Myths vs facts: Fertility Check | Fruchtbarkeits-Test and fertility

Fertility tests (DNA- or hormone-based) are often marketed with exaggerated claims. Fact: A DNA test can detect certain genetic variants (e.g., in FMR1, CFTR, or MTHFR) linked to fertility issues, but effect sizes are small and predictive value is limited. Hormone tests (AMH, FSH) provide clues about ovarian reserve but are not a fertility oracle. Myth: 'A genetic test can tell me exactly whether I can have children.' – This is false. Fertility is multifactorial (age, lifestyle, environment, partner factors). Evidence for DTC fertility tests is mostly marketing-driven; many results lack clinical validation. Safety note: Always consult a doctor for fertility concerns – a home test does not replace a comprehensive fertility workup.
