What to watch with DNA Stoffwechseltest and Fruchtbarkeit?

Combining a DNA metabolism test with fertility is currently supported by weak evidence. The test analyzes genetic variants related to energy metabolism, methylation (e.g., MTHFR), or alcohol breakdown (ALDH2). Some variants may theoretically influence fertility – via homocysteine levels or oxidative stress – but evidence is mostly mechanistic or from association studies. The test does not replace standard fertility diagnostics (hormone panels, semen analysis, etc.). Effect sizes are generally small, and individual risks cannot be reliably derived. Beware of overinterpretation: a flagged variant does not necessarily indicate a fertility problem. It may be used as complementary information within a comprehensive reproductive health consultation. Evidence: marketing/unclear.
