Myths vs facts: Fertility Check and Müdigkeit

Myths vs. facts: Fertility Check and Fatigue. A common myth is that a home fertility test (e.g., hormone measurement from saliva or blood) can directly explain why you feel tired. The fact is: fertility checks typically measure only a few markers like AMH, FSH, or LH – these are designed to assess reproductive potential, not to evaluate fatigue. 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. A blood test for homocysteine or B vitamins is more informative. Bottom line: fertility checks are useful for family planning, but not for diagnosing fatigue. Persistent tiredness warrants a doctor visit with comprehensive lab work. Evidence is based on clinical practice, not randomized trials.
