Myths vs facts: Cardio Risk Check | Herz-Kreislauf Risiko-Test and fertility

The question of myths vs facts regarding Cardio Risk Checks and fertility touches on two separate domains. A cardio risk test (e.g., via DNA) can identify genetic variants associated with blood pressure, cholesterol, or inflammatory markers. However, the evidence for such tests is mostly mechanistic or GWAS-level; effect sizes are small and insufficient for clinical risk stratification. A direct link between these cardiovascular markers and fertility is not scientifically established. Fertility is determined by a complex interplay of hormones, age, lifestyle, and environmental factors. Some SNPs (e.g., in FTO) may be associated with both obesity and fertility issues, but the effect is indirect and small. Consumer DNA tests for cardiovascular risk have no clinical validity for predicting fertility problems. The evidence is best classified as 'unclear' or 'marketing'. Safety note: Do not base family planning decisions solely on such tests. Medical evaluation for fertility concerns is essential.
