СОР и благоприятным профилем безопасности. Вместе с тем действующие международные клинические руководства (ESHRE, ASRM) не включают КоQ10 в перечень рекомендованных вмешательств ввиду недостаточного уровня доказательств. Его применение носит индивидуальный характер и требует информирования пациентки о текущем статусе препарата.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coenzyme Q10</kwd><kwd>ubiquinone</kwd><kwd>reduced ovarian reserve</kwd><kwd>assisted reproductive technologies</kwd><kwd>IVF</kwd><kwd>mitochondrial dysfunction</kwd><kwd>oocyte quality</kwd><kwd>reproductive aging</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>коэнзим Q10</kwd><kwd>убихинон</kwd><kwd>сниженный овариальный резерв</kwd><kwd>вспомогательные репродуктивные технологии</kwd><kwd>ЭКО</kwd><kwd>митохондриальная дисфункция</kwd><kwd>качество ооцитов</kwd><kwd>репродуктивное старение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Churilova E.V., Andreev E.M., Chertenkov K.O. et al.
