How are DNA Stoffwechselanalyse | inkl. 28-Tage-Plan & Rezeptbuch and fertility related?

The DNA Stoffwechselanalyse (including a 28-day plan and recipe book) is a direct-to-consumer test that analyzes genetic variants related to macronutrient metabolism, weight regulation, and energy balance. It does not directly assess fertility – it measures no hormones, ovulation markers, or fertility-related genes such as FSH receptor or AMH. However, an indirect link exists: overweight, insulin resistance, and metabolic syndrome (e.g., in PCOS) impair fertility. The 28-day plan and recipe book may help implement healthier eating and weight loss, which can improve fertility outcomes. The evidence for the test itself is weak: the effects of the tested SNPs are generally small, and the 'metabolism type' classification lacks scientific validation. The test is not a medical tool for fertility diagnostics. Women trying to conceive should rely on established methods (cycle tracking, hormone panels, lifestyle counseling) rather than this DNA test. The evidence level is 'marketing' – the test offers lifestyle inspiration but no validated fertility prediction.
