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

The myth that a single fertility check or DNA test can reliably predict reproductive health is not supported by science. Many direct‑to‑consumer genetic test providers claim that SNPs in genes such as MTHFR, FSHR, or ESR2 mark fertility risk, yet large, randomized trials have not demonstrated that such classification is clinically useful. Clinical practice still relies on hormone measurements (FSH, LH, prolactin, AMH), ultrasound, sperm analysis, and possibly specialist screening tests that are founded on extensive studies and meta‑analyses. For skin health, while hormonal equilibrium (e.g., estrogen and androgen levels) can influence appearance of skin, hair, and nails, the predictive power of genetic findings remains limited. Individual therapeutic decisions should primarily involve consultation with a specialist; DNA tests complement, not replace, evidence‑based clinical diagnostics. Also consider data privacy – DNA testing is not a medical therapy and has no proven therapeutic effect.
