Evidence check: Omega-3 Index in the context of Fruchtbarkeit

The Omega-3 Index measures EPA and DHA in red blood cell membranes and is a validated marker for cardiovascular health. In the context of fertility, some evidence suggests omega-3 fatty acids may improve sperm quality (motility, morphology) and support female reproductive health (oocyte quality, menstrual regularity). However, direct evidence linking the Omega-3 Index to fertility outcomes is limited. Observational studies show associations, but randomized trials are mixed and often underpowered. The index is highly modifiable by diet and supplementation, and a low index (<4%) indicates higher inflammation, which could indirectly affect fertility. Yet, fertility is multifactorial; the Omega-3 Index alone is not a reliable predictor. Clinical assessment (hormones, age, lifestyle) remains paramount. Evidence: human-moderate. Caveat: No large-scale interventional trials specifically validate the Omega-3 Index as a fertility biomarker. No specific sources from the provided context.
