How are Magnesium and Fruchtbarkeit related?

Magnesium is involved in fertility through its roles in hormone regulation, oocyte maturation, and embryonic development. Deficiency may increase oxidative stress, impair egg quality, and is associated with higher miscarriage risk. In men, magnesium supports sperm motility and integrity. However, the evidence is largely mechanistic and observational; randomized controlled trials on magnesium supplementation for fertility are scarce and do not show clear clinical benefit. DNA tests (e.g., MTHFR, VDR) mentioned in the context do not directly assess magnesium status. A blood test for magnesium (serum or erythrocyte) is more informative than genetic testing. Supplementation should only be considered after confirmed deficiency or under medical supervision, as excess can cause adverse effects. Overall, the link is biologically plausible but clinically under-supported.
