Objective: To evaluate the effects of long-term exposure to low frequency EMF on the
testicular function and structure.
Methods: Fourteen adult male rats were randomly and equally divided into sham and
experimental groups. Experimental group was exposed to 1 mT, 50 Hz EMF, continuously
for 85 days in a solenoid. Sham group was kept under conditions same as experimental
group, without EMF. At the end of the exposure period, weight and size of testes,
sperm evaluation (sperm counts, motility and viability), histological testicular sections
and serum total testosterone were determined.
Results: Long-term exposure to low frequency EMF significantly decreased the diameter
of the seminiferous tubules and increased number of seminiferous tubules per unit area of
testes. In addition, low frequency EMF significantly reduced sperm motility and testosterone
levels. However, it had no effect on the weight and size of testes, sperm concentration,
and viability.
Conclusions: Prolonged exposure to 50 Hz EMF has an adverse effect on male fertility.
