[Female genital toxicities of high-frequency electromagnetic field on rats].
This rat study examined sub-chronic exposure to a 30 MHz electromagnetic field at 0–1600 V/m for 8 hours/day, 5 days/week, over 56 days. The authors report no change in ovarian wet weight, but dose-related changes in estrous cycle timing, reproductive hormones (higher LH and lower E2 at higher exposures), and ovarian follicle composition. Ovarian ultrastructure reportedly appeared more abnormal with increasing exposure level, and the authors conclude HF-EMF exposure is associated with female gonadal toxicities in this model.
Key points
- Sixty adult female Wistar rats were assigned to five exposure groups (0, 25, 100, 400, 1600 V/m) at 30 MHz.
- Ovarian wet weight and organ coefficient were reported as not significantly different from controls.
- Proestrus duration decreased in the 100, 400, and 1600 V/m groups compared with controls.
- Anestrum duration increased in the 400 and 1600 V/m groups compared with controls.
- Serum LH increased and serum estradiol (E2) decreased in the 400 and 1600 V/m groups.
- Ovarian histology showed increased atretic follicles and reduced mature and primary/secondary follicle ratios at higher exposure levels.
- Electron microscopy findings were described as increasingly abnormal with higher exposure dose.
