Исследование было рандомизированным, выделены три группы. Первая группа – контрольная, контролем служили четыре собаки. Во второй группе была проведена гемитиреоидэктомия, третьей группе – субтотальная тиреоидэктомия. Операции проводились под общим обезболиванием. Объектом исследования служили семенники, щитовидная железа и кровь. В послеоперационном периоде был проведен биохимический и гистологический анализы удаляемой ткани щитовидной железы и семенников обследуемых собак. Определение гормонов в крови до и после операции проводилось с помощью хемилюминесцентного анализатора Roche Codas E601 (Швейцария).Результаты: в ходе проведенного исследования в послеоперационном периоде у экспериментальных собак в сыворотке крови на 5–8-е сутки имело место уменьшение тестостерона на 15%, а на 20-е – с 15 до 30,1%; у собак после субтотальной тиреоидэктомии этот показатель на 20-е сутки составил 41,1% (р &lt; 0,005). Изменение ФСГ и пролактина в крови было различно во всех группах. Показатель ФСГ на 5–8-е сутки имел достоверное повышение, а на 20-е – снижение, а показатель пролактина наоборот: уменьшение на 5–8 сутки и повышение на 20-е сутки. Гормональная активность щитовидной железы была снижена, особенно после субтотальной тиреоидэктомии. Морфологические исследования показали заметное снижение активности сперматогенного слоя и интерстициальный отек семенников на 5–8-е сутки в обеих группах. На 30-е сутки в обеих группах после операции отмечается заметное снижение как сперматогенного слоя, так и интерстициальных клеток семенников.Заключение: результаты экспериментальных исследований показали, что в результате гемитиреоидэктомии и субтотальной тиреоидэктомии отмечаются заметное изменение регуляции сперматогенеза и структурно-функциональные изменения семенников экспериментальных животных, особенно в йододефицитом регионе.</p></abstract><trans-abstract xml:lang="en"><p>Materials and Methods: experimental studies were performed on 20 mongrel male dogs. The study was randomized, 3 groups were identified. The first group was a control group, 4 dogs served as controls. Hemithyroidectomy was performed in the second group, subtotal thyroidectomy was performed in the third group. The operations were performed under general anesthesia. The testes, thyroid gland and blood were the objects of the study. In the postoperative period, biochemical and histological analyses of the removed thyroid gland tissue and testicles of the examined dogs were performed. The determination of hormones in the blood before and after surgery was carried out using a chemiluminescent analyzer Roche Codas E601 (Switzerland).Results: in the course of the study, in the postoperative period, experimental dogs had a decrease in testosterone in serum by 15% on day 5-8, and from 15% to 30.1% on day 20; in dogs after subtotal thyroidectomy, this indicator was 41.1% on day 20 (p &lt; 0.005). Changes in FSH and prolactin in the blood were different in all groups. The FSH index had a significant increase on day 5-8, and a decrease on day 20, and the prolactin index on the contrary: a decrease on day 5-8 and an increase on day 20. The hormonal activity of the thyroid gland was reduced, especially after subtotal thyroidectomy. Morphological studies have shown a marked decrease in the activity of the spermatogenic layer and interstitial edema of the testes on 5-8 days in both groups. On the 30th day, in both groups after surgery, there was a noticeable decrease in both the spermatogenic layer and the interstitial cells of the testes.Conclusion: the results of experimental studies have shown that as a result of hemithyroidectomy and subtotal thyroidectomy, there is a noticeable change in the regulation of spermatogenesis and structural and functional changes in the testes of experimental animals, especially in the iodine-deficient region.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>послеоперационный гипотиреоз</kwd><kwd>сперматогенез</kwd><kwd>семенники</kwd><kwd>гормоны</kwd><kwd>гемитиреоидэктомия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>postoperative hypothyroidism</kwd><kwd>spermatogenesis</kwd><kwd>semens</kwd><kwd>hormones</kwd><kwd>hemitireoidectomy</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">Каркищенко В.Н, Семенов Х.Х., Каркишенко Н.Н.
