[Long-term exposure to low intensity microwave radiation affects male reproductivity].

Abstract

OBJECTIVE: To evaluate the effect of Long-term exposure to low intensity microwave radiation on male reproductivity. METHODS: A total of 289 married male radar operators were included in the radar group and 148 married men unexposed to microwave radiation were enrolled as controls. Questionnaires were used and the intensity of microwave radiation in different working areas was detected. RESULTS: The rate of sexual dysfunction was 43.6% in the radar group and 24.4% in the control group (P < 0.01). The natural pregnancy rate was 53.6% within 1 year of marriage and 46.4% after 1 year of marriage in the radar group, as compared with 81.1% and 18.9% in the control group (P < 0.01). CONCLUSION: Long-term exposure to low intensity microwave radiation evidently increased the sexual dysfunction rate and decreased natural pregnancy rate in men.

Main findings

Sexual dysfunction was reported more often in radar operators (43.6%) than controls (24.4%) (P < 0.01). Natural pregnancy rates differed between groups: in the radar group 53.6% occurred within 1 year of marriage and 46.4% after 1 year, versus 81.1% and 18.9% in controls (P < 0.01). The authors conclude long-term low-intensity microwave exposure increased sexual dysfunction and decreased natural pregnancy rate.

Outcomes measured

• sexual dysfunction rate
• natural pregnancy rate (within 1 year of marriage; after 1 year of marriage)

Limitations

• Exposure frequency and quantitative exposure metrics beyond 'intensity in different working areas' not reported in abstract
• Outcomes appear questionnaire-based; objective clinical measures not described
• Potential confounding factors and adjustment methods not described
• Study design details (e.g., matching, follow-up period) not described

Suggested hubs

• occupational-exposure (0.9)
  Study compares radar operators with unexposed controls for reproductive outcomes under occupational microwave exposure.
