Folic acid is critical for DNA synthesis and cell division, making it essential during early pregnancy to prevent neural tube defects. For female fertility itself (conception probability), observational studies suggest that adequate folic acid intake may support ovulatory function and reduce the risk of anovulation. However, randomized controlled trials have not shown a clear effect on pregnancy rates. In men, folic acid is often combined with zinc to improve sperm quality, but the data are conflicting – some studies show modest improvements in sperm count, others show no benefit. The recommended dose for women planning pregnancy is 400–800 µg/day, starting at least four weeks before conception. Higher doses (above 1 mg) should only be used under medical supervision for specific risk factors (e.g., MTHFR variants), as they can mask vitamin B12 deficiency. The provided context does not include specific studies on folic acid and fertility, so this answer is based on general guidelines. Evidence: human-moderate.","area":"gesundheit","canonical_id":"gesundheit:canonical-8741677f27086e9fcfdac24d","id":"public-2e313c2f10455c7f0e4c01ca","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Folsäure in the context of fertility","score":21.79735584,"snippet":"The question about folic acid (vitamin B9) in the context of fertility is relevant, but the evidence requires careful interpretation.

However, the provided context contains no specific studies or genetic markers directly linking folic acid to fertility outcomes. In the scientific literature, folic acid supplementation before and during pregnancy is strongly recommended to prevent neural tube defects, but evidence for improved fertility (e.g., higher conception rates) is mixed. Some observational studies suggest a benefit, while randomized controlled trials often show no significant effect. Genetic variants in the MTHFR gene can affect folate metabolism, but they are not mentioned in the given context. Therefore, the evidence is rated as 'mixed'. A blood test for serum folate or homocysteine is more informative than a genetic test. Despite the mixed evidence for fertility itself, folic acid supplementation (400–800 µg/day) is widely recommended for women planning pregnancy, primarily based on its proven role in preventing birth defects.","area":"gesundheit","canonical_id":"gesundheit:canonical-a359fc6e89a02b489c5e0fe0","id":"public-b4e6d150a9281134f9d7f1e7","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: Folsäure in the context of Fruchtbarkeit","score":21.61481411,"snippet":"Folic acid (vitamin B9) is crucial for DNA synthesis and cell division – both key processes in fertility, especially for oocyte maturation and early embryonic development.
