A – Sperm count, B – sperm motility, C – sperm viability, D – HOS tail-coiled sperm, E – abnormal sperm, F – (i) normal, (ii) rod head, (iii) pin head, (iv) bent middle piece, (v) bent neck, (vi) bent neck and (vii) tail, (viii) rod head and enlarged tail, (ix) HOS tail coiled sperm

Arrow shows live sperm and dotted arrow shows dead sperm. Values represent mean ± SEM of six different observations. *P < 0.05 compared to NC, ^#p < 0.05 compared to DC. NC – normal control, DC – diabetic control, NC + Q10 – normal receiving 10 mg/ kg/b.w. quercetin, NC + Q25 – normal receiving 25 mg/kg/b.w. quercetin, NC + Q50 – normal receiving 50 mg/kg/b.w. quercetin, DC + Q10 – diabetic receiving 10 mg/kg/b.w. quercetin, DC + Q25 – diabetic receiving 25 mg/kg/b.w. quercetin, DC + Q50 – diabetic receiving 50 mg/kg/b.w. quercetin, scale bar = 50 μm.
