GSM radiocellular telephones do not disturb the secretion of antepituitary hormones in humans.

View Original AbstractOne month of typical cell phone use didn't permanently alter hormone levels in healthy men, though temporary thyroid changes occurred.
Plain English Summary
French researchers exposed 20 healthy men to cell phone radiation for 2 hours daily over one month and measured six key hormones produced by the pituitary gland. They found no lasting changes in hormone levels, with only a temporary 21% decrease in thyroid-stimulating hormone that returned to normal after exposure ended. This suggests that typical cell phone use doesn't cause permanent disruption to the body's hormone control center.
Study Details
An experiment was designed to evaluate the effect of a 900 MHz RF radiation emitted by a Global System for Mobile radiotelephone (217 Hz impulses, one-eighth duty cycle, 2 W peak power) on human endocrine functions.
Twenty healthy male volunteers aged from 19 to 40 were inducted in the present experiment. Each subj...
Results indicated that all hormone concentrations remained within normal physiologic ranges. A diffe...
Because this change recovered fully during the postexposure period, it is concluded that 1 month of intermittent exposures to RF radiation from a cellular telephone does not induce a long-lasting or cumulative effect on the hormone secretion rate of the anterior pituitary gland in humans.
