Can Fertility Check help with blood sugar?

The Fertility Check from MyBody-X is designed primarily for reproductive health markers—hormones, cycle parameters, or genetic variants like MTHFR. It does not include direct blood glucose diagnostics. While mechanistic hypotheses exist linking MTHFR variants to insulin resistance via homocysteine and methylation, the evidence is weak and insufficient for clinical guidance. Blood sugar issues should be assessed with established methods (fasting glucose, HbA1c, OGTT). The Fertility Check may offer indirect clues but does not replace metabolic evaluation. Evidence for its utility in blood sugar management is therefore rated as 'unclear'.
