This case-control analysis comprised 118 patients who responded normally to ovarian stimulation with a GnRH antagonist protocol at Hue Center for Reproductive Endocrinology and Infertility, Vietnam, between January 2018 and October 2019. Recruitment was achieved through case-control matching: a case (with Dual trigger – group A) was paired with control (with hCG trigger – group B) in a 1:1 ratio. The primary markers of success were the retrieval of oocytes and embryological data, the pregnancy rate, and the incidence of ovarian hyperstimulation syndrome (OHSS).</p></sec><sec><title>Results</title><p>Results. 59 patients in group A and 59 women in group B were recruited. Two groups had comparable patient characteristics and ovarian reserve. The initial dose, total dose, duration of gonadotropin administration, and peak of estradiol level were not statistically different across groups. The number of recovered oocytes (10.3 ± 4.2 vs. 10.0 ± 3.3; p = 0.663), mature oocytes (8.6 ± 3.7 vs.</p></sec><sec><title>8</title><p>8.1 ± 2.8; p = 0.346), and high-quality embryos (56.2 ± 28.9 vs. 59.8 ± 35.9; p = 0.555) was equivalent. Fertilization, clinical pregnancy, and live birth rates were comparable between the dual trigger and hCG groups. In neither group were any occurrences of OHSS seen.</p></sec><sec><title>Conclusion</title><p>Conclusion. Dual trigger may substitute hCG for final oocyte maturation and fresh embryo transfer in patients with normal responses to GnRH antagonist protocol-induced ovarian stimulation without compromising IVF outcomes.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель: оценить влияние двойного триггера овуляции агониста гонадотропин-рилизинг-гормона (ГнРГ) и низких доз хорионического гонадотропина человека (ХГЧ) на исходы экстракорпорального оплодотворения (ЭКО) у женщин с нормальным овариальным ответом.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование «случай–контроль» были включены 118 пациенток с нормальным ответом на стимуляцию яичников с применением протокола с антагонистом ГнРГ. Исследование проводилось в Центре репродуктивной эндокринологии и бесплодия Хюэ (Вьетнам) в период с января 2018 г. по октябрь 2019 г. Набор пациенток проводился путем сопоставления «случай–контроль»: случай (применение двойного триггера – группа А) сопоставлялся с контролем (применение триггера ХГЧ – группа Б) в соотношении 1:1. Основными маркерами успеха были: получение ооцитов и эмбриологические характеристики, частота наступления беременности и частота синдрома гиперстимуляции яичников (СГЯ).</p></sec><sec><title>Результаты</title><p>Результаты. В исследование были включены 59 пациенток из группы А и 59 женщин из группы Б с сопоставимыми характеристиками и овариальным резервом. Между группами не отмечено статистических отличий в начальной дозе, общей дозе, продолжительности введения гонадотропина и пиковом уровне эстрадиола. Количество сформированных ооцитов (10,3 ± 4,2 против 10,0 ± 3,3; p = 0,663), зрелых ооцитов (8,6 ± 3,7 против 8,1 ± 2,8; p = 0,346) и эмбрионов высшего качества (56,2 ± 28,9 против 59,8 ± 35,9; p = 0,555) были сходными в обеих группах. Также между группами были сопоставимы показатели фертилизации, наступления клинической беременности и частоты живорождения, случаи СГЯ в обеих группах не наблюдались.</p></sec><sec><title>Заключение</title><p>Заключение. Двойной триггер овуляции может заменить ХГЧ для окончательного созревания ооцитов при переносе свежих эмбрионов у пациенток с нормальным ответом на стимуляцию яичников в протоколе с применением антагонистов ГнРГ, без влияния на исход ЭКО.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>двойной триггер</kwd><kwd>агонист гонадотропин-рилизинг-гормона</kwd><kwd>ГнРГ</kwd><kwd>антагонист ГнРГ</kwd><kwd>нормальный респондер</kwd><kwd>синдром гиперстимуляции яичников</kwd><kwd>СГЯ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dual trigger</kwd><kwd>gonadotrophin-releasing hormone (GnRH) agonist</kwd><kwd>GnRH antagonist</kwd><kwd>normal responder</kwd><kwd>ovarian hyperstimulation syndrome</kwd><kwd>OHSS</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">Haas J., Zilberberg E., Kedem A. et al.
