Effects of extremely low frequency magnetic field on fertility of adult male and female rats. med./bio.

Published in: Bioelectromagnetics 2001; 22 (5): 340-344

Aim of study (acc. to author)

To investigate the effects of a 90 day extremely low frequency magnetic field exposure on fertility of rats.

Background/further details

Male and femal rats, 20 weeks of age, were separately exposed for 90 days to 50 Hz (23-27 µT) magnetic field. After exposure each exposed male were individually mated with two unexposed virgin females. Each exposed femal was mated with one unexposed male. After a 10 day mating period, females were examined for fertility.
