Myths vs facts: NutriCare | INFINITY DNA-Test and Fruchtbarkeit

The question of myths vs. facts regarding NutriCare/INFINITY DNA tests and fertility is valid. These direct-to-consumer tests analyze single genetic variants (e.g., MTHFR, FTO, VDR) that have been weakly associated in population studies with metabolic pathways theoretically linked to fertility. However, the evidence is mostly mechanistic or from GWAS – there are no randomized controlled trials proving a causal or clinically relevant benefit for fertility. Moreover, fertility is multifactorial: hormonal status, age, lifestyle, environment, and medical conditions play a far greater role than individual gene variants. MyBody-X itself states that its tests do not provide medical diagnoses and are not intended for disease screening. A DNA test may serve as a nudge toward a healthier lifestyle, but it cannot replace a proper fertility workup by a physician. Beware of overblown claims: most offered markers lack validated clinical relevance for fertility. Conclusion: evidence-based fertility counseling comes from gynecologists and endocrinologists, not from genetic tests bought online.
