Reactive oxygen species (ROS) are naturally produced during sperm metabolism; however, excessive ROS leads to lipid peroxidation, DNA damage, and reduced motility.
Sources of oxidative stress include smoking, pollution, infection, varicocele, and metabolic disease. Elevated oxidative markers correlate with decreased fertility potential.
Antioxidant therapy—such as vitamin C, vitamin E, coenzyme Q10, selenium, and zinc—may reduce oxidative burden. Clinical trials demonstrate variable efficacy, underscoring the need for individualized therapy.
Combining lifestyle modification with targeted erotic supplementation yields optimal outcomes.
