Can Low Testosterone Cause Erectile Dysfunction?

Yes. Low testosterone can contribute to erectile dysfunction (ED), particularly by reducing sexual desire and affecting the biological processes involved in erections. However, low testosterone is only one possible cause of ED, and many men with ED have normal testosterone levels.

Testosterone plays an important role in male sexual health, including sexual desire and erectile function. When testosterone levels are abnormally low, a man may experience reduced libido and may also have difficulty achieving or maintaining an erection.

Possible signs associated with low testosterone include:

• Reduced sexual desire
• Fewer spontaneous or morning erections
• Erectile difficulties
• Fatigue or reduced energy
• Reduced muscle mass or strength
• Changes in mood or concentration

However, erectile dysfunction does not automatically mean that testosterone is low. Vascular conditions, diabetes, high blood pressure, medications, neurological problems, psychological factors, and other urological conditions can also cause ED.

The EAU recommends measuring early-morning total testosterone during the evaluation of men with ED, particularly when symptoms suggest testosterone deficiency. If a low result is found, further assessment may be required to determine whether testosterone deficiency is genuinely present and what may be causing it.

Treatment should be based on the confirmed cause. Testosterone treatment is not appropriate for every man with ED and should not be started solely because of erection difficulties.
