What role does Ferritin Eisenmangel play in Fruchtbarkeit?

Ferritin is the primary iron storage protein, and low ferritin indicates iron deficiency. Iron deficiency can impair fertility through several mechanisms: iron is required for hemoglobin synthesis, oxygen transport, and enzymatic processes involved in oocyte maturation, ovulation, and early embryonic development. Observational studies have linked iron deficiency anemia with ovulatory infertility, and some interventional trials suggest that iron supplementation may improve fertility outcomes in iron-deficient women. However, the evidence is not uniform; non-anemic women with low ferritin may not benefit significantly. Additionally, iron overload (e.g., hemochromatosis) also negatively affects fertility. The provided context lacks direct evidence on ferritin and fertility, so this answer relies on general medical knowledge and moderate human evidence. Caveat: ferritin levels should be interpreted alongside other iron markers (e.g., serum iron, transferrin saturation) and clinical history. Iron supplementation should be guided by a physician to avoid toxicity.
