Testosterone is a hormone made by the testicles. It is important for a man's sex drive and physical appearance.

Certain health conditions, medicines, or injury can lead to low testosterone (low-T). Testosterone level also naturally drops with age. Low testosterone can affect sex drive, mood, and changes in muscle and fat.

Treatment with testosterone therapy may help reduce symptoms.

Symptoms - Some men with low testosterone do not have any symptoms. Others may have:

• Low sex drive
• Problems having an erection
• Low sperm count
• Sleep problems such as insomnia
• Decrease in muscle size and strength
• Bone loss
• Increase in body fat
• Depression
• Trouble concentrating

Some symptoms may be a normal part of aging. For example, it is normal to feel less interested in sex as you get older. But, it is not usually normal to have no interest in sex.

Symptoms may also be caused by other conditions, such as high blood pressure or diabetes. If any of these symptoms are bothering you, talk with your health care provider.
