Healthy eating for conception for men

Learn more about why diet and nutrition is important when trying for a baby, and what supplements and vitamins to take that may help your fertility.

Pre-conception diet

Preparing your body for trying for a baby needn’t be too complicated or stressful. You are getting ready to carry a new life, and your partner needs to make sure his sperm is fit enough to reach its destination! Think about your eggs and sperm as being the earliest start of your future children; the healthier they are the better. It takes about three months for eggs and sperm to mature so filling your diet with foods that increase egg quality and male fertility before you start trying, will help you to conceive and carry a healthy baby.1

Fertility boosting foods and the mediterranean diet

A plant-based, anti-inflammatory, essentially flexitarian diet is good for all our health, but it is also especially good for improving fertility. Think Mediterranean; lots of colour, the brighter and stronger the better; fresh vegetables and fruit, green, orange, red and yellow, and black and purple berries 2,3. With nuts, seeds, lentils and beans, fish and white meat, wholegrains and olive oil, this diet is stuffed full all the vitamins and minerals that help fertility. Low sugar, complex carbohydrates and good quality animal and plant protein are essential for both male and female fertility, giving you energy, nutrients and the building blocks for eggs and sperm.  On the other hand, eating a lot of ultra-processed, fast foods, take-aways and fatty, sugary foods cause inflammation and can harm eggs and sperm.

Food

Caffeine and alcohol when trying to conceive

The research is a bit mixed about these two! And it’s very hard to give everything up in life when you start trying to conceive. However, certainly high intakes of caffeine may impact both male and female fertility3,4, so try and keep your teas and coffees down to the minimum, one or two cups a day.

Alcohol intake should be low for both, men and women, and especially for women during the second half (luteal phase) of the menstrual cycle - a glass on a Friday and Saturday, for example6,7. And no binge drinking!

Foods high in antioxidants for fertility

Antioxidants are compounds in certain foods that help to protect all our cells from damage, and that goes for eggs and sperm too8,9. Vitamins E and C, and the trace minerals zinc and selenium are essential nutrients for fertility.
 

  • Vitamin E is found in dark green leafy greens, nuts and seeds, avocados and olive oil.
  • Vitamin C is found in strawberries, citrus fruits, peppers, kiwi fruit and leafy greens.
  • Selenium is found in Brazil nuts (just two nuts a day will give you all you need!), chicken and turkey, lentils and garlic.
  • Zinc is found in all meats, shellfish, nuts and seeds and pulses

Fertility diet for men and women

You want to eat foods that can improve the way your reproductive hormones work, as well as your egg quality2. A diet rich in nutrients during that crucial period of egg maturation can make all the difference.
 

  • Wholegrains like bread, brown rice and pasta, oats and milled flax seeds contain important B vitamins for your reproductive hormones and compounds called lignans that help ovarian function10.
  • Orange vegetables contain beta-carotene for your ovaries
  • Almonds and all dark green vegetables are rich in hormone-balancing magnesium
  • Cruciferous vegetables like broccoli, brussels sprouts, cabbage and cauliflower help metabolise the hormone oestrogen.
  • Iron is also critical for fertility, especially if you have heavy periods (such as in endometriosis) and is found in lean free-range meats, fish, chicken, dark leafy greens, beetroot, dried prunes and apricots11.
  • Iodine is needed for the proper functioning of both the thyroid gland and the ovaries and is found in fish and dairy products11.

  • High zinc foods are vital for testosterone production, libido and sperm count12.
  • Walnuts, hazelnuts and almonds are especially good for sperm (with your two Brazil nuts)13 and vitamin C and E are essential for protecting sperm from damage as they swim along their way to meet the egg12.
  • Sunflower and pumpkin seeds contain plant sterols and zinc and tomatoes, especially concentrated tomato paste, and puree and sundried tomatoes are high in lycopene, important for the prostate gland and sperm health. Brazil nuts also contain the amino acid L.
  • Arginine, and meat is high in L. Carnitine, both important for sperm production and quality.14

Fertility supplements & vitamins

Supplements for female fertility

Folic acid when trying for a baby

As soon as you consider having a baby, it is recommended you take 400mcg of folic acid or folate which helps to prevent certain birth defects 15. It could be some time before you realise you are pregnant, and these early weeks can be critical. You may have a need for a higher dose of folic acid if you or your partner have certain medical conditions or a family history of neural tube defects, so a quick check in with your GP is a good idea if this applies.

Vitamin D for fertility

Always take a vitamin D supplement in winter, or even in summer if you don’t go out much in the sun, are usually covered or have darker skin. The NHS recommendation is 400iu/10mcg/day. 15

Is a vegan diet good for fertility?

If you eat a vegan diet you might need to supplement with iron, vitamin B1217, iodine and omega-3 from algae because these nutrients are only found in animal-derived products. Also, if you don’t eat oily fish, then supplementing with a good quality omega-3 may be beneficial16

If in doubt about supplements, always consult your healthcare practitioner for advice.

Supplements for male fertility

As for women, it is also recommended for men to take a vitamin D supplement, and a diet rich in vitamins, minerals and antioxidants is considered to be the best for male fertility9. But if you but if you find it hard to always eat healthily, or you have any dietary restrictions, are vegan or vegetarian, it’s a good idea to take an all-round male fertility pre-conception multivitamin containing zinc, vitamin C&E and selenium11. And again, if oily fish is not part of your diet, consider an omega three supplement.

PCOS endometriosis and fertility diet

These complex conditions that affect many women can also cause some problems with fertility. And diet plays a big role in helping to manage them and improving your chances of conceiving.

PCOS fertility diet

Manage your blood sugar; eat plenty of fibre and protein at meals and avoid foods high in sugar and refined carbs which shoot up your blood glucose and interfere with ovulation. Eat magnesium-rich leafy greens and oily fish with omega three fats and foods high in chromium like rye bread, meat and chicken, broccoli and seeds. Drink spearmint tea and consider taking the supplements Inositol and N-Acetyl Cysteine, which have been shown to improve blood sugar control and manage testosterone levels which can be elevated in PCOS18, 19, 20.

Foods to eat to increase fertility with endometriosis

An anti-inflammatory diet and reduction in red meat is essential for managing this often extremely painful condition. Eat plenty of milled flaxseeds, your Mediterranean diet, and spices like turmeric. Eat loads of magnesium rich greens and cut down wheat and refined grains.  Consider taking the supplements resveratrol and N-Acetyl Cysteine, which may reduce the inflammation and pain associated with endometriosis and add iron if your periods are heavy 21, 22
