Antioxidants and Fertility

Definition

Antioxidants are compounds that neutralize free radicals and reduce oxidative stress, a key factor in aging reproductive cells and causing infertility. They protect the DNA in sperm and eggs from damage.

How it works

Oxidative stress occurs when free radicals overwhelm the body's antioxidant defenses, damaging cell membranes and DNA. This process is particularly harmful to reproductive cells because sperm and eggs are metabolically active and vulnerable to oxidative damage. High oxidative stress is linked to poor sperm motility, low egg quality, and implantation failure. Antioxidants like vitamins C and E, selenium, and polyphenols from plants neutralize free radicals and protect mitochondrial function, which is essential for egg and sperm energy production. Research shows that antioxidant supplementation improves fertility outcomes in both men and women, particularly in cases of oxidative stress.

Role

Antioxidants neutralize free radicals and protect reproductive cell DNA and mitochondria from oxidative damage.

Examples

• Berries (blueberries, strawberries)
• Dark leafy greens
• Nuts and seeds
• Colorful vegetables (bell peppers, carrots)
• Green tea
• Dark chocolate
• Turmeric

Recommendations

Consume a variety of antioxidant-rich foods daily, focusing on colorful produce and whole foods. Consider supplementation with CoQ10 (100-600 mg daily) and selenium (55-200 micrograms) if recommended by your healthcare provider, especially if undergoing fertility treatment.

Key takeaway

Antioxidant-rich foods protect reproductive cells from aging and damage, making them essential for maintaining egg and sperm quality throughout your fertility journey.
