Influence of Electromagnetic Fields Emitted by GSM-900 Cellular Telephones on the Circadian Patterns of Gonadal, Adrenal and Pituitary Hormones in Men.

View Original AbstractCell phone radiation temporarily reduced key hormones by up to 28% in healthy men, raising questions about long-term cumulative effects.
Plain English Summary
French researchers exposed 20 healthy men to 900 MHz cell phone radiation for 2 hours daily over 4 weeks and measured their hormone levels around the clock. They found temporary decreases in growth hormone (28%) and cortisol (12%) during exposure, but these changes disappeared after stopping exposure and all hormone levels stayed within normal ranges. The study suggests that typical cell phone use may cause minor, reversible changes to certain hormones but doesn't disrupt the body's overall hormone system.
Study Details
The present study investigated the effect of exposure to 900 MHz GSM radiofrequency radiation on steroid (cortisol and testosterone) and pituitary (thyroid-stimulating hormone, growth hormone, prolactin and adrenocorticotropin) hormone levels in 20 healthy male volunteers
Each subject was exposed to RF EMFs through the use of a cellular phone for 2 h/day, 5 days/ week, f...
All hormone concentrations remained within normal physiological ranges. The circadian profiles of pr...
Our data show that the 900 MHz EMF exposure, at least under our experimental conditions, does not appear to affect endocrine functions in men.
