Can Homocystein help with Fruchtbarkeit?

Homocysteine is a biomarker, not a direct 'aid' for fertility. Elevated homocysteine levels are associated with fertility issues such as recurrent pregnancy loss and male infertility. Lowering homocysteine through supplementation with folic acid, vitamin B12, and B6 may be beneficial if a deficiency is confirmed. However, strong randomized controlled trials proving a causal benefit are lacking; evidence is mostly observational. A homocysteine test can serve as a risk marker but should not replace comprehensive fertility evaluation. Caution: self-treating with high-dose B vitamins without medical guidance is not advised.
