Male Reproductive and Cellular Damage After Prenatal 3.5 GHz Radiation Exposure: One-Year Postnatal Effects
This animal study examined whether prenatal exposure to 3.5 GHz radiofrequency radiation (2 hours/day) affects male reproductive outcomes later in life. Male rat offspring assessed at 12 months showed multiple adverse testicular and cellular findings in exposed groups versus sham controls, including impaired spermatogenesis markers, increased abnormal sperm morphology, increased DNA damage, and increased apoptosis, with full-gestation exposure generally most pronounced. The authors interpret the results as evidence of persistent reproductive toxicity from prenatal exposure and call for further mechanistic work and precautionary actions.
Key points
- Pregnant rats were assigned to sham, full-gestation (3T) RFR, or late-gestation (2T) RFR exposure groups with 2 hours/day exposure.
- Adult male offspring (12 months) from the full-gestation exposure group had reduced seminiferous tubule diameter and epithelial height versus controls.
- Johnsen scores were lower in the full-gestation exposure group, consistent with impaired spermatogenesis.
- Abnormal sperm morphology was higher in exposed offspring compared with controls.
- γ-H2AX immunostaining was elevated in both exposure groups, indicating increased DNA damage.
- Beclin-1 expression was higher in the full-gestation exposure group, suggesting increased autophagy.
- Apoptosis measures (TUNEL-positive cells and apoptosis index) were higher in exposed groups than in sham controls.
- The abstract notes no postnatal EMR exposure for a year, yet differences were still observed at 12 months.
