Abstract: BACKGROUND & AIM: The current study investigates the effects of rotary strong magnetic field(RSMF) exposure on rats reproductive toxicity, in order to evaluate the safety of RSMF. MATERIAL AND METHODS:In these tests we adopted three dosage groups, that were treated with MF 0.5, 1, 2 h everyday, a negative group and positive group. Then sperm malformation test, traition malformation test and micronucleus test were performed. The growth of rat offspring, G band of chromosome and percent of micronucleus was compared. RESULTS: 0.4 T MF have no toxicity to rat sperm, gravid rat, growth of rat embryo and chromosome. CONCLUSION:0.4 T MF is safe to the reproduction of rat.
