Comparison of 8-OHdG, NO, and TAC concentration in seminal plasma between fertile and infertile groups

Variable	Fertile (n = 40)	Infertile (n = 37)	Mean difference (95% CI)	p-value^a)
8-OHdG (ng/mL)	304.15 ± 126.29	389.66 ± 165.63	–85.51 (–152.08 to –18.94)	0.013
NO (μmol/L)	6.39 ± 4.59	7.94 ± 5.91	–1.54 (–3.94 to 0.84)	0.202
TAC (μM/L)	2,015.50 ± 670.95	1,697.11 ± 708.18	318.41 (5.31 to 631.52)	0.046

Values are presented as mean±standard deviation.

8-OHdG, 8-hydroxydesoxyguanosine; NO, nitric oxide; TAC, total antioxidant capacity; Fertile, healthy control group with a normal semen analysis; Infertile, patients with primary infertility and abnormal semen analysis; CI, confidence interval.

The p<0.05 was considered statistically significant. Independent t-test was used for comparisons between two groups.
