When fertility challenges arise, attention is often directed toward the woman. But growing research reveals that male factors are responsible for nearly 50% of infertility cases. One of the most underestimated contributors is Sperm DNA Fragmentation—a condition where the genetic material within the sperm is damaged, potentially impacting the chances of a healthy pregnancy.Even if a man has a normal sperm count, good motility, and healthy morphology, his fertility potential can still be compromised if the DNA within the sperm is damaged. Sperm DNA Fragmentation refers to breaks or abnormalities in the genetic code, which can lead to failed fertilization, poor embryo development, and increased risk of miscarriage.This damage can be caused by several factors, including oxidative stress, lifestyle habits (like smoking, poor diet, and alcohol), environmental toxins, infections, age, and even high testicular temperature. In many cases, men are unaware they have DNA fragmentation.Testing for sperm DNA fragmentation provides deeper insights that traditional semen analysis may miss. It helps fertility specialists tailor more precise treatment plans—ranging from lifestyle changes and antioxidant therapies to advanced reproductive techniques.The good news? Sperm DNA damage is often manageable and, in some cases, reversible. With proper diagnosis, targeted treatments, and healthier lifestyle choices, men can significantly improve their fertility potential.
