Common causes of DNA fragmentation can be traced back to various medical conditions/conditions such as: infections, smoking, heat, stress, prescription medications, drug use and pesticides among other causes listed. Sometimes reducing or removing the possible contributor can reduce elevated levels of DNA fragmentation.
What Causes a High DFI (DNA Fragmentation Index)?
LIFESTYLE: smoking, drug use, increased alcohol consumption, obesity, stress
NUTRITION: Although commonly overlooked, we have often seen drastic improvement in sperm DNA fragmentation after a detailed analysis and correction of daily nutrition.
HEAT EXPOSURE: e.g. from whirlpool baths, working with a laptop on the lap, fever, etc.
OCCUPATIONAL EXPOSURES: chemicals, pesticides, fertilizers, dyes, etc.
DIABETES: An independent risk factor for increased sperm DNA fragmentation
MEDICATION: Even the most unassuming medications have sometimes seen to cause sperm DNA fragmentation
ENVIRONMENTAL TOXINS /air pollution: Although it may appear general, a keen look into exposure should be ruled out.
VARICOCELE: Once diagnosed either by examination or ultrasound, SCSA test can help in the decision if surgery will help.
CANCER AND CANCER TREATMENTS (chemotherapy and radiotherapy) : causes direct damage to the DNA of cells.
CHRONIC DISEASES: often cause increased oxidative stress leading to increased DNA damage
ANDROLOGICAL DISEASES / Infections of the urogenital tract and leukocytospermia: Local infection / inflammation causes direct damage to the DNA in sperm through release of ROS (Reactive Oxygen Species).
AGE >40 YEARS: It has been extensively studied that the older the man, the higher the DNA fragmentation
