Research Papers that Mention the Interaction

A significant decrease of estradiol concentrations was observed after 6 months of the melatonin treatment in comparison to initial levels.
Neuro endocrinology letters  •  2002  |  View Paper
Both transdermal and oral estradiol treatment led to an increase as well as decrease of melatonin production in different patients.
International journal of clinical pharmacology and therapeutics  •  1995  |  View Paper
Low baseline estradiol levels in our study population may have hindered the ability to detect any further estradiol-lowering effects of melatonin.
Cancer Causes & Control  •  2012  |  View Paper
Of particular relevance to breast cancer risk, melatonin may also block the estrogen receptor ERalpha and impact the enzyme aromatase, which produces estradiol.

Treatment of the stimulated cells with melatonin counteracted the increase induced by estradiol almost completely.

Furthermore, melatonin decreases circulating levels of estradiol.

Estradiol also inhibited 3H-thymidine incorporation and its effects were additive to those of melatonin.
Suppression of DNA content was observed in cells treated for 2 days with melatonin (0.1 nM); this suppression was maintained for longer periods in the presence than in the absence of estradiol.

Together, these results demonstrate that melatonin interferes with the activation of estrogen receptor by estradiol.

Melatonin correlated negatively with estradiol during the follicular phase (r=-0.5180, p < 0.05) and positively with LH (5 + 0.6321, p < 0.05) in the luteal phase, respectively.
Gynecologic and Obstetric Investigation  •  1998  |  View Paper
The results suggest that the suppression of melatonin secretion in these patients is mediated by GnRH (either directly or indirectly) and/or oestradiol.
