Salas-Huetos A, Bulló M, Salas-Salvadó J
Published in Human Reproduction Update
Methodology
Systematic review of 35 cross-sectional, case-control, prospective and retrospective observational studies on diet and semen quality or fecundability
Key Findings
Diets rich in omega-3 fatty acids, antioxidants (vitamin E, vitamin C, beta-carotene, selenium, zinc, cryptoxanthin, lycopene), vitamin D and folate, and low in saturated and trans fats, were associated with better semen quality and fecundability.
Conclusions
Overall dietary pattern, rather than any single supplement, tracks most consistently with male fertility parameters.
Limitations
Observational only; dietary self-report; residual confounding; no causal inference
Outcomes Measured
Generally, the results indicated that healthy diets rich in some nutrients such as omega-3 fatty acids, some antioxidants (vitamin E, vitamin C, beta-carotene, selenium, zinc, cryptoxanthin and lycopene), other vitamins (vitamin D and folate) and low in saturated fatty acids and trans-fatty acid
