High power microwave irradiation effects on sperm cells of male rats

The effect of HPM on the intracellular calcium of sperm cells was determined using laser scanning confocal microscopy. The abnormality，micronucleus frequency，livability, numbers and the acrosin reaction of the sperm cells were studied at the same time.The experiments indicate that there are no visible damaging effects on the abnormality and micronucleus frequency of the sperm cells after HPM irradiation,but the acrosin reaction of the rat sperm cells was restrained significantly after 4×105 pulses irradiation. The function of the sperm cells was probably induced by changing the intracytoplasmic calcium concentration of the rat sperm cells.
