When its level drops, a range of symptoms appears that can affect quality of life. In this article we review the main causes of low testosterone, its symptoms, and the tests needed to diagnose it.

Testosterone is produced mainly in the testicles, and its production is influenced by signals from the brain.

Its Role in the Body

• Building muscle mass and bone strength.
• Regulating libido and reproductive ability.
• Influencing mood and energy levels.
• The normal range in adult men is usually between 300 and 1000 ng/dL, with values varying between labs.

Age and Lifestyle-Related Causes

Many cases of low testosterone are linked to controllable factors.

Common Factors

• Aging, as the hormone gradually declines after the ages of 30 and 40.
• Obesity and excess weight, which negatively affect hormone production.
• Lack of sleep and chronic stress.
