However, the underlying pathogenic mechanisms and associated outcomes have not been thoroughly investigated.</p> <p><bold>Aim:</bold> To develop an optimal Oryctolagus cuniculus model for fetal growth restriction and to establish a methodology for its application.</p> <p><bold>Methods:</bold> The early fetal growth restriction was modeled by the uterine artery ligation prior to the onset of O. cuniculus pregnancy. The model of late fetal growth restriction was induced by the artery ligation on the 25th day of gestation. The fetoplacental unit was obtained on the 30th day of gestation through a cesarean section of O. cuniculus.</p> <p><bold>Results:</bold> In the group of late fetal growth restriction, there was a significant decrease in fetal and placental weights compared to the control group (p &lt;0.05). However, no significant differences in these parameters were observed between the model of early fetal growth restriction and control animals (p &gt;0.05).</p> <p><bold>Conclusion:</bold> This study has demonstrated two different models of fetal growth restriction. The findings of this study suggest that the approach of late fetal growth restriction, which involves the uterine artery ligation on the 25th day of gestation, is a more viable and promising option for further exploration and implementation into the scope of experimental obstetrics.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> По данным Всемирной организации здравоохранения, задержка роста плода встречается примерно в 10% беременностей. Однако механизмы, лежащие в основе его патогенеза и связи с последующими исходами, изучены недостаточно.</p> <p><bold>Цель</bold> — создание оптимальной модели задержки роста плода у Oryctolagus cuniculus и отработка методики ее проведения.</p> <p><bold>Материалы и методы.</bold> Моделирование «ранней» задержки развития плода осуществляли путем наложения лигатур на маточные сосуды до момента наступления беременности O. cuniculus. Модель «поздней» задержки развития плода реализовывали с помощью наложения лигатур на 25-й день беременности животных. Плодово-плацентарный комплекс получали на 30-й день гестации посредством кесарева сечения O. cuniculus.</p> <p><bold>Результаты. </bold>В группе «поздней» задержки развития плода вес плода и плаценты значимо снизились в сравнении с контролем (p &lt;0,05), значимые различия этих параметров в модели «ранней» задержки развития плода не были найдены (p &gt;0,05).</p> <p><bold>Заключение.</bold> Нами продемонстрированы две разные модели задержки развития плода. Согласно полученным нами результатам, методика «поздней» задержки развития плода (наложение лигатур на маточные сосуды на 25-й день беременности) является более приоритетной и адекватной, а также перспективной для дальнейшей отработки и применения в экспериментальном акушерстве.</p></trans-abstract><kwd-group xml:lang="en"><kwd>fetal growth restriction</kwd><kwd>biological models</kwd><kwd>placental insufficiency</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>задержка развития плода</kwd><kwd>биологические модели</kwd><kwd>плацентарная недостаточность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Swanson AM, David AL.
