Photomicrographs showing the reversal effects of quercetin therapy on endosulfanmediated histopathological changes in rats testes. A: Control (10 mL/kg of saline); B: AA (1.0 mg/kg); C: AA (2.0 mg/kg); D: FXT (10 mg/kg); E: FXT (10 mg/kg) + AA (1.0 mg/kg); E: FXT (10 mg/kg) + AA (2.0 mg/kg). For plate 1, slides A, B and C revealed normal testicular architecture with seminiferous tubules, normal matured sperm stage. Slide D revealed some pyknotic cell, sloughing/degenerated germ cell layer and less spermatozoa within their lumen and also shows vascular congestion. Different atrophic seminiferous tubules, thickened pyknotic propria enveloping the tubular cells, degenerated and necrotic germ cells of the seminiferous tubules. Slide E and F are associated with showing normal testicular architecture Blue arrow- few seminiferous tubules showing maturation arrest at secondary level; Slender arrow- represent vascular congestion and pinkish homogenous mass; Black-degenerated germ cell layer; White arrow- seminiferous tubule with normal sperm maturation; Spanned arrow- The interstitial spaces show normal Leydig cells. H & E (Hematoxylin-eosin) stain: Original magnification x400, Calibration bar = 0.01 mm (10 µm) for the entire plate.
