No Effects Found
Authors not listed · 2012
Combined CDMA and WCDMA exposure at high levels showed no testicular damage in rats after 12 weeks.
Plain English Summary
Summary written for general audiences
Researchers exposed male rats to combined CDMA and WCDMA cell phone signals for 12 weeks to test effects on sperm production and testosterone. The rats received high-intensity exposure (4.0 W/kg total) for 45 minutes daily, five days per week. The study found no measurable harm to sperm count, hormone levels, or testicular tissue.

}Quick Questions About This Study
This rat study found no effects on sperm count, testosterone levels, or testicular tissue after 12 weeks of combined CDMA and WCDMA exposure at 4.0 W/kg. However, longer-term effects weren't assessed.
The 4.0 W/kg exposure used in this study is about 2.5 times higher than the maximum SAR limit for cell phones (1.6 W/kg in the US), representing unusually intense exposure conditions.
This study tested whether combining CDMA and WCDMA signals would cause additive harm, but found no testicular effects even with the combined 4.0 W/kg exposure over 12 weeks in rats.
Rats received 45 minutes of combined CDMA and WCDMA exposure daily, five days per week, for a total of 12 weeks. This schedule aimed to simulate chronic occupational-level exposure.
Scientists measured sperm count, testosterone levels, oxidative stress markers, cell death indicators, and examined testicular tissue structure. They also tested specific proteins like p53 and HSP70 associated with cellular stress responses.
