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

Abstract

Introduction: This research is to investigate different electromagnetic intensity on some
parameters of ram semen and TBARS stress index as an animal model.
Materials & Methods: 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.
Result: The highest motility was at the intensity of 1 mT and the lowest at 2 mT (85%
versus 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 and other
treatments.
Conclusion: The Electromagnetic fields decrease motility and viability.
