One of the most common causes of low T is aging. As men age their testosterone production declines. The decline usually begins after age 30. Some men experience a more rapid decline and may experience symptoms of low testosterone in their 40s.

Diet and Excercise

Diet and exercise can have a significant effect on testosterone levels. A diet that lacks essential nutrients, such as zinc and magnesium, can decrease testosterone levels. Also, a lack of exercise can lead to reduced testosterone production.

Chronic Medical Conditions

Chronic medical conditions, such as diabetes or obesity, can decrease testosterone production. Conditions that affect the pituitary gland or hypothalamus (parts of the brain that regulate hormone production) can also lead to low testosterone levels.


Medications, including chemotherapy and steroids, can reduce testosterone. Certain drugs for treating depression, high blood pressure, and diabetes can also lead to low testosterone levels.

Testosterone Therapy

Testosterone therapy is one option for treating low T. This form of treatment involves taking a hormone supplement to make up for the body’s decreased production. To determine if testosterone therapy is the best treatment option for you, consult your physician.


Low testosterone can lead to a range of physical and mental health issues, so it should not be ignored. While aging is the most common cause of low T, it is important to consider diet, chronic medical conditions, medications, and other factors as possible causes. If you suspect that your testosterone levels are low, consult your physician to determine if testosterone therapy is right for you.
