Myths vs facts: Fertility Check | Fruchtbarkeits-Test and Blutzucker

The combination of fertility checks and blood glucose testing is surrounded by myths. Fact: Chronically elevated blood sugar (e.g., prediabetes or undiagnosed type 2 diabetes) can impair fertility in both women and men – through hormonal disruption, insulin resistance, and reduced egg/sperm quality. However, a standalone DNA test for 'fertility genes' (e.g., MTHFR, FSH receptor) does not provide a clinical diagnosis. The effects of individual variants are small, and fertility is dominated by age, lifestyle, hormonal status, and organic factors. Blood glucose tests (fasting glucose, HbA1c) are validated clinical markers. The myth that a DNA test can predict the 'ideal fertility diet' is overstated; evidence for nutrigenetic fertility recommendations is weak to moderate. A more sensible approach combines medical fertility workup (hormones, ultrasound, semen analysis) with long-term blood glucose monitoring. MyBody-X tests can serve as a screening tool but do not replace professional evaluation. Safety note: Always consult a specialist for unresolved infertility.
