title: Effects of extremely low frequency electromagnetic fields on testes in guinea pig.
abstract: This study is carried out to measure the changes in testosterone hormone level and changes in testes tissue on 36 adult male Guinea pigs that divided to 6 groups. Group A as control group exposed to nil Electromagnetic Field (EMF) for two hours per day for 5 days duration, group B exposed to 0.013 microT in 5 Hz to the Same duration period, group C exposed to 0.207 microT in 50 Hz in similar conditions, group D exposed for 4 h day(-1) for 5 days in 0.013 microT, group E tested in 0.207 microT as group D, group F used as controlled group exposed for four hours per day in nil electromagnetic field. Guinea pig blood was tested after 5 days. Then data analyzed by t-test. The results indicated a significantly difference between control group and tested group of four and two hours, testosterone level decreased (p < 0.001), also testes tissues were sampled and observed main tissue changes in some treatments.
