Prolonged 3.5 GHz and 24 GHz RF-EMF Exposure Alters Testicular Immune Balance, Apoptotic Gene Expression, and Sperm Function in Rats
This rat study examined 60-day RF-EMF exposure at 3.5 GHz and 24 GHz for 1 or 7 hours per day and assessed testicular cytokines, apoptosis-related gene expression, and sperm quality. The authors report changes consistent with altered immune signaling and pro-apoptotic pathways, alongside reduced sperm parameters (frequency- and duration-dependent). The conclusion frames these findings as an EMF safety concern and suggests longer daily exposure worsened negative effects.
Key points
- Male Sprague Dawley rats were exposed to 3.5 GHz or 24 GHz RF-EMF for 60 days at 1 h/day or 7 h/day with sham controls.
- IL-10 decreased in 24 GHz-exposed groups at both daily exposure durations.
- TNF-α decreased at 24 GHz after 7 h/day exposure.
- At 3.5 GHz (1 h/day), Casp3 increased and Tp53 decreased at the mRNA level.
- Sperm concentration and viability were reduced at 24 GHz with 7 h/day exposure.
- Sperm motility decreased at 3.5 GHz at both 1 h/day and 7 h/day exposures.
- The authors conclude that longer daily exposure increased the severity of negative effects.
