Aim of study (acc. to author)

To study the influence of different powers (3 and 6 W) of 950 MHz electromagnetic fields on testosterone, follicle stimulating hormone and cortisol levels in male rabbits.

Background/further details

18 male rabbits were divided into three groups: sham exposure, 3 W and 6 W exposure.

Endpoint

endocrine changes: serum levels of testosterone, follicle stimulating hormone and cortisol

Exposure

- mobile communications
- mobile phone

Methods Endpoint/measurement parameters/methodology

endocrine changes: serum levels of testosterone, follicle stimulating hormone and cortisol in (radioimmunoassay)

Investigated system:

isolated bio./chem. substance
blood samples

Investigated organ system:

endocrine system

Time of investigation:

after exposure

Main outcome of study (acc. to author)

The results showed a decrease in the concentration of testosterone in both exposure groups (3 and 6 W). In the 6 W group, follicle stimulating hormone concentration increased compared to the 3 W group. No differences in cortisol levels were found in any group.
(Remark EMF-Portal: Data on follicle stimulating hormone are contradictory in abstract, text, and table of this publication, see full text.)
