What to watch with Pharmakogenetik Medicheck and Fruchtbarkeit?

When considering MyBody-X's Pharmakogenetik Medicheck and Fruchtbarkeit (fertility) tests, be cautious. The evidence is limited: pharmacogenetic markers like MTHFR C677T or A1298C are often overhyped – clinical guidelines do not support routine supplementation or dose adjustments based solely on these variants. For fertility tests, the context lacks robust studies; individual SNPs have tiny effects and are not predictive of actual fertility. These tests rely on GWAS associations or mechanistic reasoning, not RCTs. Important: never change medication without consulting a doctor, and fertility genetic tests cannot replace a full clinical workup (hormones, semen analysis, etc.). The evidence level is mostly 'gwas' or 'marketing'.
