Fig. 1From: Ameliorative potential of the quercetin on lead-induced testicular damage: morphohistometric and biochemical analysisA control: normal histoarchitecture Sg: Spermatogonia, Sp: Spermatids, Sz: Spermatozoa, B Pb group: variable degrees of degenerative changes in the seminiferous tubules. Tubules contain highly vacuolated cytoplasm (V) with deeply stained pyknotic nuclei. Exfoliated germ cells (Ex) appear in the lumina of the seminiferous tubules. Some tubules have completely degenerated, C Quercetin + Pb group: restoration of the histoarchitecture (H&E scale bar, 50 μm)Back to article page
