Who should get a Total Testosterone?
Testosterone is the predominant male sex hormone which controls male sexual development and functions.
Testosterone levels vary with age. During puberty (teen years), testosterone levels are associated with pubertal changes including the development of body hair, changes in voice and increased muscle mass.
Testosterone levels will decrease with age as part of the normal physiology of aging. However, lower than normal testosterone or decreased testosterone can result in Low Testosterone (Low-T), or Testosterone Deficiency Syndrome (TD).
Low-T can result in a variety of symptoms including:
- Decreased sex drive and libido
- Fatigue
- Erectile Dysfunction
- Reduced muscle mass
- Fatigue
- Low Energy Levels
- Infertility
Testosterone levels also can be impacted by aging, obesity, metabolic syndrome, diabetes, and the use of certain medications including anti-depressants and narcotic pain medications. Testosterone levels can also decrease in health conditions such as HIV.
Testosterone levels should also be measured to monitor treatment in those taking testosterone supplementation.
