    Abstract:
    We evaluated and compared serum oxidative and antioxidative parameters of patients with erectile dysfunction (ED) and control subjects. Twenty married male patients with ED for at least 12 months (Group 1) and 20 volunteer healthy, sexually active, married and age-matched men (Group 2) were included in the study. Group 1 and 2 were compared concerning serum mean total antioxidant capacity (TAC), total oxidant status (TOS), paraoxonase1 (PON1), arylesterase, total thiol and oxidative stress index (OSI). Mean patient age was 47.9 ± 8.1 and 44.4 ± 10.6, respectively, in Group 1 and 2. Serum TAC levels were 1.7 ± 0.5 and 2.3 ± 0.3, respectively, in Group 1 and 2 (P = 0.002). Serum TOS levels were 21.8 ± 20.5 and 11.7 ± 2.2, respectively, in Group 1 and 2 (P = 0.035). Serum PON1 levels were 69.8 ± 13.1 and 164.9 ± 56.5, respectively, in Group 1 and 2 (P < 0.001). Serum arylesterase levels were 336 ± 12 and 370.4 ± 47.9, respectively, in Group 1 and 2 (P = 0.003). Serum total thiol levels were 733.1 ± 253 and 885.5 ± 95.3, respectively, in Group 1 and 2 (P = 0.016). Serum OSI was 0.14 ± 0.17 and 0.05 ± 0.11, respectively, in Group 1 and 2 (P = 0.021). Mean blood platelet count was significantly higher in Group 1 (P = 0.001). A positive correlation between platelets and oxidative state and a negative correlation between platelets and antioxidative state were found. Oxidative stress was detected to be increased, whereas antioxidative parameters were detected to be decreased in patients with ED.
