Диагностика мужского бесплодия основана на анализе эякулята (спермы). К исследуемым параметрам спермы относятся: концентрация и подвижность сперматозоидов, а также их морфология. Модели лабораторных животных позволяют изучать различные биологические процессы, включая воздействие внешних и внутренних факторов на процессы репродукции. Однако до настоящего времени отсутствует простой, безопасный клеточносберегающий способ получения сперматозоидов у животных.</p><sec><title>Цель</title><p>Цель. Разработать методику прижизненного получения сперматозоидов с использованием оптимальных параметров электростимуляции у крыс Wistar для изучения влияния факторов внешней среды на репродуктивную способность животных.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование выполнено на 30 крысах-самцах Wistar массой 280–300 г.</p><p>Для получения сперматозоидов использовали ректальный электростимулятор для получения эякулята у животных. Для анализа и подсчета сперматозоидов использовали камеру Горяева и микроскопы 2 видов: «Микромед P-1 LED», Россия; цифровой микроскоп «Levenhuk D90L LCD», Китай.</p></sec><sec><title>Результаты</title><p>Результаты. Все животные были поделены на 6 групп по пять особей в каждой в зависимости от режима электростимуляции. Все используемые режимы электростимуляции позволяли добиться эрекции во всех группах животных. Однако было установлено, что наиболее безопасным и клеточносберегающим способом получения сперматозоидов является ректальная электростимуляция семенных бугорков крыс при показателях электрического тока 60 Гц и 4 В.</p></sec><sec><title>Вывод</title><p>Вывод.

In more than 30 % of cases, infertility is attributed to male factors. The diagnosis of male infertility is based on semen analysis. The assessed semen parameters include sperm concentration, motility, and morphology. Laboratory animal models enable the study of various biological processes, including the effects of external and internal factors on reproduction processes. However, to date, there is no simple, safe, non-terminal method for sperm collection in animals.</p></sec><sec><title>Aim</title><p>Aim. To develop a non-terminal sperm collection technique using optimal electrical stimulation parameters in Wistar rats to study the influence of environmental factors on the reproductive function.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was performed on 30 male Wistar rats weighing 280–300 g. For sperm collection, a rectal electrical stimulator was used to obtain ejaculate. A hemocytometer and two types of microscopes were used for sperm analysis and counting: a Micromed P-1 LED (Russia) and a Levenhuk D90L LCD digital microscope (China).</p></sec><sec><title>Results</title><p>Results. All animals were divided into 6 groups of five individuals each, according to the electrical stimulation protocol. All stimulation protocols resulted in erection in all groups of animals. However, the safest and most cell-saving method was found to be rectal electrical stimulation of the seminal colliculus of rats at settings of 60 Hz and 4 V.</p></sec><sec><title>Conclusion</title><p>Conclusion. A method for sperm collection in Wistar rats with an optimized electrical stimulation protocol has been developed, enabling the study of various factors affecting male fertility.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>прижизненное получение эякулята</kwd><kwd>ректальный электростимулятор</kwd><kwd>оптимальные параметры электростимуляции животных</kwd><kwd>количество и морфология сперматозоидов</kwd><kwd>факторы внешней среды</kwd><kwd>репродукция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-terminal ejaculate collection</kwd><kwd>rectal electrostimulator</kwd><kwd>optimal electrical stimulation parameters</kwd><kwd>sperm count and morphology</kwd><kwd>environmental factors</kwd><kwd>reproduction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта программы УМНИК (договор № 18682ГУ/2023) и гранта ФГБОУ ВО «Кировский ГМУ» Минздрава России № 7-2026-ГРАНТ</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Babakhanzadeh E, Nazari M, Ghasemifar S, Khodadadian A.
