Coenzyme Q₁₀, α-Tocopherol, and Oxidative Stress Could Be Important Metabolic Biomarkers of Male Infertility

Table 1

Comparison of sperm parameters, antioxidants, and TBARS in infertile men with different sperm motility groups.

	Sperm motility
Sperm density (10^6⋅mL^−1)
Sperm pathology (%)
	Seminal fluid
(g⋅mL^−1)
-Tocopherol (g⋅mL^−1)
TBARS (nmol⋅mL^−1)
	Blood plasma
(mol⋅L^−1)
-Tocopherol (mol⋅L^−1)
TBARS (mol⋅L^−1)

Statistical significance: versus ; , , and . Reference values of antioxidants in plasma: 0.4–1.0 mol⋅L⁻¹, -tocopherol 15–40 mol⋅L⁻¹, and TBARS < 4.5 mol⋅L⁻¹.
