Can Erectile Dysfunction Be Caused by Low Testosterone?

Yes. Low testosterone can contribute to erectile dysfunction (ED), particularly by reducing sexual desire and affecting erectile function. However, low testosterone is not the only possible cause of ED, and many men with ED have normal testosterone levels.

Testosterone plays an important role in male sexual health. When testosterone levels are abnormally low, some men may experience reduced sexual desire, fewer spontaneous erections, and difficulty achieving or maintaining erections.

Low testosterone may be associated with:

• Reduced sexual desire
• Fewer morning or spontaneous erections
• Difficulty achieving or maintaining an erection
• Fatigue or reduced energy
• Changes in mood
• Reduced muscle strength or mass

However, ED can also result from diabetes, cardiovascular disease, high blood pressure, obesity, medications, neurological conditions, psychological factors, smoking, and other urological problems.

The EAU recommends checking early-morning total testosterone during the assessment of men with ED. If the level is low, further evaluation may be needed to confirm testosterone deficiency and determine its cause. Testosterone treatment is not automatically appropriate for every man with ED.

At SCI International Hospital, Dr. Gautam Banga assesses hormonal, vascular, metabolic, psychological, medication-related, and urological factors when evaluating erectile dysfunction. When appropriate, testosterone testing can help determine whether hormonal deficiency is contributing to the problem and guide treatment.
