Testosterone Deficiency


Men who have a testosterone deficiency don’t produce normal amounts of the male sex hormone testosterone. Doctors call it hypogonadism. Some men are born with low testosterone. Injuries, infections and pituitary gland problems can cause testosterone deficiency, too.


Symptoms of testosterone deficiency in adult men include:

  • Decreased beard and body hair growth
  • Decreased sex drive
  • Depression
  • Development of breast tissue (also known as gynecomastia)
  • Erectile dysfunction
  • Fatigue and trouble concentrating
  • Infertility

Services & Treatment

To determine if you have a testosterone deficiency, your doctor will discuss your symptoms. He or she will also perform a physical exam. Every man’s testosterone levels decrease gradually with age, so your doctor will also order tests to make sure your symptoms aren’t related to a normal, age-related decline. 

After you’ve been diagnosed, your doctor will work with you on a treatment plan tailored to your needs. It might include testosterone replacement therapy or hormone replacement in the form of injections, patches, pellets or gels.
