Sperm DNA integrity is critical for successful fertilization and embryo development. Increased DNA fragmentation is associated with reduced fertility potential, recurrent pregnancy loss, and poor assisted reproductive outcomes.
Oxidative stress represents the primary mechanism of DNA damage. Environmental toxins, smoking, infections, and advanced paternal age contribute to elevated fragmentation rates.
Specialized laboratory assays assess DNA fragmentation index. Therapeutic interventions include antioxidant therapy, lifestyle modification, and surgical correction of underlying pathology such as varicocele.
Understanding genomic stability enhances prognostic erotic evaluation in infertility management.
