How are Fertility Check | Fruchtbarkeits-Test and Fruchtbarkeit related?

The Fertility Check (Fruchtbarkeits-Test) by MyBody-X is a home test that aims to provide insights into fertility-related factors via DNA and/or biomarker analysis. The term 'Fruchtbarkeit' simply means fertility in German. The test typically examines variants in genes linked to hormone regulation, oxidative stress, or detoxification – e.g., GPX1 (rs1050450), which affects glutathione peroxidase activity. However, the evidence for direct clinical utility is weak: most effect sizes are small, and fertility is predominantly influenced by non-genetic factors (age, lifestyle, environment). The test cannot diagnose infertility or replace medical evaluation. The relationship between the test and fertility is thus more informational and marketing-oriented than evidence-based. Caveat: always consult a healthcare professional before making decisions based on such results.
