Effects of Exposure to Cellular Phones 950 MHZ Electromagnetic Fields on Progesterone, Cortisol and Glucose Level in Female Hamsters (Mesocricetus auratus) med./bio.

Published in: Asian J Anim Vet Adv 2011; 6 (11): 1084-1088

Aim of study (acc. to author)

To investigate the effects of exposure to cellular phones electromagnetic fields on progesterone, cortisol and glucose levels in female hamsters.

Background/further details

72 adult, non-pregnant female golden hamsters were divided into three groups: control group, short-term exposure group (for 10 days), and long-term exposure group (for 60 days).



Exposure Parameters
Exposure 1: 950 MHz
Exposure duration: continuous for 3 h/day for 10 or 50/60 days

General information

animals divided into three groups: - long term exposure group (50/60 days) - short term exposure group (10 days) - control group there are many inconsistencies in this article: - although the title suggests a frequency of 950 MHz, the article sometimes refers to 900 MHz - it is not clear, if the long term exposure was 50 or 60 days (both values used in article) - an SAR value of 0.6 week/kg is given (probably 0.6 W/kg is meant)

Main outcome of study (acc. to author)

A statistically significant decrease in the progesterone level and a significant increase in the cortisol level was observed in both exposed groups (short-term and long-term) compared to the control group. The glucose level of the long-term exposed group was significantly increased in comparison to the short-term exposed group and the control group.
