Comparative blood and seminal plasma oxidant/antioxidant status of Arab stallions with different ages and their relation to semen quality

To investigate the antioxidant/oxidant levels in blood serum and seminal plasma of Arab stallion with different ages and their relation to semen quality. Healthy Arabian stallions (n = 57), were divided into three groups. Young (5–10years), Moderate (11–16 years) and Old stallions (>16 years) were subjected to semen evaluation.
