Study on the quality of semen of radar workers / 解放军医学杂志

ABSTRACT

Objective To study the changes in semen quality and levels of sex reproductive hormones in servicemen constantly exposed to radar. Method The quality of semen was analyzed with the aid of the WlTJ-9000 computer-assisted semen analysis system and the levels of sex hormones were determined with radioimmunoassay in 64 servicemen constantly exposed to radar. Results Compared to control group, semen volume, pH value, sperm density and sperm motility in radar-exposed persons were reduced. No significant difference was observed in semen viscosity, sperm viability rate, morphology, acrosomal integrity rate, and hormone levels between these two groups. Conclusions Microwave non-heating effect had adverse effect on the quality of semen, producing sub-clinical injuries.
