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

The question of myths vs facts about fertility tests is important because many consumer tests overpromise. The provided knowledge base contains no specific information on fertility DNA tests. In general, clinically established markers such as AMH (anti-Müllerian hormone), FSH (follicle-stimulating hormone), and sperm analysis have moderate evidence for assessing ovarian reserve or male fertility. However, they are not predictors of pregnancy, only indicators. Consumer DNA tests linking single gene variants (e.g., in FSH receptor or ESR1) to fertility typically have only GWAS or mechanistic evidence, not clinical validation. The effect of single SNPs is very small; lifestyle, age, weight, and environmental factors dominate. A myth is that such a test can give a definitive answer about fertility. Fact: Only a comprehensive medical workup (hormone panel, ultrasound, semen analysis) provides a realistic picture. Safety note: Do not change family planning based solely on genetic tests. Evidence grade: mixed (clinical markers have practice evidence, direct-to-consumer genetic tests are mostly marketing).
