Effects on Hormone Profiles of Long-Term Exposure to Mobile Phones and Base Stations

Researchers at the National Research Centre in Cairo, Egypt, recently published the results of a study on the effects on hormone profiles of long-term exposure to base stations and mobile phones.  The study showed significant decrease in volunteers’ ACTH, cortisol, thyroid hormones, prolactin for young females and testosterone levels.  The study concluded that "greater commitment from policy makers, health care officials and providers is needed to raise public awareness about the hazardous outcomes of long term exposure to RFR (radiofrequency radiation)."

This important study, which became available online on 26 November 2011 may be viewed in its entirety here. (Eskander EF, et al, How does long term exposure to base stations and mobile phones affect human hormone profiles?, Clin Biochem (2011), doi:10.1016/j.clinbiochem.2011.11.006)
Thank you to the Citizens for Safer Technology Organization for the following summary:

Article in Press from Clinical Biochemistry Journal Introdction:

"Because of the increase in the usage of wireless communication devices of mobile phones in recent years, there is an anxious concern on the possible hazardous effects of prolonged exposure to radiofrequency radiation (RFR). In considering the biological effects of RFR, the intensity and frequency of the radiation and exposure duration are important determinants of the responses. 

"It has been reported that exposure to RFR could affect the nervous system. Hardell et al. found that cell phone users had an increased risk of malignant gliomas. Subjecting human spermatozoa to RFR showed decrease in sperms motility and vitality and increase in DNA fragmentation. The authors hypothesize that the high sporadic incidence of the clinical symptoms of the autoimmune multiple Sclerosis disease may be a result of long exposure to RFR from mobiles. 

"This study is concerned with assessing the effect of RFR emitted from mobile phones and base stations on human hormone profiles, with anticipation to offer recommendations to assure health care and safety for humans continuously exposed to radio frequency radiation.”

Under “Discussion”, the study concludes:

“The intensity and frequency of RFR and exposure duration are important determinants of the cumulative effect that could occur and lead to an eventual breakdown of homeostasis and adverse health consequences. Therefore, greater commitment from policy makers, health care officials and providers is needed to raise public awareness about the hazardous outcomes of long term exposure to RFR.  As mentioned in our results, persons who were exposed to RFR suffered significant decreases in their ACTH and cortisol levels as compared to controls…

"... the present study revealed that high RFR emitted from either mobile phone or base station has tangible effects on pituitary–adrenal axis represented in the reduction of ACTH and consequently cortisol levels. Also, exposure to RFR is associated with decrease in the release of thyroid hormones. Moreover, our data suggested that each of serum prolactin in young females, and testosterone levels in males significantly dropped due to long-term exposure to RFR. Conversely, the serum prolactin levels for the adult females significantly rose with increasing exposure time. Finally, the degenerative effects of exposure to RFR were more pronounced for persons who used mobile phones for long periods of 6 years. Also, the effect of this type of radiation was more obvious for persons living nearby base stations and exposed for a period of 6 years."


  1. I've been surfing on-line greater than three hours lately, yet I by no means discovered any interesting article like yours. It is pretty value sufficient for me. In my view, if all webmasters and bloggers made excellent content as you did, the net will probably be much more helpful than ever before.

    1. Thank you. Your website is interesting, however as someone having been treated for breast cancer, I am wary of such remedies. I'd be interested to hear your views on the subject or maybe you could direct me to some articles.
