Факторы эффективности использования доноров
 для получения ооцитов у крупного рогатого скота

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.
