Electromagnetic fields carry energy, intensity, and different frequencies, and their biological amplitude effects are so wide. In this regard, the effect of electromagnetic field on testicular tissue and LH and testosterone hormones rates were investigated simultaneously. 60 Syrian mice (30-50 gr) of Balb/C race were randomly divided into control group and attendance group. Control group was not exposed to electromagnetic field and attendance group was exposed to 500 micro-tesla field for 4 hours over a period of 60 days. 20 days after start of experiment 10 mice of both groups were randomly selected and rate of LH and testosterone hormones rates, diameter of lumen, and number of spermatogonia and sperm cells were examined. This method was repeated for other mice after 40 and 60 days of beginning experiment. The experimental data show that amount of LH and testosterone hormones in attendance group increased in 20 and 40 days, but at the end of 60 days decreased in comparison to control group. Number of spermatogonia and sperm cells in attendance group declined over time compared to control group. Lumen diameter in attendance group decreased at 20 and 40 days, but it significantlydecreased at the end of the 60 days compared with control group. Electromagnetic fields can have different effects on testicular tissue and hormones secretion regulator, and the time duration of exposure to electromagnetic fields has an important role.
