Abstract

Abstract:

The present work focused on the cumulative damage caused by periodically repeated wide-band electromagnetic pulses. The exposure protocol was as follows: electric field intensity E=110 kV/m, 297 kV/m, and 873 kV/m; pulse number N=5, and 100; exposure was repeated 2 times per day, for 2 weeks. 6 h, 1 d, 3 d, 7 d, and 10 d after exposure, the testosterone concentration in blood plasma, superoxide dismutase (SOD) and malondialdehyde (MDA) in the testis, and acrosin activity of sperms were determined by ELISA. The apoptosis rate of spermatogenic cells in the testis was studied by TUNEL, and the survival rate of sperms in the epididymis by CASA. The results showed that compared with single exposure, 28 periodic exposures exhibited a cumulative damaging effect on the reproductive system of male rats. The cumulative effect increased significantly with increasing E and N. Similar to single exposure, the damage caused by repetitive exposure was gradually recovered to a certain degree with prolongation of exposure time.
