Important clinical note

How foods can affect male fertility — quick primer

• Antioxidants (vitamins C, E, polyphenols) reduce oxidative stress that damages sperm DNA.
• Zinc & selenium are essential for sperm production, motility and testosterone metabolism.
• Omega-3 fatty acids (DHA/EPA) support sperm membrane fluidity and motility.
• Folate supports DNA synthesis and sperm quality.
• Vitamin D is linked to testosterone and sperm parameters.
• Adequate protein, healthy fats, whole grains and micronutrients support overall reproductive system function.

19. Tomatoes — source of lycopene, an antioxidant linked in some studies to improved sperm morphology. Key: lycopene, vitamin C.
20. Garlic — contains allicin and selenium; may support blood flow and antioxidant defenses. Key: selenium (trace), organosulfur compounds.
21. Onions — antioxidant flavonoids and supportive nutrients for general male health. Key: quercetin, antioxidants.
22. Ginger — traditionally used for male reproductive health; some studies show antioxidant and testosterone-supporting effects. Key: gingerols, antioxidants.
23. Turmeric (curcumin) — anti-inflammatory antioxidant; may reduce oxidative stress (use with medical advice if on medications). Key: curcumin.
24. Green tea — contains catechins (antioxidants); moderate consumption may be beneficial but avoid excessive intake due to caffeine. Key: catechins.
25. Dark chocolate (70%+ cacao) — source of antioxidants and magnesium; may support mood and blood flow (consume moderately). Key: magnesium, flavonoids.
26. Avocado — healthy monounsaturated fats, vitamin E and folate that support hormone production and sperm membrane integrity. Key: vitamin E, healthy fats.
27. Olive oil — rich in monounsaturated fats and polyphenols; supports cardiovascular and hormone health. Key: MUFAs, polyphenols.
28. Full-fat dairy (in moderation) — provides vitamin D, calcium and protein; vitamin D links to testosterone in some studies (balance with overall diet). Key: vitamin D, calcium, protein.
29. Oats — wholegrain source of B vitamins and fiber; supports metabolic health important for hormones. Key: B vitamins, fiber.
30. Quinoa — complete plant protein with magnesium and folate; useful for balanced diets. Key: protein, magnesium, folate.
31. Lentils & beans — plant protein, folate, iron and zinc (vary by type); support sperm production and general health. Key: folate, iron, plant protein.
32. Chicken (lean) — quality protein and B vitamins important for cell repair and hormone synthesis. Key: protein, B12.
33. Turkey — lean protein and selenium/iron depending on diet; supports overall reproductive health. Key: protein, selenium.
34. Shrimp — low-fat seafood providing selenium and B12; helps antioxidant balance. Key: selenium, B12.
35. Mussels & clams — good zinc and iron sources, low in mercury when sourced responsibly. Key: zinc, iron.
36. Yogurt & kefir — probiotic dairy that supports gut health; emerging links exist between gut and hormonal balance. Key: probiotics, protein, calcium.
37. Cheese (moderate) — source of protein and vitamin D in some varieties; include as part of balanced intake. Key: protein, calcium, vitamin D.
38. Black beans — folate, magnesium and plant protein supporting sperm formation. Key: folate, magnesium.
39. Beetroot — nitrates support blood flow; improved circulation benefits erectile function and testicular perfusion. Key: nitrates, antioxidants.
40. Carrots — beta-carotene and antioxidants that support overall health and hormone pathways. Key: beta-carotene, vitamin A.
41. Apples — flavonoids and fiber; part of a balanced antioxidant-rich diet. Key: fiber, flavonoids.
42. Bananas — vitamin B6, potassium and bromelain (in some varieties) which may support libido and energy. Key: B6, potassium.
43. Honey (raw) — antioxidants and small amounts of B vitamins; used traditionally for vitality (consume in moderation). Key: antioxidants, trace nutrients.
44. Shiitake & other mushrooms — vitamin D (especially if UV-exposed) and selenium; can support immune and hormonal health. Key: vitamin D (if exposed), selenium.
45. Oats & barley porridge with nuts — combined wholegrains and nuts deliver multinutrient support: zinc, magnesium, B vitamins and antioxidants. Key: B vitamins, magnesium.
46. Water (hydration) — often overlooked: adequate hydration supports semen volume and general physiological function. Key: fluids, electrolyte balance.

Note: many nutrients overlap across foods — aim for variety, whole foods, and balanced intake rather than single “superfoods.”

Practical tips for using these foods

• Eat a colourful, antioxidant-rich plate daily (fruits + vegetables + wholegrains + healthy fats).
• Include a reliable zinc source (pumpkin seeds, oysters, lean meat) and selenium (Brazil nuts, seafood) several times weekly.
• Aim for 2–3 servings of fatty fish per week (salmon, sardines) for omega-3s; plant-based omega-3s (walnuts, flax) are helpful too.
• Maintain healthy body weight — both underweight and obesity can impair fertility.
• Limit processed foods, trans fats, excessive alcohol, recreational drugs and high-temperature exposures (hot baths, saunas) that can reduce sperm quality.
• Consider discussing targeted supplements (zinc, selenium, folic acid, vitamin D, omega-3) with a clinician if diet alone is insufficient.

When to seek medical help

If you and your partner have been trying to conceive for 12 months (or 6 months if the female partner is over 35), consult a fertility specialist. Also seek evaluation if you have a history of mumps after puberty, undescended testes, prior chemotherapy/radiation, sexual dysfunction, or noticeable changes in testicular size or pain.
