Abstract: 

Considering the life is affected by natural electromagnetic fields and artificial electromagnetic fields have been developed and are further being developed in recent decades, this research has been done on the effects of 0.06mT intensities with 50HZ frequency in gonads and sex hormone of adult male NMRI mice. Uniform electromagnetic fields were produced using solenoid coils To do so, two experimental groups (n=12) were exposed to electromagnetic wave for 28 days four hours a day.  The results of experimental groups were compared with control sham groups (n=6) and (n=6). The gonads were extracted from the mouse body and cross sectional and coloring procedures were accomplished for more histological studies. Besides, the amount of FSH, LH, Testosterone hormones was measured using Gamma counter method. Electromagnetic investigation of gonads and sex hormones showed significant decrease of diameter and weight of gonads and number of seminiferus tubuls and decrease of spermatid ,spermatozoa and testosterone (p<0.05) in 0.06 mT electromagnetic field compared with sham control groups. The tunica albuginea thickness and LH increased at the same field significantly. Mean value of leydig cell, sertoli cell, spermatogon and spermatocyt and FSH in different groups did not show significant change. Results of this research showed electromagnetic field could affect the gonads and sex hormones.
