Antioxidants

The best-studied fertility supplements are the antioxidants, notably Vitamins E and C, acetylcysteine and glutathione. In small studies, Vitamin E (tocopherol) has been shown to improve sperm function and IVF success rates. Ascorbic acid (vitamin C) has been reported to protect sperm DNA from the damage induced by exogenous oxidative stress in vitro. Other studies have also shown that higher levels of sperm DNA fragmentation, a marker of oxidative stress and possibly reduced fertility, are associated with lower levels of seminal ascorbic acid.
