How are VKORC1 and Fruchtbarkeit related?

The relationship between VKORC1 and fertility is not scientifically established. VKORC1 encodes an enzyme involved in vitamin K metabolism and blood coagulation; its variants (e.g., rs9923231) are primarily studied for warfarin sensitivity. Some speculative hypotheses suggest vitamin K-dependent proteins might influence placental development or sperm function, but no robust human evidence links VKORC1 polymorphisms directly to fertility outcomes. Consumer DNA tests like MyBody-X do not include validated fertility markers for this gene. Evidence grade: unclear. For fertility concerns, clinical assessments (hormone panels, semen analysis) are far more informative than single-gene variants.
