Low sex drive, or libido, may stem from low testosterone, lack of sleep, stress, substance use, and more. If changes in your sex drive concern you, a doctor can offer more guidance.

Low libido describes a decreased interest in sexual activity.

It’s common to lose interest in sex from time to time, and libido levels vary throughout your life.

However, low libido for a long period of time can sometimes be an indicator of an underlying health condition.

Here are a few potential causes of low libido in males.

Testosterone is an important male hormone that’s mostly produced in the testicles. It plays a key role in:

Healthy testosterone levels for males range between 450 and 600 nanograms per deciliter (ng/dL), according to the American Urological Association (AUA).

However, adult males are considered to have low testosterone if levels fall below 300 ng/dL.

When your testosterone levels decrease, your desire for sex also decreases. Decreasing testosterone is a normal part of aging, but a drastic drop can lead to decreased libido.

Speak with a healthcare professional if you think this might be an issue for you. They could provide a proper diagnosis and recommend supplements or gels to increase your testosterone levels.

Taking certain medications could lower your testosterone levels, which in turn could lead to low libido.

According to the International Society for Sexual Medicine, these may include:

If you’re experiencing the effects of low testosterone and take any of these medications, speak with a doctor. They may advise you to switch medications.

Depression may lead to a reduced or complete lack of interest in activities you once found pleasurable, such as sex.

Low libido is also a side effect of some antidepressants, including:

Speak with a doctor if you’re taking antidepressants and experience low libido. They might address your side effects by adjusting your dose or having you switch to another medication.

Research suggests that chronic conditions in males most commonly affect two aspects of sexual function: libido and erectile function.

Chronic conditions that may affect sexual desire include:

If you’re living with a chronic condition and are sexually active, it’s important to be open about ways to be intimate and supportive. You may also consider speaking with a sex therapist.

Several sleeping disorders and conditions that could affect your sleep are associated with decreased libido, erectile dysfunction, and low testosterone levels. These may include:

If you experience decreased libido and sleep disturbances, speak with a healthcare professional. They may recommend a treatment plan that could include home remedies to sleep better and medication.

Testosterone levels, which are linked to libido, are at their highest during adolescence and gradually decrease as you age. This could lower your sex drive, and you may find it more difficult to:

A healthcare professional could recommend a treatment plan to help manage low libido and testosterone levels.

If you’re distracted by situations or periods of high pressure, sexual desire may decrease.

Research suggests that an increase in cortisol, also called the “stress hormone,” could disrupt hormone levels, lower libido, and increase your risk of erectile dysfunction.

Similarly, a 2019 study found that stress and personal burnout were associated with lower sex drive, erectile dysfunction, and decreased sexual satisfaction in males.

Some stress management techniques, such as breathing exercises, meditation, and talking with a therapist, may help improve libido.

Self-esteem is defined as a person’s general opinion about their own self.

Low self-esteem could take a toll on your sexual, emotional, and physical well-being. It may also cause anxiety about sexual performance, which could lead to issues with erectile dysfunction, reduced sexual desire, and avoiding sex altogether.

Over time, self-esteem issues can result in larger mental health problems, such as depression, anxiety, and drug or alcohol misuse — all of which have been linked to low libido.

Too little or too much exercise can also be responsible for low sex drive in males.

For instance, too little exercise (or none at all) can lead to a range of health problems that can affect sexual desire and arousal, such as:

On the other hand, over-exercising has also been shown to affect sexual health. In a 2017 study, higher levels of intense and lengthy endurance training on a regular basis were strongly associated with decreased libido scores in males.

The American Heart Association (AHA) recommends getting at least 150 minutes of moderate intensity exercise or 75 minutes of high intensity exercise weekly.

Heavy alcohol drinking, or more than 15 drinks in a week, is associated with a decrease in testosterone.

Over a long period of time, excessive amounts of alcohol can reduce your sex drive and lead to erectile dysfunction.

The Centers for Disease Control and Prevention recommends that males drink two or fewer alcoholic beverages daily. Any more than this can lead to long-term health issues.

However, it’s important to note that even drinking one or two drinks daily doesn’t provide benefits to health and longevity, as has been believed for years.

In addition to alcohol, the use of some substances and illegal drugs may lower your testosterone levels and affect sexual desire. These may include:

A decreased sex drive can be very unsettling.

Low libido can lead to a vicious cycle of physical and emotional side effects, such as:

If you experience low libido and it’s affecting your daily activities and mental well-being, speak with a healthcare professional. They could help develop a plan to increase your sex drive, which may include:
