harmful physiological, psychological and morphological outcomes to the body.
So this study was conducted in order to investigate the effects of noise stress
on the parenchyma of testis. Healthy mature females rats (n = 20) were mated
with the mature male rats and then randomly allocated equally either to experimental
or control groups. Experimental group has given daily noise stress up to birth
their child. In the second step, the child's pregnant rats of experimental group
were distributed to three subgroups as follow: group I (without exposure to
noise stress), group II (exposure to noise for 8 weeks) and group III (exposure
to noise for 14 weeks) for morphometric analysis of their child's testicles
by sacrificing of them at weeks 14. In general, the testes of non-exposed group
were grown larger than ones in the noise exposed groups. Moreover, the testes
of the experimental group 1 were larger than the other experimental groups.
Indeed, the rate of atrophic seminiferous tubules and jumbled appearance of
the interstitial space were more observed in the noise stress exposed group
than non-exposed ones. In addition, seminiferous tubules analysis revealed that
the characteristics of interstitial space cells and epithelial germinative cells
of the seminiferous tubules in the control group were better than the noise
exposed groups. It seems that the noise stress has negative influences on the
fertility of male based on enhancing of the apoptotic process induced by pathogenesis
stress and suppressing the kinetics spermatogenesis.]]>Armario, A. and J.M. Castellanos,198412208210Chen, Z., R. Hauser, A.M. Trbovich, J.L. Shifren, D.J. Dorer, L. Godfrey-Bailey and N.P.
