A cross-sectional study on nonionizing radiation to male fertility / 中华流行病学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between microwave radiation and male reproductivity.</p><p><b>METHODS</b>After filling out questionnaire and body check, we carried out molecular epidemiological studies, using single cell gel electrophoresis (SCGE) and sperm automatic analysis among people working on radar.</p><p><b>RESULTS</b>Quality of semen and semi-clinical injury of sperm among the people working on radar had changed when radar electromagnetic wave frequency distance, intensity, lasting time and protection shield were changing. Dose-response relationship was noticed and the increase of sperm dysmorphia played a principal role. The results between exposed group and control group showed significant difference (P < 0.01).</p><p><b>CONCLUSION</b>People working on radar who suffered from non-ionization for long time and had bad radar shield protection would show semi-clinical injury on sperm and bad semen quality. However, it did not affect the male reproductive function. It was necessary to reinforce the protection of non-ionization and to improve male reproductive health care of people working on radar.</p>
