About the Test

In men, testosterone is the hormone that regulates sex drive, builds bone mass, regulates body fat distribution, maintains muscle mass and strength, and is essential for the sperm production. Low levels of testosterone are associated with aging and common medical conditions including diabetes, high blood pressure, and obesity. Abnormal levels of testosterone in the blood may cause changes in health and physical appearance. If your results are not within normal range, it is important to consult with your physician to discuss next steps.

Testosterone is an androgen steroid hormone and the principal male sex hormone. Testosterone plays a key role in development of the male reproductive system and promotes secondary sexual characteristics such as facial and chest hair and upper body muscular build. It is primarily secreted from the testes. The Testosterone Test measures the level of testosterone in your blood to determine if your level is normal, high, or low.

A testosterone level that is lower or higher than normal can affect the body in many ways. In men, low testosterone levels are more common than high levels. Some men can have abnormal testosterone levels for years without knowing.

Symptoms of low testosterone in men can include:

Decrease in sex drive
Difficulty getting or maintaining an erection
Decrease in muscle mass
Bone weakness
Breast tissue development
Hair loss
Difficulty sleeping
Difficulty with memory and concentration
Decrease in testicle size
Decrease in semen production that can lead to fertility problems
