The interpretation of the results was based on the value of the correlation coefficient: ±0.111–±0.333: low correlation; ±0.334–±0.666: moderate correlation; ±0.667–±0.999: high correlation. *P < 0.05; **P < 0.01; ***P < 0.001. MOT: spermatozoa motility [%]; PROG: spermatozoa progressive motility [%]; SOD: superoxide dismutase [U/mg protein]; CAT: catalase [U/mg protein]; GSH: glutathione [mg/mg protein]; ALB: albumin [mg/mg protein]; MDA: malondialdehyde [µM]; Na: sodium [mg/dL]; K: potassium [mg/dL]; Fe: iron [mg/dL]; Cu: copper [mg/dL]; Mg: magnesium [mg/dL]; Zn: zinc [mg/dL].
