Myths vs facts: DNA Stoffwechseltest and fertility

Myths vs. facts: DNA metabolism tests and fertility. A DNA metabolism test (e.g., MyBody-X DNA Nutrition Test) analyzes genetic variants related to energy metabolism, nutrient utilization, or detoxification. Some providers imply such tests can also inform about fertility. The fact is: fertility is multifactorial, depending on hormones, age, lifestyle, environment, and medical conditions. A DNA test may detect genes like MTHFR or VDR, which could indirectly relate to fertility – for example, via homocysteine or vitamin D metabolism. However, effect sizes are small, and clinical relevance for individual fertility is unclear. A DNA test cannot replace a gynecological or andrological workup, hormone testing, or analysis of sperm or ovarian reserve. The evidence for direct fertility insights from such tests is weak and often marketing-driven. Consumers should not base fertility decisions on DNA results alone. Safety note: Anyone with fertility concerns should consult a physician.
