Testosterone Replacement Therapy

What is Testosterone?

Testosterone is the sex hormone that helps boys become men. This hormone is key during puberty and the development of male physical features. Testosterone levels can affect men’s sex drive, erections, mood, muscle mass and bone density. Testosterone is also needed for men to produce sperm.

What is Hypogonadism or “Low-T”?

Some men have low levels of testosterone. This is called hypogonadism, or low-T. Men with low-T may also have problems such as:
  • reduced sex drive,
  • less frequent sexual activities,
  • fewer and weaker erections,
  • less energy,
  • depressed mood or irritability,
  • less muscle mass and strength,
  • more body fat,
  • anemia (low iron), and
  • loss of calcium from bone.

What is Testosterone Replacement Therapy (TRT)?

Testosterone replacement therapy (TRT) is approved by the FDA to treat men with hypogonadism (low-T). It most often comes in the form of gels, patches, injections (shots), and pellets placed under your skin.
