Low frequency electromagnetic fields long-term exposure effects on testicular histology, sperm quality and testosterone levels of male rats.

Published in: Asian Pacific Journal of Reproduction 2015; 4 (3): 195-200

Aim of study (acc. to author)

To investigate the effects of exposure to a 50 Hz magnetic field on the reproductive system of male rats.
Background/further details: Fourteen rats were randomly and equally divided into an exposure and a sham exposure group.

Main outcome of study (acc. to author)

The diameter and the cross sectional area the seminiferous tubules were significantly decreased in exposed rats compared to sham exposed ones, but the number of the seminiferous tubules was significantly increased. Additionally, in exposed rats, the sperm motility and the testosterone level were significantly decreased in comparison to the sham exposed rats.
The authors conclude that exposure to a 50 Hz magnetic field could have an adverse effect on the fertility of male rats.
