بررسی اثر آلودگی صوتی بر هورمون های محور هیپوفیز-گناد در موش صحرایی نر

Background : Noise is a kind of environmental pollution affecting the life of humans. Many researches have been carried out on the effects of noise stress on the different parts of body, but few studies have been done on sexual systems. The aim of this study is to investigate the effects of noise stress on testosterone, LH and FSH. Materials and Methods: Two groups of ten male rats have been introduced to 2 noisy environments of experimental and ordinary (with intensity of 90-120 decibel and frequency of 300-350 HZ) for fifty days from 7 am to 7 pm. After 50 days blood samples were collected from tail and level of testosterone, LH and FSH measured by Eliza and results were interpreted using T test with a significance of p<0.05. Results: Statistical studies showed that the average of testosterone secretion, LH and FSH in comparison with control group, had a significant difference (p<0.05). Conclusion: On the whole it can be said that sonic stresses decrease the level of testosterone, LH and FSH.
