Melatonin in Reproductive Medicine: A Promising Therapeutic Target?

ABSTRACT

Melatonin, mainly released from the pineal gland, also produced in the reproductive organs and cells, plays important roles in rhythms of the sleep-wake cycle, retardation of ageing processes, and antioxidant/anti-inflammatory functions. As a key mediator in reproductive systems, melatonin is participated in the reproductive process via regulating gamete and embryo development and influences reproductive diseases and pregnancy outcomes. The underlying mechanisms include epigenetic and other regulations, which are interesting for exploring new targets in the prevention and treatment of reproductive diseases. This review discusses the relationship between melatonin and reproductive functions and dysfunction, as well as potential clinical applications of melatonin in reproductive medicine. Notably, Developmental Origins of Health and Diseases (DOHaD) is closely linked to reproduction, this article is the first to review the new progress in studies on the possible relationship between melatonin and DOHaD.
