Plain English Summary
Turkish researchers exposed young male rats to cell phone frequencies (900 MHz and 1800 MHz) for 2 hours daily over 90 days to study effects on reproductive development. They found that EMF exposure increased testosterone levels and accelerated sperm development compared to unexposed rats. The researchers concluded this electromagnetic exposure may trigger early puberty in developing males.
Why This Matters
This study adds to growing concerns about EMF exposure during critical developmental periods. While the researchers framed their findings as potentially positive effects on sperm quality, the real concern is what they identified as 'precocious puberty' - essentially, electromagnetic radiation artificially accelerating sexual development in young mammals. The frequencies used (900 MHz and 1800 MHz) are identical to those used by 2G and 3G cell phones, making this directly relevant to human exposure patterns. What makes this particularly significant is the timing - the rats were exposed from just 2 days old, mimicking how children today are exposed to wireless radiation from infancy. The science demonstrates that developing reproductive systems are especially vulnerable to EMF interference, and artificially accelerated development is not necessarily beneficial for long-term health outcomes.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 1.8/0.9 GHz Duration: 2 h per day for 90 days
Study Details
The aim of our study was to evaluate the possible effects of whole-body electromagnetic field (EMF) exposure on reproduction in growing male rats.

In conclusion, the present study indicated that exposure to electromagnetic wave caused an increase in testosterone level, epididymal sperm motility (forward), and normal sperm morphology of rats. As a consequences, 1800 and 900 MHz EMF could be considered to be a cause of precocious puberty in growing rats.
