Effects of pulse microwave on reproductive system of male rat and its offspring

The effect of pulse microwave irradiation on the reproductive system of animal and human as well as their offspring is a critical issue that causes interests. In present work, the parental rats were exposed to 2.71 GHz pulses microwave (field strength 48 kV/m, pulse width 750 ns, pulse number 2001, 20010, 20020, respectively), and the DNA damage during the spermatogenesis process, the sperm motility, the growth of the baby offspring, and the learning and memory ability of the adult offspring were studied by means of DNA staining, TUNEL staining, Elisa assay, sperm motility CASA detection, and water maze experiment. The experimental results show that the single irradiation on male rats affects their early spermatogenesis process rather than the sperm motility, while multi-times of irradiation decrease the sperm motility due to the accumulative effect. The growth of baby offspring is temporarily blocked, and the learning and memory ability also trends to be blocked when the parent rats receive the irradiation.
