Patient Education

Testosterone


Testosterone is used to treat symptoms of low testosterone in men who have hypogonadism (a condition in which the body does not produce enough natural testosterone). Testosterone is used only for men with low testosterone levels caused by certain medical conditions, including disorders of the testicles, pituitary gland, (a small gland in the brain), or hypothalamus (a part of the brain) that cause hypogonadism. Your doctor will order certain lab tests to check your testosterone levels to see if they are low before you begin to take testosterone. Testosterone should not be used treat the symptoms of low testosterone in men who have low testosterone due to aging ('age-related hypogonadism'). Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. Testosterone works by replacing testosterone that is normally produced by the body.
