| The biological effects of ELF EMF exposure is the emphasis of the study of biological physics community, in recent years, in the field of biomedical engineering, the researchers used extremely low frequency electromagnetic irradiation field rodents that was caused by toxic interference with access to a large number of experimental results. Effect of ELF-EMF interference, which cause toxic effects in the reproductive system of rodents has caused widespread concern, studies have found that mice F exposure to ELF-EMF, reproductive system development during adverse impact. But after thousands of years of natural selection, its ability to adapt is very strong, once to adapt to a single frequency and field strength of the magnetic field after irradiation difficult to have good results.This paper presents a new experimental method, using a new radiation source, positioning the mice abdomen reproductive system for electromagnetic biological target, aiming to solve the rodent strong ability to adapt to the rodents at a loss for the above and to drive the rodent results. This source will be several good rodent effects of extremely low frequency composite electromagnetic field and the direction of extremely low frequency electromagnetic fields can be changed.Mouse spermatogenic cells disorganized, cell number decreased, spermatogenic cell atrophy. Epididymis in sperm maturation rate, decreased sperm viability, severe epididymal sperm appear.Derangement of mouse spermatogenic cells, reduced cell layers of spermatogenic cells in testis cellcycle arrest and irradiation cause damage to the mouse testis, scarred sperm in the testis into the epididymis, continue to be subject to the epididy misirradiation affect sperm maturation rate decreased, reduced sperm viability, irradiation caused a serious decline in the quality of mouse sperm.The effect on male reproductive system toxicity in mice is obvious. |
