Sections from the rat testis administered with low-dose hair dye for 8 days show the following: a deformity (white arrows) and shrinkage (thin black arrows) of seminiferous tubules. Interstitial spaces were increased (stars) with compensatory hyperplasia of Lyedig cells (white star) (H-E, × 200). b Higher magnification show deformed tubule with homogenous material within the lumen masking the few number of mature sperms (white arrows), increase or hyperplasia of Lyedig cells (white star), and increase of tissue spaces due to atrophy of tubules (black star) (notice the blood vessel with thick wall) (dotted arrow) (H-E, × 200). c Some samples showed basal vacuoles between germ cells (black arrows). Tissue spaces are also widen (black stars) with hyperplasia of Leydig cells (H-E, × 200)
