The imbalance between total antioxidant capacity and ROS production in seminal fluid indicates oxidative stress and is strongly correlated with male IF.96 Unsurprisingly, both fertile and infertile smokers show a higher seminal ROS level.56 Sperm was considered to be particularly susceptible to oxidative damages due to the abundance of polyunsaturated fatty acids in the plasma membrane.97 As an exogenous antioxidant in semen, ascorbic acid played a most important role in controlling the oxidative stress.98 Serum ascorbic acid was found decreased significantly in heavy smoking group99 and their sperm quality improved after ascorbic acid supplement
