Long-term 700MHz 5G exposure caused ovarian tissue damage and oxidative stress in female rats.

Plain English Summary

Summary written for general audiences

Researchers exposed female rats to 700MHz 5G radiation for either 10 days (6 hours daily) or 60 days (4 hours daily) to study reproductive effects. While hormone levels and fertility cycles remained mostly normal, long-term exposure caused oxidative stress in ovaries and tissue changes including cystic follicles. The findings suggest prolonged 5G exposure may harm reproductive organs through cellular damage.

Quick Questions About This Study

No, the study found that both short-term (10 days) and long-term (60 days) exposure to 700MHz 5G radiation did not disrupt estrous cycles in female rats. Normal reproductive cycling continued despite daily radiation exposure.
Yes, long-term exposure to 700MHz 5G radiation for 60 days caused visible ovarian tissue changes including cystic follicles and abnormal blood vessels. However, 10 days of exposure showed no tissue damage.
Yes, female rats exposed to 700MHz radiation showed slightly but significantly elevated testosterone levels compared to unexposed controls, while estradiol and progesterone remained normal. This hormonal shift occurred in both exposure groups.
Exposed ovaries showed increased malondialdehyde (cellular damage marker) and decreased superoxide dismutase, sulfhydryl content, and antioxidant power. These changes indicate the body's antioxidant defenses were overwhelmed by radiation-induced oxidative stress.
Researchers tested two exposure schedules: 6 hours daily for 10 days (short-term) and 4 hours daily for 60 days (long-term). The longer duration caused more significant tissue and biochemical changes.
