Medical/biological Study (experimental study)

Effects of extremely low-frequency magnetic field on mouse epididymis and deferens ducts. med./biol.

By: Rajaei F, Farokhi M, Ghasemi N, Pahlevan AA
Published in: Iran J Reprod Med 2009; 7 (2): 85 - 89 ( open external web page Journal web site )

Aim of study (according to author)
To study the effect of electromagnetic fields (50 Hz, 0.5 mT) on morphological changes in epididymis and deferens duct in mice.
Background/further details:
30 mice were divided into three groups (exposure, sham exposure and control group outside of the exposure system).

Endpoint

Exposure
General category: magnetic field, low frequency field, 50/60 Hz (AC)

Field characteristicsParameters
50 Hz
exposure duration: continuous for 4 hr/day, 6 days/week for 2 months		magnetic flux density: 0.5 mT

FIELD View further expo parameters

Exposed system:
animal (species/strain): mouse/BALB/c
whole body exposure

Methods
Endpoint/Measurement parameters/Methodology

investigated material: tissue slices (in vitro), isolated organ (in vitro)
investigated organ system: reproductive system

time of investigation: after exposure

Main outcome of study (according to author)
The data showed that the mean diameter of the of epididymis and deferens duct in the exposure group was significantly decreased compared to the outside control group (no difference between the exposure and sham exposure group was found for epididymis diameter, but also for deferens duct). The height of epithelial cells in epididymis and deferens duct in exposed mice was considerably reduced compared to both control groups (significant for deferens duct). In addition, the weight of testes in the exposure group was significantly decreased compared to both control groups.
The authors conclude that the exposure to electromagnetic fields leads to detrimental effects on the male reproductive system in mice as seen by a decrease in diameter of reproductive ducts, a decrease in the height of epithelial cells and weight of testes.
