Exposure duration: continuous for 30 min/day during 3 months (group 1) or continuous for 60 min/day during 3 months (group 2)
No parameters are specified for this exposure.
Mobile phone exposure for 60 minutes/day caused hypospermatogenesis and maturation arrest in the testis of the three rats (18.75%) compared to the control group. However, no abnormal findings were found in rats that were exposed for 30 minutes/day for a total period of three months.
The authors conclude that long-term exposure to mobile phone irradiation can cause hypospermatogenesis and maturation arrest in the spermatozoa in the testis of Wistar albino rats.
