Abstract:: |
Objective To investigate the effects of EMP exposure to male BABL/c mice on the reproduction and its sex ratio. Methods Thirty-three male BALB/c mice were randomly divided into sham-exposed group, 10 000 pulses/d exposed group, and 100 000 pulses/d exposed group with 50 Hz static magnetic field of 35 kV/m for 2 weeks consecutively, then the male mice were mated with unexposed females (1 male vs. 2 female). Mated males were sacrificed to examine the exposure effects on sperm number and testis index after 7 days of mating. The sex ratio of embryos collected from unexposed mated females was investigated by PCR. Results The sex ratio of offspring was 0.298 (14/47) in the 10 000 pulses/d exposed group, significantly lower than 0.871 (27/31) in the sham-exposed group. No statistical changes were observed in the sex ratio of offspring, sperm number, the weights of testis and testis index after 100 000 pulses/d exposure. Conclusions The exposure of male mice to 35 kV/m EMP at 10 000 pulses/d for 2 weeks consecutively may change the sex ratio of mice's offspring. |
