What role does Omega-3 Index play in Fruchtbarkeit?

The Omega-3 Index (percentage of EPA+DHA in red blood cells) is linked to fertility primarily through its anti-inflammatory effects and role in cell membrane fluidity. Higher levels are associated with improved oocyte quality, sperm parameters, and endometrial receptivity in observational studies. However, the evidence is moderate: most data come from cohort or small intervention trials, not large RCTs. Omega-3s may also support hormonal balance (e.g., reducing prostaglandins, modulating cortisol) and improve menstrual regularity. Yet the Omega-3 Index is not a standalone fertility predictor; lifestyle, age, hormone status, and genetics (e.g., FADS gene variants) have stronger influences. An optimal index (>8%) is generally recommended, but individual responses vary. Home test kits provide a snapshot but lack clinical context. For fertility concerns, comprehensive evaluation by a reproductive specialist is essential.
