Myths vs facts: Eisen-Ferritin Selbsttest and Fruchtbarkeit

Myths vs. facts: An iron-ferritin self-test can indicate iron status, but interpreting it for fertility is complex. Fact: Iron deficiency (low ferritin) can impair ovulation and implantation, while iron overload (e.g., hemochromatosis) also harms fertility. However, a standalone ferritin test only measures storage, not functional iron availability or inflammation (which elevates ferritin). Many commercial tests overstate their value – a normal ferritin does not rule out functional iron deficiency, and a low value alone does not explain fertility issues. Evidence for a direct causal link between ferritin and fertility is moderate, based on observational studies. For a thorough assessment, clinical lab work (including CRP, transferrin saturation) and individual history are needed. Myths: 'Higher ferritin means better fertility' – false, as excess is harmful. 'A self-test replaces a doctor visit' – no, it can only be a screening. Bottom line: The test can be a starting point but not a fertility diagnosis. Safety note: Always consult a physician when trying to conceive.
