This in vitro study exposed newborn rat calvarial osteoblasts to 50 Hz sinusoidal electromagnetic fields at 1.8 mT for different daily exposure times (0.5–3.0 h). The authors report inhibited osteoblast proliferation at longer exposure times, alongside increased differentiation markers (ALP activity) and…

This animal study exposed 36 adult male guinea pigs to extremely low frequency electromagnetic fields at 5 Hz or 50 Hz and compared testosterone and testes tissue outcomes with sham/control conditions. After 5 days, the authors report a significant decrease in testosterone in exposed groups versus controls. They also…

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…

Jan 1, 2007
This in vitro study examined whether continuous extremely low-frequency electromagnetic fields (3 Hz, 4 mT for 3 hours) alter protein expression in human fibroblast cells using proteomics. The authors report that some protein expressions differed between exposed and sham cells. They identify reduced expression (about…
