Evidence check: Magnesium in the context of Fruchtbarkeit

Magnesium is an essential mineral involved in over 300 enzymatic reactions, including those relevant to reproduction. Some observational studies suggest a link between low magnesium status and reduced fertility – in men (e.g., decreased sperm motility) and women (e.g., ovulatory dysfunction, increased risk of pregnancy complications). However, the evidence is moderate: randomized controlled trials are scarce, and effect sizes are small. Magnesium deficiency can be assessed via blood or urine tests, but supplementation without proven deficiency is not generally recommended. MyBody-X tests can measure magnesium levels, but interpretation in the context of fertility should always be done with a physician. The provided context does not contain specific studies on magnesium and fertility; this answer is based on general medical knowledge. Caveat: supplements do not replace a medical fertility workup.
