Effect of different intensities of electromagnetic field on some parameters and stress index in semen Lori Bakhtiari ram

Electromagnetic fields and radio frequency radiation interact in human body tissues and can have effects on reproduction and the most mentioned side effects of the impact waves is in the enzyme reproductive system, male sex hormones, bone marrow, heart rate, hematological changes and neurobehavioral disorders.. This research is to investigate different electromagnetic intensity on some parameters of ram semen and TBARS stress index as an animal model. After semen collection with the help of an artificial vagina, samples were placed in a device that produces electromagnetic waves with different intensities, including control, 1, 1.5, 2, 2.5, 3, and 3.5 millitesla (mT). The Semen parameters were evaluated with a microscope equipped with a computer, Computer Assisted Sperm Analysis (CASA). The sperm viability was determined by Dif Quick kit. The highest motility was at the intensity of 1 mT and the lowest at 2 mT (85% vs 45.5%). The sperm motility increased at 3 mT and reached 74%, but then decreased significantly at 3.5 mT intensity and reached 50.5%. The Sperm viability in 3 and 3.5 mT reached 76.4 and 85.2% respectively. There was a significant decrease in viability at the intensity of 2.5 mT compared to other treatments. The concentration of TBARS significantly decreased at the intensity of 3 mT compared to the control group and other treatments. The dissimilar intensities create different effects. It is possible to get help some intensity in sterility treatment.
