. A-Diameter of tunica albugina in control and different test and groups. There are no evident of differences in low dose group in comparison to control group, but in high dose group there is highly significant (P<0.001) increase in diameter of tunica albugina only after 45 days of pyridaben obtain. B- Thicknesses of epithelium of seminiferous tubules in control and different test groups. The significant (P<0.01) decrease in this parameter is evident in low dose group at 45 days, but in high dose group the decrease in this parameter were evident at 25 and 45 days. C- Thicknesses of testicular interstitial tissue not revealing differences in between test and control groups. D- Diameter of seminiferous tubules in test and control groups in low dose group a highly significant increase in this parameter is evident only at 10 days treatment ,but in high dose group this increase is evident at 25 and 45 days after exposure to pyridaben
