Low Testosterone

Low Testosterone (Low T)

 
Hypogonadism, or testosterone deficiency (Low T), affects two to four million men in the U.S. and the prevalence increases with age.  It is estimated that while testosterone deficiency can affect up to 38 percent of the population, only five percent of affected men receive treatment.  

Men who have any of the following symptoms should be evaluated by a male sexuality expert.  The goal of the physicians in the Male Fertility and Sexuality Group at Chesapeake Urology Associate is to diagnose and treat men suffering from any of the below symptoms. 

Symptoms

Common symptoms of low testosterone may include:
  • Decreased energy
  • Decreased libido (sex drive)
  • Erectile dysfunction
  • Loss of muscle mass
  • Decreased exercise tolerance
  • Change in mental acuity or cognitive function
Low testosterone has also been linked to metabolic syndrome (obesity, high blood pressure, diabetes, and high cholesterol) as well as decreased bone density, or osteoporosis.  

Diagnosis

Low testosterone is often under diagnosed because other psychiatric and medical conditions, as well as medications, can cause these same symptoms.   The diagnosis of low testosterone should be considered if a man scores poorly on standardized questionnaires such as the Sexual Health Inventory for Men (SHIM).

How do you test for low testosterone?

A simple measure for hypogonadism is a blood test to check an early morning testosterone level.  A general recommendation is that a testosterone level less than 300 is considered low.   Low testosterone levels combined with clinical symptoms may warrant testosterone replacement therapy (TRT).
    

Treatment

Accepted methods of TRT in the United States include:
  • Skin patches
  • Topical gels
  • Injectable medications

Oral testosterone medications are currently not FDA approved due to potential liver toxicity.  Your testosterone level and other factors will determine which therapy is used.  Testosterone treatment can decrease sperm counts and even render men sterile (which is usually reversible), and so men desiring fertility should be given alternative medications to help boost their own natural testosterone levels.  Testosterone replacement therapy should never be used in men desiring fertility, and other treatments may be indicated such as an aromatase inhibitor or HCG.
    

How will I be monitored?

TRT requires close monitoring for changes in blood count, prostate-specific antigen (PSA) level, and liver enzymes.  This blood testing should take place two to four times per year, and a digital rectal examination in needed every 6 months for prostate cancer screening.
