The Basics of the Male Fertility Diet
Imagine the baby we hope you’ll someday hold in your arms and call son or daughter. Now imagine feeding that baby a Big Mac, a Twix bar, or greasy French fries. Horrible thought, isn’t it? So why would you feed yourself that way? Why would you feed your sperm that way?
Feed junk into a system, and the system produces junk. Your body is no different. Bad fuel creates bad sperm. In our supplementation routine, we explained the power of antioxidants. These should increase your power to fight the damage caused by free radicals. Your diet is another way to do that. Decades of scientific research have found that men with a diet higher in antioxidants are more likely to produce sperm with the correct number of chromosomes. They also tend to have improved semen parameters such as sperm count and motility.
Small changes can make big differences. One study found that men with higher fruit and cereal intake had better sperm quality. This is likely due to the high levels in those foods of the antioxidant folate (Vitamin B⁹). Your partner may also be concerned with getting adequate folate in her diet, as it’s a standard recommendation for women to reduce the risk of birth defects. But it’s critical for men too. Folate plays a big role in protecting sperm DNA, and in one study men with higher folate intake were less likely to produce sperm with the chromosomal error that causes Down syndrome. Another study showed that folate, combined with other antioxidants, may even prevent or reverse the increase in sperm DNA damage associated with aging. Men with a diet high in antioxidants had sperm DNA quality similar to that of younger men.
But if you’re already taking your supplements, shouldn’t they take care of those pesky free radicals? Supplements are a great start, but a nutritious diet is important because the specific antioxidants found in supplements are just a small percentage of the vast array of antioxidants found naturally in food. For example, anthocyanins, which give berries their dark purple color, and beta carotene, found in sweet potatoes and carrots, are unlikely to be found in any multivitamin you’ve decided to take. There are many such examples, and research shows that your best approach is to eat a wide variety of fruits and vegetables, with a particular focus on the most brightly colored varieties, which are typically higher in antioxidants.
Obviously, there are also foods you shouldn’t be eating. These tend to contain chemicals or compounds that cause oxidative damage in the body. We’ll go into some of those foods below, but in general, a healthy diet results from following a few basic rules.
The Four Basic Rules of Healthy Eating
1. Eat real, unpackaged foods you cook yourself. Processed foods are notoriously harmful, and whatever harms the body harms your “sperm factory”. In addition, plastic-wrapped foods often carry Bisphenol A (BPA) and other chemicals that can mimic estrogen and disrupt hormones essential for sperm production. Finally, microwaving food in plastics or Tupperware can transfer microplastics or other harmful chemicals into the food, then into your body. These have been clearly shown to harm fertility.
2. Choose organic whenever possible. Research consistently demonstrates that exposure to pesticides can lead to a decline in sperm quality and a reduction in sperm counts.
3. Skip dessert. In case you hadn’t heard…sugar is really bad for you. Among other negative effects, it can lead to insulin resistance and hormonal imbalances, which negatively impact sperm production. See if you can skip dessert for the next 3 months. Too tough? Then allow yourself a weekly sweet “cheat”, and make sure it doesn’t come from a package.
4. Don’t drink anything that comes in a bottle or a can. See number 3. Even seemingly healthy canned or bottled drinks like juices or specialty waters contain added sugars or chemical sugar substitutes, not to mention other additives, preservatives, etc. Stick with water and unsweetened coffee or tea (note, however, that high caffeine intake has been linked to decreased sperm count and poor sperm DNA integrity, so keep it to 2 cups a day if you can). And if you need that morning glass of orange juice, squeeze it from an organic orange yourself.
Giving you months of fertility-friendly recipes is beyond the scope of this overview, but what we can do is give you a solid list of the ingredients you should be looking for, and a list of the ones you should be avoiding. You can find those in the two charts below. The first lists “Food for Fertility”. You’ll recognize many of the vitamins we covered in our post on supplements. Search for recipes containing lots of those. The second lists “Food for Infertility”. Get those ingredients out of the house.

FOODS FOR INFERTILITY
Food |
Examples |
Why It Hurts |
Processed Meats |
Sausages, bacon, deli meats |

Trans Fats |
Fried foods, margarine, packaged snacks |
Linked to reduced sperm count and poor sperm morphology |
Soy Products |
Soy milk, tofu, edamame |

Start today by choosing fertility foods and avoiding infertility foods. Although the lists above are not comprehensive, they should give you some general guidelines. In general, eat organic and unpackaged, cook for yourself, avoid sweets and anything that comes in a bottle or a can, and you’ll be doing yourself a favor.
It’s not that complicated. Make these changes to your diet for 3 months, and you’ll likely see positive effects on your fertility. Worst-case scenario, you’ll be healthier than you are today.
