today, due to the advancement of the level of technology, electromagnetic fields (ems) from various industries affect human health. electromagnetic fields generated from microwaves stations and strong electrical devices are considered as a biological pollutant that had attracted to study of their effect on fertility by researchers. among its results, sperm degradation has been reported in humans and animals. the most effect of ems is infertility. the purpose of this study was investigated intensity of different electromagnetic fields on ram sperm viability and motility as animal model.


In a period of six months, ram semen samples were collected by an artificial vagina. samples were placed in electromagnetic device with different intensities including control (0), 1, 1.5, 2, 2.5, 3 and 3.5 m tesla (mt). motility of samples evaluated by a light microscope equipped casa. sample smears were stained with difquick kit, and sperm viability was determined.


The highest motility was intensity of 1 mt and the lowest in 2 mt (85% versus 45%). sperm motility increased in 3 mt and reached 70.6%, then decreased in 3.5 mt and decreased 50.5%. viability in treatments 3 and 3.5 mt reached 76.4% and 85.2% respectively. viability in treatment 2.5 mt was significantly lower than other treatments.


Different intensity of the waves has different behavior on semen and some intensities of emf can be used to increase viability and motility.
