1. Exercise and sleep
Several studies have shown that weight loss and exercise in obese and overweight individuals can lead to improved or increased sperm counts. However, the science linking a healthy Body Mass Index (BMI) to a healthy sperm count is still weak.
A 2017 study found that performing a 16-week aerobic exercise program of at least 50 minutes of moderate exercise at 50 to 65 percent peak heart rate 3 times weekly, increased sperm volume and concentration in 45 sedentary, obese men.
2. Reduce stress

A healthful diet and exercise may help to reduce stress.
Any form of stress can cause the body to take defensive actions and conserve energy. In times of distress, it makes biological sense for the body to become less concerned with reproduction and more focused on surviving.
Reducing stress requires addressing the cause, though factors such as exercise and a healthful diet are thought to lessen the effects of stress.
For men who are experiencing severe stress, a doctor may prescribe anti-anxiety or anti-depressant medications.
3. Stop smoking
A 2016 study reviewing the results of over 20 different studies with a total of nearly 6,000 participants found smoking consistently reduced sperm count.
4. Avoid excessive alcohol use and drugs
The number of studies exploring the link between sperm health and drugs is limited given ethical considerations. However, some researchers have linked the worldwide use of drugs such as alcohol, marijuana, and cocaine to decreased sperm production.
5. Avoid several prescription medications
Some prescription medications can potentially decrease the healthy production of sperm. Once a person stops taking the drug, his sperm count should return to normal or increase.
Medications that temporarily reduce the production and development of sperm include:
anabolic steroids (up to 1 year recovery time)
6. Fenugreek supplement
Fenugreek has long been used as a natural remedy for poor sperm health, and advocates suggest it may improve sperm count. A 2017 study found that the patent-pending compound Furosap®, which is developed from fenugreek seeds, significantly improved overall semen quality and sperm count.
7. Get enough vitamin D and calcium
Researchers are not entirely sure why, but vitamin D and calcium serum appear to impact sperm health. Some studies have shown that low dietary vitamin D intake seems to correspond with lowered sperm count.
Ashwagandha, also known as Indian ginseng, has long been used in traditional medicines as a remedy for several forms of sexual dysfunction. A 2016 study found that 46 men with low sperm counts who took 675 milligrams (mg) of ashwagandha daily for 90 days saw a 167 percent increase in sperm count.
9. Increase intake of antioxidant-rich foods
Antioxidants are molecules that help remove and deactivate free radicals and other compounds that damage cells. Several vitamins and minerals have shown to act as antioxidants, and several studies have linked antioxidant consumption with increased sperm count.
Antioxidants that may contribute to a healthy sperm count include:
vitamin C (ascorbic acid)
10. Increase healthy fat intake
Polyunsaturated fats or so-called healthy fats, such as omega-3 and omega-6, are crucial to the healthy development of the sperm membrane.
Some studies have shown that individuals should consume these two essential omega compounds in equal quantities for ideal sperm development and antioxidant benefits.
11. Reduce unhealthy fat intake
A 2014 study that surveyed 209 healthy Spanish men between the ages of 18 to 23 years of age found that as they increased their consumption of trans fatty acids, their sperm count decreased proportionately.
Several studies have also shown that trans fatty acids may impair the ability of long-chain polyunsaturated fats to incorporate into sperm membranes, a critical step in sperm development.
12. Avoid or limit exposure to environmental or occupational toxins and contaminants
As the environment and atmosphere become increasingly polluted and congested, environmental factors, such as air quality and toxic chemical exposure, have frequently been linked to reduced sperm health and total count. Avoiding environmental toxins wherever possible also contributes to overall health.
It is important to point out that while some studies have shown a link between low sperm count and environmental contaminants, most of them do not support it.
13. Avoid too much soy or foods with non-human estrogen
Some foods, especially soy products, contain phytoestrogens (plant estrogen), compounds shown to reduce testosterone bonding and sperm production. Many canned and plastic products are also high in synthetic forms of estrogen.
14. Get enough folate and zinc
Consuming folate and zinc in combination has been shown in limited studies to increase overall sperm health, including sperm concentration or total count.
