Impairment of Oogenesis and Folliculogenesis in Neonatal Rats after Maternal Exposure to Mobile Phones
This animal study examined maternal mobile phone exposure during different gestational windows in Wistar rats and assessed ovarian development and hormones in neonatal offspring. Compared with sham (phone off), exposed groups (standby and conversation/standby) were reported to have lower neonatal estrogen and progesterone and reduced primordial follicle/primary oocyte measures, with stronger effects after longer exposure. The study also reports increased primordial follicle apoptosis, particularly in the conversation/standby condition, and notes effects even with first-week gestational exposure.
Key points
- 54 virgin female Wistar rats were assigned to conversation/standby exposure (n=24), standby exposure (n=24), or sham phone-off (n=6).
- Exposure timing was evaluated by gestational stage (early, mid, late, or all stages).
- Neonatal plasma estrogen and progesterone were reported to be significantly decreased in exposed groups versus sham.
- Primordial follicle and primary oocyte-related measures (counts and size/diameter metrics) were reported to be reduced in exposed groups versus sham.
- The most marked reductions were reported with prolonged exposure across pregnancy.
- Apoptosis of primordial follicles was reported to be increased, especially in the conversation/standby exposure subgroups.
- The authors highlight notable effects during first-week gestational exposure as a new finding.
- The paper frames the results as raising concern about potential fetal fertility risks and calls for further research.
