Low Testosterone
or Low T

Testosterone is the primary male hormone and is made mostly by the testicles. It plays several important roles in life including increasing muscle mass and strength, enhancing sex drive, maintaining sperm production, improving bone density and producing new red blood cells.

It is normal for testosterone levels to decrease with age, but low testosterone (Low T) can cause bothersome symptoms that can be treated.

Symptoms of Low T

Low testosterone is diagnosed by a combination of bloodwork that shows a low testosterone level along with at least one of the following symptoms:

  • Low or decreased sex drive (libido)
  • Decreased energy
  • Decreased physical strength
  • Decreased lean muscle mass
  • Male infertility
  • Depression or mood disturbance
  • Poor memory
  • Difficulty concentrating
  • Hot flashes
  • Erectile dysfunction (ED)

Erectile Dysfunction (ED)

There is a link between Low T and Erectile Dysfunction.

Low T affects 2 to 4 million men in the U.S., or 60% of men over age 65. And the incidence increases as we age. This may affect a man’s erectile function.


The most common cause of low testosterone is normal aging, but low testosterone can be caused by a number of conditions that will be evaluated at your office visit.


Low testosterone is diagnosed by a healthcare provider through a combination of history and physical examination along with laboratory testing including the testosterone level.

Treatment with Testosterone Replacement Therapy (TRT)

There are a number of different treatment options that may be appropriate for use depending on each individual man’s symptoms and testosterone levels. Treatment options may include:

  • Topical testosterone therapy
  • Oral testosterone therapy
  • Intranasal testosterone therapy
  • Testosterone implant in the form of pellets
  • Testosterone injections


Regular follow-up visits are necessary to evaluate a man’s response to testosterone therapy and to check routine testosterone related blood tests.
