Infertility is a growing problem worldwide.

It affects about one in every six couples, and researchers estimate about one in every three cases is due to fertility problems in the male partner alone.

While infertility is not always treatable, it can sometimes be improved with a healthy diet, supplements and other lifestyle strategies.

This article lists some of the main lifestyle factors, foods, nutrients and supplements that have been associated with improved fertility in men.

What Is Male Infertility?

Fertility refers to people’s ability to reproduce by natural means.

Male infertility is when a man has a poor chance of making his female partner pregnant. It usually depends on the quality of his sperm cells.

The following aspects of sexual function and semen quality may affect fertility:

  • Libido: Otherwise known as sex drive, libido describes a person’s desire to have sex. Foods or supplements that claim to increase libido are called aphrodisiacs.
  • Erectile dysfunction: Also known as impotence, erectile dysfunction is when a man is unable to develop or maintain an erection.
  • Sperm count: An important aspect of semen quality is the number or concentration of sperm cells in a given amount of semen.
  • Sperm motility: An essential function of healthy sperm cells is their ability to swim. Sperm motility is measured as the percentage of moving sperm cells in a sample of semen.
  • Testosterone levels: Low levels of testosterone, the male sex hormone, may be responsible for infertility in some men.

Infertility can have multiple causes and may depend on genetics, general health, fitness, diseases and dietary contaminants.

Additionally, a healthy lifestyle and diet are important. Some foods and nutrients are associated with greater fertility benefits than others.

Here are Science – Backed Ways to Boost Sperm Count and Increase Fertility in Men.

Exercise Regularly

Exercising not only improves your confidence and physical performance — it may also raise your testosterone levels.

Studies show that men who exercise regularly have higher testosterone levels and better semen quality than men who are inactive.

However, you should avoid too much exercise, as it may have the opposite effect and potentially reduce testosterone levels. Adequate zinc intake can minimize this risk.

If you rarely exercise but want to improve your fertility, becoming more physically active should be one of your top priorities.

Get Enough Vitamin D

Vitamin D is another nutrient that may boost your testosterone levels.

One observational study showed that vitamin D-deficient men were more likely to have low testosterone levels.

A controlled study in 65 men with low testosterone levels and vitamin D deficiency supported these findings. Taking 3,000 IU of vitamin D3 every day for one year increased their testosterone levels by around 25%.

Additionally, high vitamin D levels are linked to greater sperm motility, but the evidence is conflicting.

SUMMARY: Taking vitamin D supplements may boost testosterone levels in vitamin D-deficient men with low testosterone levels.

Get Enough Vitamin C

Oxidative stress is when levels of reactive oxygen species (ROS) reach harmful levels in the body.

It happens when the body’s own antioxidant defenses are overwhelmed because of disease, old age, an unhealthy lifestyle or environmental pollutants.

ROS are constantly being produced in the body, but their levels are kept in check in healthy people. High levels of ROS may promote tissue injury and inflammation, increasing the risk of chronic disease.

There is also some evidence that oxidative stress and excessively high levels of ROS may lead to infertility in men.

Adequate intake of antioxidants, such as vitamin C, may help counteract some of these harmful effects. There is also some evidence that vitamin C supplements may improve semen quality.

A study in infertile men showed that taking 1,000-mg vitamin C supplements twice a day for up to two months increased sperm motility by 92% and sperm count by more than 100%. It also reduced the proportion of deformed sperm cells by 55%.

Another observational study in Indian industrial workers suggested that taking 1,000 mg of vitamin C five times a week for three months may protect against DNA damage caused by ROS in sperm cells.

Vitamin C supplements also significantly improved sperm count and motility, while reducing the numbers of deformed sperm cells.

Taken together, these findings suggest that vitamin C may help improve fertility in infertile men suffering from oxidative stress.

However, controlled studies are needed before any definite claims can be made.

SUMMARY: Oxidative stress may lead to infertility in men. Some evidence indicates that taking antioxidant supplements, such as vitamin C, may improve fertility.

Relax and Minimize Stress

Stress may reduce your sexual satisfaction and impair your fertility.

Researchers believe the hormone cortisol may partly explain these adverse effects of stress.

Prolonged stress raises levels of cortisol, which has strong negative effects on testosterone. When cortisol goes up, testosterone levels tend to go down.

While severe, unexplained anxiety is typically treated with medication, milder forms of stress can be alleviated by numerous relaxation techniques. 

Stress management can be as simple as taking a walk in nature, meditating, exercising or spending time with friends.

SUMMARY: Stress can reduce sexual satisfaction and fertility. Stress management and relaxation should be high on your agenda.

Other Tips

Numerous strategies may help improve your fertility, although this depends on its cause.

Also, keep in mind that fertility and libido usually go hand in hand with your general health.

For this reason, anything that improves your overall health is likely to boost your fertility at the same time.

Here are 8 additional tips to boost fertility and sperm count/quality:

  • Lead a healthy lifestyle: Unhealthy lifestyle practices impair your overall health, including fertility.
  • Lose excess weight: Obesity is associated with infertility. If you are infertile and obese, weight loss should be one of your top goals.
  • Limit your alcohol intake: Avoid heavy alcohol consumption, as it may reduce testosterone levels and impair semen quality.
  • Get enough folate: A few studies indicate that a low intake of folate may impair semen quality.
  • Get adequate sleep: Getting adequate sleep is vital to maintaining your health. Restricted or excessive sleep has also been linked to poor semen quality
  • Snack on walnuts: Eating a lot of antioxidant-rich foods, such as walnuts, seems to benefit fertility 
  • Consider supplements: Antioxidant supplements also seem to work. Some evidence suggests that coenzyme Q10 improves semen quality.
  • Avoid eating too much soy: Soy is rich in isoflavones, which are associated with lower semen quality .
