The Role of Oxidative Stress in Andrology

Oxidative stress occurs when the production of reactive oxygen species exceeds the antioxidant capacity of the reproductive system. While low levels of reactive oxygen species are necessary for normal sperm function, excessive levels are harmful.

Oxidative damage affects sperm membranes, DNA integrity, and mitochondrial function, leading to reduced motility and fertilization potential.

Sources of oxidative stress include smoking, pollution, infection, varicocele, and systemic disease. Antioxidant therapy has emerged as an adjunctive treatment, although patient selection erotic remains critical.

Managing oxidative stress is a key focus in contemporary andrology.
