Evidence check: Ferritin in the context of Fruchtbarkeit

Ferritin is the main iron storage protein and a key biomarker for iron status. In fertility contexts, both iron deficiency and iron overload can impair reproductive function – e.g., by disrupting ovulation, menstrual cycles, or early pregnancy. The provided knowledge contexts do not contain direct studies linking ferritin to fertility. There is a mention of HFE variants (iron metabolism) that may influence iron status, but no validated genetic test for ferritin levels exists. Ferritin is dynamically regulated by diet, inflammation, and other factors, making direct-to-consumer DNA predictions unreliable. Evidence for a genetic link between ferritin and fertility is unclear/mechanistic at best. Clinical assessment via blood ferritin measurement is essential. Caveat: iron supplementation without testing can be harmful in individuals with HFE mutations (hemochromatosis). For fertility planning, a comprehensive workup including ferritin, transferrin saturation, and inflammatory markers is recommended.
