THE EFFECT OF NOISE ON FERTILITY OUTCOMES OF WHITE RATS

Mothers and children have long been understood as particularly vulnerable part of society and who deserve more attention. The health of this section of society is an indicator of development. In recent years, stress and emotion have been recognized as causes of some physical, psychological and physiological problems. Noise, as a stressor, has been well know as a serious environmental problem for a large proportion of urban population. This study investigated the effects of noisy environment on polytocous, offspringʹs weight and motherʹs and pubʹs mortality of white rats. Two groups of young female rats were chosen. Control group was kept in a stable environment during fertility and pregnancy, and experimental group in a noisy environment (exposed 8-12 hours per 24 hour). Results showed a significant relationship between noise exposure and pupʹs weight and motherʹs mortality and fertility. The study also showed increasing in polytocous from rats, which were in noisy condition compared to those in quieter environment. Mortality was increased significantly between both mothers and offspring in noisy environment. It seems that noise is a significant environmental factor, which has negative effect both on mothers and offspring. Human-based studies are needed on vegetative effects of noise.
