Men Home > Symptoms of Low Testosterone
If a person has a deficiency of testosterone, the effects will primarily depend on the individual's age at the time the problem began. Low testosterone levels can occur at any age, including fetuses. If low levels occur in a male fetus, it can result in abnormal or absent male genitalia.
Young boys who have low levels of testosterone may have problems progressing through puberty. In some cases, puberty may not occur at all.
For adult men, symptoms of low testosterone will be more severe in younger men and become more subtle with age. Some of these signs may include:
- Fatigue and low energy
- Decreased muscle mass and increased fat mass
- Problems with impotence (also known as erectile dysfunction, or ED)
If you believe you may have symptoms of low testosterone, talk to your healthcare provider. A diagnosis should not be made based on symptoms alone. A simple blood test can determine whether you have this condition.
