Evidence check: Fertility Check | Fruchtbarkeits-Test in the context of Müdigkeit

MyBody-X's Fertility Check typically measures hormones like AMH, FSH, LH, plus thyroid markers and vitamins. In the context of fatigue, these can hint at hormonal imbalances or nutrient deficiencies. However, limitations are significant: single finger-stick measurements (e.g., testosterone) fluctuate diurnally and are unreliable for clinical decisions. Chronic fatigue has many causes (sleep, stress, diet, mental health) that this test does not address. The genetic component (e.g., PER3 variant rs35333999) may slightly influence sleep duration, but effect sizes are small. The test is a screening tool, not a diagnostic workup. Persistent fatigue warrants a doctor's visit for comprehensive evaluation. Evidence is based on standard lab practice, but no studies validate this specific combo test for fatigue. Use cautiously and interpret results with a physician.
