What to watch with FADS1 and Fruchtbarkeit?

FADS1 (fatty acid desaturase 1) is a key enzyme in polyunsaturated fatty acid metabolism, especially converting alpha-linolenic acid (ALA) into long-chain omega-3s like EPA and DHA. These fatty acids are critical for hormone production, cell membrane function, and inflammation regulation – all factors that can influence fertility. Some studies suggest that certain variants in FADS1 (e.g., rs174537) are associated with altered blood levels of omega-3 and omega-6 fatty acids, which may in turn affect egg quality, sperm function, and menstrual cycle regulation. However, the evidence is not yet strong enough for direct clinical recommendations. Most data come from GWAS and mechanistic studies, not from randomized controlled trials. Effect sizes are generally small. A genetic test alone cannot diagnose fertility issues or guarantee a personalized diet. Interpretation must consider other factors (age, hormone status, lifestyle).
