Testosterone is a male hormone produced by the testicles. Low Testosterone levels result from the insufficient production of Testosterone by the testicles.

Testosterone is the hormone responsible for sexual desire. It contributes to erectile function as erections occur when there is sexual stimulation. 

But the relationship between Testosterone and ED is complex. Some men with low Testosterone still experience healthy erections.

Does low Testosterone cause ED

The symptoms of low Testosterone may be physical, mental, or sexual. The sexual symptoms of low Testosterone include: 

  • Low sexual desire
  • Fewer sexually stimulated erections
  • Fewer spontaneous erections

Erectile Dysfunction may be a symptom of low Testosterone (low T). Research suggests that 1 in 3 men with ED may also have low T levels.

Not all people with low T have trouble with erections. Besides, people with high Testosterone levels may also develop ED.

Thus, low Testosterone is not a direct cause of ED. But it can contribute to ED in the following ways:

Low sexual desire: Men get erections when they experience sexual arousal. Low T might decrease desire and make it more difficult to become aroused to achieve an erection.

Stress: Low Testosterone frequently causes Anxiety and stress. As stress is a cause of ED, low T can hinder your ability to achieve an erection during sex.

Fatigue: Low levels of Testosterone may cause feelings of tiredness and fatigue. This could lower your desire to engage in sexual activity.

Weight gain: Fatigue and lack of physical activity due to low levels of Testosterone can increase body weight. It could put you at a greater risk for ED.

High Testosterone and Erectile Dysfunction

High Testosterone levels are not generally a cause of Erectile Dysfunction.

If you experience ED despite having a high Testosterone level, there may be another cause. In that case, you should consult a doctor for medical advice. 

But people who take Testosterone unlawfully may experience ED with other symptoms.

Excess Testosterone converts into Estrogen in your body. The rise of Estrogen may lead to Erectile Dysfunction.

Taking Testosterone without a doctor’s guidance may be extremely dangerous. Abnormally high levels of Testosterone may lead to low sperm counts and shrinking of testicles.

ED with normal Testosterone levels

Some people with normal Testosterone levels may also experience ED. In this case, ED may have developed due to a different cause. 

Your doctor may not prescribe Testosterone unless you experience other symptoms or signs of low T, like reduced sexual desire. 

Boosting Testosterone levels does not always improve your erections.

Will Testosterone help with ED

If you have low Testosterone and experience, you may try testosterone replacement therapy. You may benefit from combining Testosterone therapy with oral PDE5 inhibitor ED pills.

But Testosterone therapy may only help people with mild to moderate ED. It may not work for people with severe ED. 

If you have a severe case of Erectile Dysfunction, you should consult a doctor.
