Relationship between exposure to Extremely Low-Frequency (ELF) magnetic field and the level of some reproductive hormones among power plant workers. epidem.

Published in: J Occup Health 2020; 62 (1): e12173

Aim of study (acc. to author)

A cross-sectional study was conducted in Iran to investigate the relationship between occupational exposure to extremely low frequency magnetic field and the level of reproductive hormones in male power plant workers.

Further details

The general health of the participants was assessed using the Goldberg and Hiller's 28-item scaled version of the General Health Questionnaire.
A blood sample was taken from each participant to analyze hormone levels.

Conclusion (acc. to author)

No statistically significant correlation between the level of exposure to extremely low frequency magnetic fields and serum levels of testosterone, luteinizing hormone and follicle stimulating hormone in male power plant workers was found.
The authors concluded that there was no relationship between occupational exposure to extremely low frequency magnetic field and the level of reproductive hormones in male power plant workers.
