Photomicrographs of testis sections of DZN-treated animals, (A) in 2 weeks of DZN exposure (15 and 30 mg/kg b.w.), treated animals showed disorganization and disintegration of cell, which caused secondary spermatocyte (arrows) moved into lumen (100×), (B) shrinkage (*) of seminiferous tubules and loss of cells (lc), (C) more immature cells appeared in the lumen of 30 mg/kg b.w. DZN-treated animals (arrows), and (D) abnormal formation of spermatozoa in the lumen. Slides were stained with haematoxylin-eosin dye. Scale of (A) and (B) – 200 µm, (C) and (D) – 100 µm.
