Аннотация

Среди пар, неспособных зачать ребенка, бесплодие частично или полностью объясняется мужским фактором примерно в 50% случаев. При рутинном обследовании этиология мужского бесплодия остается неопределенной у 30–50% пациентов. Одним из частых этиологических факторов мужского бесплодия является окислительный стресс, который фактически представляет собой дисбаланс между выработкой активных форм кислорода и механизмами антиоксидантной защиты организма. Сегодня предложен термин «мужское бесплодие, обусловленное окислительным стрессом» (male oxidative stress infertility) как новый дескриптор для бесплодных мужчин с сочетанием аномальных характеристик спермы и окислительного стресса. В этой связи наряду с использованием традиционных антиоксидантов необходим поиск новых молекул для борьбы с окислительным стрессом у бесплодных мужчин. Перспективной стратегией выглядит использование в качестве антиоксиданта мелатонина – гормона, секретируемого шишковидной железой.
В обзоре рассмотрены антиоксидантные эффекты метаболического каскада мелатонина. Приведены результаты иследований, доказывающих связь между уровнем мелатонина в семенной плазме и мужской фертильностью. Представлены новые научные данные, касающиеся защитного потенциала мелатонина против окислительного стресса, вызванного различными метаболическими нарушениями, противораковой химио- и лучевой терапией и другими патогенетическими состояниями и негативными воздействиями. Проанализированы исследования, результаты которых демонстрируют перспективы использования мелатонина для защиты сперматозоидов от окислительного повреждения при реализации вспомогательных репродуктивных технологий. Подведены промежуточные итоги исследований, посвященных возможности применения мелатонина в качестве пищевой добавки у инфертильных мужчин.

Abstract

Among couples unable to conceive a child, infertility is explained by the male factor in about 50% of cases. The etiology of male infertility remains uncertain in 30-50% of patients. One of the frequent etiological factors of male infertility is oxidative stress, a status in which an unbalance between the production of reactive oxygen species and the mechanisms of antioxidant protection. Today, the term «male oxidative stress infertility» has been proposed as a new descriptor for infertile men with a combination of abnormal sperm characteristics and oxidative stress. Along with the use of traditional antioxidants, it is necessary to search for new molecules to combat oxidative stress in infertile men. A promising strategy is to use melatonin, a hormone secreted by the pineal gland, as an antioxidant.
The review examines the antioxidant effects of the melatonin metabolic cascade. The results of studies on the relationship between the level of melatonin in seminal plasma and male fertility are presented. New scientific data on the protective potential of melatonin against oxidative stress caused by various metabolic disorders, anticancer chemo- and radiation therapy and other pathogenetic conditions and negative effects are presented. The research on the prospects of using melatonin to protect spermatozoa from oxidative damage in the implementation of assisted reproductive technologies is analyzed. The interim results of studies on the possibility of using melatonin as a dietary supplement in infertile men are summarized.
