Coffee is one of the most popular drinks in the world, and for good reason. Coffee has been shown to improve energy levels, aid concentration, and is rich in antioxidants that are beneficial for health.

For men, a daily cup of coffee can do more than just wake up the brain. Some research suggests that men who drink two to three cups of coffee a day are less likely to develop erectile dysfunction.

Causes of erectile dysfunction

Erectile dysfunction (ED) is the inability to get or maintain an erection that is firm enough for sexual activity. ED is strongly linked to physical and psychological health.

Common causes of erectile dysfunction include:

  • Vascular disease: Reduced blood flow to the penis can cause erectile dysfunction.
  • Neurological disorders: Nerve damage from stroke, multiple sclerosis, or even diabetes can cause erectile dysfunction.
  • Mental Health: Stress, depression, and performance anxiety can all contribute to erectile dysfunction. A traumatic injury could also lead to the onset of erectile dysfunction.

Other risk factors for ED include:

  • Age (over 50)
  • Alcohol consumption
  • Drug use
  • Smoking
  • Obesity or lack of exercise
  • Sedentary lifestyle
  • Lack of sleep
  • Poor cardiovascular health (high cholesterol or high blood pressure)

ED prevalence

ED is very common. Although the risk of erectile dysfunction increases with age, young men can also suffer from it. Estimates of the prevalence of erectile dysfunction vary, but it is estimated that one in 10 men will suffer from the disease at some point in their life.

Can coffee cause erectile dysfunction?

Moderate caffeine consumption appears to have a positive effect on most people and does not seem to cause erectile dysfunction. In fact, one study found that drinking two to three cups of coffee per day can reduce the risk of developing erectile dysfunction.

However, too much caffeine can cause side effects such as anxiety, sleep disturbances, headaches, and heart palpitations, which can negatively affect your overall well-being and interfere with sexual function. .

Benefits of coffee for men

Besides providing a boost of energy, drinking a moderate amount of coffee each day can affect men’s reproductive health in other ways.

Erectile function

Men who drink two to three cups of coffee a day may find it easier to get and maintain an erection.

In fact, one study found that men who consumed between 85 and 170 milligrams of caffeine per day were 42% less likely to experience erectile dysfunction. Those who consumed between 171 and 303 milligrams of caffeine per day were 39% less likely to report erectile dysfunction than those who did not.

This may be due to the caffeine which relaxes the arteries and smooth muscles in the penis, allowing better blood circulation and improving erectile function.

However, a more recent study found no association between caffeine consumption and ED.


Research on caffeine consumption and its effects on male fertility is mixed.

One study found that consuming caffeine in sodas and energy drinks can reduce male fertility. Other studies have found no association between caffeine consumption and sperm quality.

Another review found that caffeine consumption can negatively affect male reproductive function, but concluded that more research is needed to determine the effect caffeine can have on male fertility.

Testosterone boost

Besides increasing energy levels, caffeine can also increase testosterone levels in men. Research shows that men who regularly consume caffeinated coffee have higher testosterone levels than those who do not.

One study found that consuming more than 4 milligrams of coffee before exercise increases testosterone levels in athletes. An older study has shown that chewing caffeine gum can increase testosterone levels by up to 14%.

Benefits of coffee for the heart

In addition to sexual health, coffee can also help improve heart health. Research suggests that coffee consumption is associated with a lower risk of heart failure.

Coffee is rich in antioxidants, which can protect blood vessels and reduce damage to the heart caused by cholesterol. Due to its antioxidant properties which aid circulation in the body, coffee can improve blood flow to the penis, helping men get and maintain erections.

Possible side effects

While coffee can offer some health benefits, it is important to drink it in moderation. Too much caffeine can cause a host of unwanted side effects, including:

  • Anxiety
  • Jitters
  • Headache
  • Insomnia
  • Increased heart rate
  • Stomach ache
  • Addiction

The Food and Drug Administration recommends consuming no more than 400 milligrams (about four to five cups of coffee) per day to avoid side effects.

Sensitivity to caffeine

If you are sensitive to caffeine, even a small amount of caffeine can make you feel bad. There are different degrees of sensitivity to caffeine: one person may be unaffected, while another may not be able to sleep for hours after consuming it. Caffeine sensitivity tends to increase with age, so you may need less coffee as you get older.

Facts about energy drinks

While the caffeine consumed in coffee is generally well tolerated by most people, energy drinks can have a number of negative effects, and there is no evidence that energy drinks can help fight erectile dysfunction.

Long-term consumption of energy drinks is associated with an increased risk of developing cardiovascular problems, sleep disturbances, dental problems, obesity, and calcium deficiency.

How much coffee before sex?

Coffee increases energy levels, improves physical stamina, and increases neurotransmitters associated with high mood, all of which can help improve your sex life.

However, you don’t need to drink an excessive amount of coffee before sex to reap the benefits. One or two cups 45 minutes before sexual activity can help improve erectile dysfunction, increase testosterone, and give you the energy you need for a positive sexual experience.

Natural ways to improve erectile dysfunction

There are a number of lifestyle changes you can make to improve erectile dysfunction, including:

  • Getting consistent good sleep
  • Exercise regularly
  • Eat a healthy diet rich in fruits, vegetables and protein
  • Limit alcohol consumption
  • Tips for dealing with any mental health issues, such as stress or performance anxiety, that can affect your sexual performance
  • Stop smoking

If you find that natural treatments aren’t helping improve your ED, talk to your health care provider. They will determine the cause of erectile dysfunction and recommend treatments.

A word from Verywell

Coffee can be a natural way to improve your sex life and erectile dysfunction issues. More research is needed to determine the effects of caffeine on men’s sexual health, but it appears that consuming a regular amount of coffee may reduce the risk of erectile dysfunction. Discuss your symptoms and treatment options for ED with your health care provider.

Frequently Asked Questions

  • Does Drinking Coffee Before Sex Improve Testosterone?

    Research suggests that coffee may temporarily increase testosterone levels, which may be beneficial before sex. Drinking coffee can also cause the cavernous smooth muscle present in the penis to relax and improve blood supply through the penile arteries to improve blood flow to the penis.

  • What is the connection between coffee and testosterone?

    Coffee can help increase testosterone levels in men. One study found that men who consumed caffeine five times a day had higher levels of testosterone than men who did not. The researchers concluded that caffeine can act as an aromatase inhibitor (blocking estrogen), which can stimulate testosterone production. Another study found that caffeine can improve exercise and training results due to its ability to moderately increase testosterone levels.

  • Does caffeine improve ED?

    Moderate levels of caffeine consumption can help improve erectile dysfunction. Research shows that men who consume between 85 and 170 milligrams of caffeine are 42% less likely to suffer from erectile dysfunction than those who do not consume caffeine.

  • Do symptoms of caffeine sensitivity increase with age?

    Yes, sensitivity to caffeine increases with age. Young people metabolize caffeine much faster than older adults. One study found that older people take 33% longer to metabolize caffeine than younger adults.
