   <abstract xml:lang="ru">
    <p>Настоящее исследование было посвящено актуальной проблеме в области ветеринарной медицины, а именно, безопасности длительного применения кошкам моногормонального препарата на основе мегестрола ацетата на примере ЛП СексКонтроль (капли).&#13;
Установлено, что в результате применения ЛП СексКонтроль (капли) у кошек, согласно инструкции в дозах 2,5 мг на кошку в неделю в течение 18 месяцев, отмечается устойчивое блокирование репродуктивной функции. После отмены препарата в течение 24 месяцев не зарегистрировано признаков возобновления половой цикличности. Вероятно, что ЛП СексКонтроль вызывает глубокие нарушения в центрах регуляции половой функции кошек (в нейроэндокринной оси гипоталамус-гипофиз-гонады), которые можно трактовать как тяжелую овариальную дисфункцию. Не исключено, что при этом затронуты и другие центры нейроэндокринной регуляции организма, что подтверждается наблюдаемыми у подопытных животных таких явлений, как апатия (снижение двигательной активности, отказ от игр, отказ от взаимодействия с другими кошками), затяжная линька, симметричная гормон-ассоциированная алопеция.&#13;
Данные, полученные в настоящей работе, в совокупности с приведенными сведениями из других многочисленных научных источников указывают на необходимость проведения дополнительных исследований для внесения уточнений в инструкции рассматриваемой группы моногормональных препаратов на основе МА в части уточнения максимально возможного срока их применения без ущерба для репродуктивного здоровья животных (18 мес.), а также в отношении определения возможности и сроков для проведения повторного курса.</p>

   <trans-abstract xml:lang="en">
    <p>This study was devoted to an urgent problem in the field of veterinary medicine, namely, the safety of long-term use of a monohormonal drug based on megestrol acetate for cats on the example of Sexcontrol (drops).&#13;
It was found that as a result of the use of Sex Control (drops) in cats, according to the instructions in doses of 2.5 mg per cat per week for 18 months, there is a steady blockage of reproductive function. After discontinuation of the drug for 24 months, there were no signs of resumption of sexual cyclicity. It is likely that Sexcontrol causes profound disturbances in the centers of regulation of sexual function of cats (in the neuroendocrine axis of the hypothalamus-pituitary-gonads), which can be interpreted as severe ovarian dysfunction. It is possible that other centers of neuroendocrine regulation of the body are also affected, which is confirmed by the phenomena observed in experimental animals such as apathy (decreased motor activity, refusal to play, refusal to interact with other cats), prolonged molting, symmetrical hormone-associated alopecia.&#13;
The data obtained in this work, together with the information provided from numerous other scientific sources, indicate the need for additional studies to clarify the instructions of the group of monohormonal drugs based on MA in terms of clarifying the maximum possible duration of their use without prejudice to the reproductive health of animals (18 months), as well as with respect to the definition of opportunities and deadlines for conducting a repeat course.</p>
