Myths vs facts: Fertility Check and Darmgesundheit

The pairing of fertility checks and gut health tests is often marketed as a holistic solution, but the evidence is weak. DNA-based fertility tests (e.g., MTHFR variants) are not recommended by guidelines or RCTs – folic acid works regardless of genotype. Home gut microbiome tests generally lack clinical utility; results vary widely between labs and reference databases. A standard blood panel including vitamins, thyroid markers, and hs-CRP can be useful for unexplained infertility, but it does not replace a specialist workup. Fact: A healthy lifestyle (diet, exercise, stress management) has a stronger proven impact on fertility and gut health than isolated genetic tests. Myth: A DNA test can predict your 'optimal' diet or fertility strategy. The evidence is mostly mechanistic or GWAS-derived, with no RCTs showing benefit. Be cautious of exaggerated claims – consult a reproductive endocrinologist or gastroenterologist for personalized advice.
