In the context of fertility, iron deficiency can impair ovulation, egg quality, and overall reproductive health – this is supported by clinical observation but not by specific studies in the provided context. The test is a standard laboratory procedure (evidence: practice), but it alone is insufficient for a fertility diagnosis. Important caveat: ferritin can be falsely elevated in inflammation, complicating interpretation. MyBody-X offers such tests for adults, but for fertility concerns, a medical workup including hemoglobin, transferrin saturation, and inflammatory markers is essential.

In women, iron deficiency may impair ovulation and implantation because iron is critical for cell division and oxygen transport. In men, some studies suggest negative effects on sperm quality. The evidence is mostly observational; there are no large RCTs specifically linking ferritin levels to fertility outcomes as a standalone marker. A ferritin level below 30 µg/L indicates iron deficiency, but interpretation requires clinical context including hemoglobin, transferrin saturation, and inflammation markers. A consumer DNA test for ferritin is not useful because ferritin is regulated by diet, blood loss, and inflammation, not genetics alone.
