What to watch with Omega-3 Index and Fruchtbarkeit?

The Omega-3 Index measures the percentage of EPA and DHA in red blood cell membranes and reflects long-term omega-3 status. Regarding fertility, moderate evidence suggests that a higher index is associated with better sperm quality (motility, morphology) and improved ovarian function in women. Omega-3s exert anti-inflammatory effects and may enhance blood flow to reproductive tissues. However, randomized controlled trials show mixed results. Genetic variants such as rs174546 in FADS1 affect the conversion of plant-based ALA to EPA/DHA; carriers of the T allele may benefit from direct intake of long-chain omega-3s. The Omega-3 Index is not a direct fertility test but a supportive biomarker. Optimal levels are >8%; values <4% indicate increased risk. Caution: very high fish oil doses (>4 g/day) may have blood-thinning effects. Individual response depends on genetics, diet, and inflammation status. The index should be interpreted alongside hormonal and lifestyle factors.
