Myths vs facts: Longevity DNA Test and fertility

The combination of longevity DNA tests and fertility is surrounded by myths. Fact: genetic tests like MTHFR C677T or APOE e4 are not validated for assessing fertility. The myth that MTHFR variants require methylfolate is debunked by guidelines – standard folic acid works for all genotypes. APOE e4 relates to Alzheimer's risk, not fertility. Microbiome tests show correlations, not causation for fertility issues. Evidence for such tests in this context is weak and often marketing-driven. For real fertility concerns, seek medical diagnostics (hormone panels, semen analysis, etc.) rather than DNA tests. Beware of exaggerated claims: longevity tests do not provide direct insights into fertility.
