Effects of infrasound on sperm quality and tissue antioxidant system in testes of rats / 中国病理生理杂志

ABSTRACT

AIM:To observe the effects of infrasound on sperm quality and explore some underlying mechanisms. METHODS: Adult male SD rats were exposed to infrasound of 8 Hz at 90 dB or 130 dB for 1,7,14 or 21 d(2 h/d), whose epididymises were obtained for sperm count, abnormity and activity ratio inspection and whose testes for GSH-Px and MDA inspection. RESULTS: With prolonged exposure, sperm quality and GSH-Px in 90 dB and 130 dB groups decreased, while MDA increased, and at the same time point, the indexes of 130 dB groups changed more profoundly than those in 90 dB groups. CONCLUSION: Biological effect of infrasound on testes depends on the exposure parameters. The mechanisms of which could be unbalanced antioxidant system induced by infrasonic exposure.
