The pineal gland, through its hormone melatonin, is involved in the mechanisms that regulate the aging process involved in the onset of menopause. Considering the melatonin changes reported during pre-, peri-, and postmenopause, an influence of melatonin on the hormonal changes associated with menopause transition could be expected.
We report the first longitudinal case study, covering a 7.5-year period, on the effects of melatonin administration on the reproductive hormones luteinizing hormone, follicle-stimulating hormone, and 17β-estradiol during that period of the reproductive life.
The data obtained in this case report show that melatonin administration was able to delay the characteristic endocrine changes that occur during the course of menopause.
The data obtained in this case report show for the first time that melatonin was able to delay the characteristic endocrine parameters associated with menopause onset.
