Long-term exposure of male and female mice to 50 Hz magnetic field: effects on fertility. med./bio.

Published in: Bioelectromagnetics 2002; 23 (2): 168-172

Aim of study (acc. to author)

To investigate the effects of a 90 day ELF magnetic field (MF) exposure on fertility of mice.

Background/further details

In a first experiment, body weight and weight of reproductive organs were determined post mortem after 90 days of exposure. In a second experiment, male and femal mice, 60 days of age, were separately exposed for 90 days to 50 Hz/25 µT magnetic field. After exposure, each exposed male was individually mated with two unexposed virgin females. Each exposed female was mated with one unexposed male. After a 10 day mating period, females were examined for fertility.

Main outcome of study (acc. to author)

No effects on the fertility of male or female mice could be demonstrated. Also, no alteration neither in body weight nor in organ weight in males could be found. Only ovarian weight was significantly increased in exposed female mice.
The results of this study suggest that magnetic field exposure had no adverse effect on fertility of mice.
