Other Studies - Hormone Studies

Some studies have examined the effect of radiofrequency radiation on the excretion of 6-hydroxymelatonin (6-OHMS) in laboratory animals. This substance is the main metabolic end product of melatonin, a hormone secreted by the pineal gland that has anticancer effects. Most of the studies did not show altered excretion of 6-OHMS as a result of the RF exposure. Sukhotina (2006) found alterations in melatonin secretion when isolated pineal glands from hamsters were exposed to 1800 MHz RFR.

Black and Heynick (2003) reviewed research in this area and concluded that there is no evidence that RF radiation affects hormonal function, other than in doses sufficient to cause heating.
