Diet plays a meaningful role in sperm quality. Since a full cycle of sperm production takes about three months, dietary changes begun today can show measurable effects within 10–12 weeks. Here is a practical, evidence-based guide to foods and nutrients that support male fertility.
Antioxidant-Rich Fruits and Vegetables
Oxidative stress is a major contributor to poor sperm quality and DNA damage. Colourful fruits and vegetables rich in antioxidants help neutralise this stress. Include tomatoes (lycopene), berries, citrus fruits, pomegranate, spinach, broccoli, carrots, and bell peppers in daily meals.
Nuts and Seeds
Walnuts, almonds, Brazil nuts, pumpkin seeds, and sunflower seeds provide zinc, selenium, vitamin E, and omega-3 fatty acids. Clinical studies have shown that daily intake of 60–75g of mixed nuts can improve sperm count, motility, and vitality within a few months.
Fatty Fish
Salmon, sardines, mackerel, and tuna are excellent sources of omega-3 fatty acids, which support healthy sperm membranes and improve motility and morphology. Aim for two to three servings per week.
Eggs and Lean Protein
Eggs provide high-quality protein, vitamin D, and choline. Lean poultry, legumes, lentils, and dairy supply the amino acids and micronutrients required for healthy sperm production.
Whole Grains and Folate-Rich Foods
Whole grains, leafy greens, lentils, beans, and fortified cereals provide folate and B vitamins, which support normal sperm DNA and reduce the risk of chromosomal abnormalities.
Key Nutrients for Male Fertility

Beyond Food
Regular physical activity, adequate sleep, stress management, maintaining a healthy weight, and staying well hydrated all complement a fertility-friendly diet. A Mediterranean-style dietary pattern has the strongest evidence for improving male reproductive health.
