When it comes to fertility, both men and women should take measures to optimize their reproductive health. The foods we eat can have a profound impact on our fertility, particularly if we’re trying to conceive.

Certain foods can act as sperm killers, leading to decreased semen quality, reduced sperm count, and even infertility. If you’re looking to father children in the future, you might want to keep the following sperm killer foods out of your diet:.

Processed Meats

Processed meats like sausages, bacon, and ham are linked with poor sperm quality. The nitrates and nitrites in these meats, which are often used as preservatives, can cause damage to DNA and reduce sperm count.

Researchers found that men who ate processed meats frequently had lower sperm motility and more abnormally shaped sperm than men who didn’t eat those foods.

Soy Products

Soy products contain high amounts of phytoestrogen, which is a plant-based estrogen that can interfere with the body’s natural hormone balance and lower sperm production.

In fact, studies conducted on animals have shown that high consumption of soy-based foods can drastically reduce sperm counts. Men who are trying to conceive may want to avoid soy products like tofu, soy milk, and soy protein supplements.

Caffeine

While caffeine is a popular stimulant found in coffee, tea, and energy drinks, consuming too much of it can put a dent in male fertility.

A high caffeine intake can reduce sperm motility and increase the number of abnormal sperm, making conception less likely. One study showed that men who drank more than 265 mg of caffeine per day had a 39% reduction in sperm motility compared to men who drank less than 88 mg of caffeine per day.

Sugar-Sweetened Beverages

Soft drinks, energy drinks, and other sugar-sweetened beverages may be tasty, but they can harm sperm quality. These drinks are linked with poor semen volume, motility, and concentration.

Men who consume large amounts of sugar-sweetened beverages are more likely to have lower sperm counts and higher levels of inflammation, which can interfere with sperm function.

High-Mercury Fish

Fish is typically a healthy food choice, but certain types of fish contain high amounts of mercury, which can damage sperm and lead to infertility.

Mercury accumulates in the oceans, and large predatory fish like shark, swordfish, and king mackerel contain the highest concentrations. Men who are trying to conceive should limit their intake of high-mercury fish and choose safer options like salmon, sardines, and trout.

Processed Foods

Processed foods, like fast food and pre-packaged meals, are often high in unhealthy fats, sugar, salt, and artificial additives. These foods have been linked with numerous health problems, including poor sperm quality.

Men who eat a lot of processed foods have lower sperm concentrations, decreased motility, and abnormal sperm compared to men who eat a healthy, balanced diet.

Alcohol

Excessive alcohol consumption can negatively impact several aspects of male fertility, including sperm quality, count, and motility.

Studies show that drinking alcohol can reduce semen volume, increase the number of abnormal sperm, and cause erectile dysfunction. Men who are trying to conceive should aim for moderate alcohol consumption or abstain from drinking altogether.

Trans Fats

Trans fats are artificially made fats that are commonly found in processed foods, fried foods, and baked goods like pies and cakes.

These fats have been linked with several health problems, including cardiovascular disease and diabetes, but they can also disrupt male fertility. High trans fat intake is associated with poor semen quality, decreased sperm count, and reduced sperm motility. Men who are trying to conceive should avoid trans fats and choose healthier fats like olive oil, nuts, and seeds.

Low-Fiber Foods

Fiber is an essential nutrient that plays a crucial role in our digestive health, but it can also affect male fertility. One study found that men who ate a low-fiber diet had 23% less sperm than men who ate a high-fiber diet.

Eating a low-fiber diet can also lead to other health issues like constipation and weight gain. Men who want to optimize their fertility should aim for a high-fiber diet rich in fruits, vegetables, whole grains, and legumes.

Full-Fat Dairy

While dairy products are a good source of calcium and protein, consuming full-fat dairy products like whole milk and cheese can harm sperm quality.

Studies have shown that men who consume high amounts of full-fat dairy have lower sperm counts and reduced sperm motility compared to men who eat low-fat dairy. Men who are trying to conceive should opt for low-fat dairy products like skim milk and yogurt.

Conclusion

If you’re trying to conceive, it’s important to pay attention to the foods you eat. Certain foods can act as sperm killers, leading to decreased semen quality, reduced sperm count, and even infertility.

Avoiding processed meats, soy products, caffeine, sugar-sweetened beverages, high-mercury fish, processed foods, alcohol, trans fats, low-fiber foods, and full-fat dairy can go a long way in optimizing male fertility.
