Fatigue has many causes (sleep deprivation, stress, iron deficiency, thyroid dysfunction, infections) that a fertility test does not cover. Another myth: DNA tests can reveal 'fatigue genes.' In reality, genetic variants (e.g., MTHFR) are associated with homocysteine levels, but the effect on fatigue is small and not diagnostic.
