What role does Fertility Check | Fruchtbarkeits-Test play in Stress?

The MyBody-X Fertility Check (Fruchtbarkeits-Test) is a direct-to-consumer DNA test that analyzes genetic variants claimed to be associated with fertility. Its role in stress is poorly supported by evidence. While chronic stress can impact fertility through hormonal pathways (e.g., cortisol, GnRH), the test does not measure stress markers or stress responses. Instead, it examines single SNPs (e.g., MTHFR rs1801133) with small effect sizes. The evidence is primarily marketing-based, not from robust clinical trials. The test cannot diagnose stress-related fertility issues or guide stress management. Users should view it as a curiosity rather than a clinical tool. For stress and fertility, validated biomarkers (e.g., cortisol, AMH) and professional evaluation are more appropriate.
