Can FADS1 help with Fruchtbarkeit?

Whether FADS1 can help with fertility is not well established. FADS1 encodes a delta-5 desaturase involved in omega-3 and omega-6 fatty acid metabolism. Variants like rs174546 or rs174576 have been linked to altered polyunsaturated fatty acid levels in GWAS, which may influence prostaglandin synthesis and hormone regulation—processes relevant to fertility. However, direct evidence for a causal role in human fertility is limited. Most findings are mechanistic or from observational studies, not clinical trials. Fertility is multifactorial (age, hormones, lifestyle), and a single FADS1 variant likely has a small effect. Omega-3 supplementation for fertility is not strongly supported by evidence; any dietary changes should be discussed with a healthcare provider. Overall, the evidence is mechanistic/mixed and not sufficient to recommend FADS1-based interventions for fertility.
