Обзор посвящен анализу факторов, оказывающих влияние на эффективность использования доноров для получения ооцитов посредством аспирации фолликулов яичников под ультразвуковым контролем (OPU) у крупного рогатого скота. Во введении подчёркивается постепенная замена производства эмбрионов in vivo продукцией эмбрионов, полученных in vitro
 из ооцитов, извлеченных посредством OPU. Это делает важным решение задачи повышения количества и качества ооцитов, получаемых от самок-доноров. Материалом для исследований служили научно информационные источники, представленные в российских и международных базах (E-Library, Wiley, Elsevier, ResearchGate, PubMed), статистические и аналитические данные комитета по сбору данных Международного общества эмбриональных технологий (IETS) (https://www.iets.org/ Committees/Data-Retrieval-Committee). Для написания обзора был отобран 151 первоисточник. Проведен краткий анализ современного состояния исследований особенностей полового цикла самок крупного рогатого скота. Описаны методы, которые помогают улучшить результаты OPU у коров. Среди них: подбор оптимальных технических параметров процедуры, проведение OPU на определенной стадии развития фолликулов, стимуляция роста и созревания фолликулов с помощью гонадотропинов, а также использование биомаркеров для отбора лучших коров-доноров. Показан вклад собственных исследований авторов в решение вышеназванной научной проблемы.

This review analyzes the factors influencing the effectiveness of using donors for oocyte retrieval via ultrasound-guided ovarian follicle aspiration — Ovum Pick-Up (OPU), in cattle. The introduction highlights the gradual shift from in vivo embryo production to the production of embryos obtained in vitro from oocytes retrieved via OPU. This makes it crucial to address the challenge of increasing the quantity and quality of oocytes obtained from female donors. The research material consisted of scientific and informational sources available in Russian and international databases (E-Library, Wiley, Elsevier, ResearchGate, PubMed), as well as statistical and analytical data from the Data Collection Committee of the International Embryo Technology Society (IETS) (https://www.iets.org/Committees/Data-Retrieval-Committee). A total of 151 primary sources were selected for this review. A brief analysis of the current state of research on the characteristics of the estrous cycle in female cattle was conducted. Methods that help improve OPU outcomes in cows are described. These include: selecting optimal technical parameters for the procedure, performing OPU at a specific stage of follicular development, stimulating follicular growth and maturation using gonadotropins, and using biomarkers to select the best donor cows. The authors’ own research contributions to addressing the scientific problem are highlighted.
