Myths vs facts: DNA Stoffwechseltest and Fruchtbarkeit

Myths vs facts: DNA metabolism tests and fertility. Many direct-to-consumer companies claim that genetic variants (e.g., in MTHFR, COMT, VDR) affect metabolism and thereby fertility. Fact: Some variants have weak mechanistic links to homocysteine or vitamin D metabolism, which could theoretically influence egg quality or sperm function. However, clinical evidence is limited – no robust trials show that diet tailored to these variants significantly improves fertility outcomes. The MyBody-X Fertility Check measures hormones (AMH, FSH, progesterone), not DNA. A standalone DNA metabolism test does not replace medical fertility workup. Myth: 'My DNA test explains why I can't conceive.' Fact: Fertility is multifactorial – age, hormones, lifestyle, environment, and medical conditions dominate. DNA tests can provide at most weak clues, not diagnosis or guarantees. Be cautious of exaggerated marketing claims.
