AUTHORS' ABSTRACT: Mugunthan et al. 2016 (IEEE #6559): Objective: The aim of our study was to evaluate possible effects of chronic exposure to 900 - 1900 MHz radiations emitted
from 2G cell phone on the testis of mice at the histological level. Methods: Mice were exposed to 2G ultra-high frequency radiation, 48
minutes per day for a period of 30 to 180 days. The amount of electromagnetic field (EMF) exposed was calculated by the radiation
frequency meter. The sham control mice were exposed to similar conditions without 2G exposure. Each animals weight was recorded
before sacrifice. Three animals each were sacrificed at the end of 30, 60, 90,120,150 and 180 days of exposure in the experimental
group after 24 hours of last exposure. Same numbers of control animals were sacrificed on similar period. We collected blood samples
to measure plasma testosterone. We measured and analyzed the size, weight and volume of the testis. Testis sections were analyzed
under the light microscope for structural changes. Results: In 2G exposed group animal weight was lower at first, second and fourth
month (p value d0.05). The mean testis weight of 2G exposed mice was significantly reduced in all months except fourth month (p value
<0.05) and the mean testis volume was significantly reduced in the first three months (p value 0.02).The mean seminiferous tubule
density per unit area was significantly lower (p value <0.001) in the 2G exposed testis. The mean seminiferous tubule diameter was
significantly reduced in 2G exposed testis (p value is highly significant <0.001) except the second month. The mean number of Sertoli
cells and Leydig cells were significantly reduced in 2G radiation exposed mice (p value is highly significant <0.001). While compared
with control group, mean serum testosterone level of 2G exposed mice were significantly lower (p value 0.004). The following
microscopic changes were found in the testis of 2G cell phone radiation exposed mice. 1. The interstitium appeared wide 2. Sertoli cells
and spermatogonia were detached from the basal lamina. 3. Vacuolar degeneration and desquamation of seminiferous epithelium. Most
of the peripheral tubules showed maturation arrest in the spermatogenesis. Seminiferous tubules scored between 8 and 9 using Johnson
testicular biopsy score count. Conclusion: Chronic exposure to ultra-high frequency radiation emitted from a 2G cell phone could cause
microscopic changes in the seminiferous tubules, reduction in the number of Sertoli and Leydig cells and decreased serum testosterone
level. Long term use of cell phones could cause male infertility. |
