Dietary and Lifestyle Interventions to Mitigate Oxidative Stress in Male and Female Fertility: Practical Insights for Infertility Management-A Narrative Review.
Plain-language summary
This narrative review set out to explore how oxidative stress (an imbalance between harmful reactive oxygen species and the body's defenses) affects fertility in men and women, and whether dietary and lifestyle changes can help. It pulled together findings from clinical, molecular, and translational studies on interventions like weight management, exercise, antioxidant supplements, and stress reduction. The review found that certain nutrients (zinc, selenium, vitamins C and E, polyphenols) and lifestyle shifts (cutting smoking and alcohol, managing stress, moderate exercise) can lower oxidative stress and improve reproductive health markers. It concluded that a combined approach tailored to individual biomarker profiles may offer a practical way to support fertility.
Key findings
- Oxidative stress harms sperm quality in men and egg health in women.
- Antioxidant supplements (like zinc, selenium, and vitamins C and E) may help neutralize harmful reactive oxygen species.
- Lifestyle changes like quitting smoking, exercising moderately, and managing stress can reduce oxidative stress.
- Biomarkers like DNA fragmentation and antioxidant levels can track the effectiveness of these interventions.
How to analyze the study yourself
- Study type
- Narrative reviews summarize existing research but do not systematically pool data or weigh study quality, so they give a broad overview rather than definitive answers.
- Population
- This review synthesized findings from various studies on men and women, but did not focus on a specific demographic.
- Funding
- Not reported
- Watch for
- Oxidative stress can hurt fertility by damaging sperm and eggs, but a diet rich in antioxidants (zinc, selenium, vitamins C and E, polyphenols) and lifestyle tweaks like moderate exercise and quitting smoking may help. If you're trying to conceive, it may be worth boosting these nutrients and cutting back on habits that spike oxidative stress.
