Chronic Exposure Duration and Frequency Variation on Selected Fertility Indices of Male Wistar Rats Exposed to Mobile Phone Electromagnetic Radiation

CI Iheme1

The chronic effects of exposure duration and different frequencies
of electromagnetic radiations from mobile phones on selected
fertility indices of male wistar rats were studied. Sixty
(60) rats used for the study were randomly divided into two
major groups (A and B) of thirty (30) rats each, and subdivided
into I-VI of five rats each according to their weights. Groups
A and B were exposed for 90 and 180days respectively. Rats
in sub-groups I, II, III and VI were exposed to 900MHz for 5,
10, 15 and 0 Hrs/day respectively, while the rats in subgroup
IV were exposed to 2.4GHz for 24hrs/day, and sub-group V
served as the normal control. At the end of 90 and 180 days,
the rats were anaesthetized; the testes, sperm and blood samples
were collected. The values: 13.34±1.56 and 47.88±2.56 of
Total Abnormal Sperm cells (TAS) from group IVA and IVB,
showed significant (p<0.05) increase when compared to the
controls:5.70±0.21 and 6.73±0.52, and other subgroups. SOD,
CAT and MDA from group IVB were positively correlated (p<
0.05, r= 0.890, r= 0.866, r= 0.953) to TAS respectively. Sperm
count, sperm motility and total sperm morphology indices
from group IVA and IVB, showed significant (p<0.05) reductions
when compared to the control, and other subgroups.
From our findings, it can be concluded that electromagnetic
radiation from mobile phone negatively affected fertility indices,
and the effects of which were proportional to exposure durations
and frequencies.
