Melatonin is a hormone secreted by the pineal gland of the brain, belonging to the indole heterocyclic compounds. Its chemical name is N-acetyl-5-methoxytryptamine. It is usually secreted at night and has a clear circadian rhythm. It can inhibit the hypothalamic pituitary gonadal axis, reduce the levels of gonadotropins, luteinizing hormone, and follicle stimulating hormone, and directly act on the gonads, reducing the levels of androgens, estrogen, and progesterone. Melatonin can also eliminate free radicals, resist oxidation, and inhibit lipid peroxidation, protect cell structure, prevent DNA damage, reduce the content of peroxides in the body, and improve sleep.
