Recently claims have been raised that noise stress may exert adverse effects on the reproductive functions. The present study was undertaken to investigate first; developmental histological characteristics of rat testis at 3 critical age periods namely; full term fetus, pre-pubertal and adult stages. Second, the impact of chronic noise stress exposure on testicular tissue at these age periods.
Albino rats were used and assigned into 3 groups; pregnant rats (to obtain fetuses at day 20 of gestation), prepubertal and adult male rats. Each group was subdivided into control and experimental subgroups. Experimental subgroups were exposed to noise stress (100dB), 6 hours daily for 30 days for Pre-pubertal and adult groups. While, pregnant rats were exposed to noise stress from day 8-20 of gestation then rats were sacrificed, testicles of fetuses were extracted. At the end of exper.. View More»
