Does low testosterone make you tired?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Yes, low testosterone can cause significant fatigue, as this hormone plays a key role in regulating energy, mood, and metabolism. When testosterone levels drop, many people experience persistent tiredness, weakness, difficulty concentrating, and reduced motivation, even after a full night's sleep.

Fatigue can stem from many causes beyond low testosterone, including thyroid issues, anemia, sleep disorders, or stress. Because the symptoms overlap, it's important to identify the root cause before assuming hormones are to blame. A quick, free symptom check can help you understand what's driving your fatigue and guide your next steps toward the right care.

Explanation

Testosterone is a hormone that helps give you energy and strength. When you have low testosterone, a condition sometimes called hypogonadism, you might notice that you feel very tired or run down. This happens because there isn't enough of the hormone to support all the body's functions that need energy.

Doctors have found that men with low testosterone often feel more fatigue, and some research shows that treatments to increase testosterone can help reduce these tired feelings.

It's important to know, though, that feeling tired can be caused by many things, not just low testosterone. If you feel constantly tired, you can check your symptoms with a free AI symptom checker to better understand what might be causing your fatigue, then talk to a doctor who can check your hormone levels and provide a proper diagnosis. They can then help you decide if treatment for low testosterone or another treatment might work best.
