What is Low Testosterone?

Testosterone is the hormone that puts hair on a man’s chest, bone mass, muscles, physical strength and the force behind a man’s sex drive.  Testosterone keeps a man’s muscles and bones strong and maintains their sex drive.  Testosterone levels change throughout your life, and after age 30 most men start a gradual decline in testosterone and a decreased sex drive.   

Talking with your Saint John’s Physician Partners doctor about this sensitive topic is an important step to understand what this means and what can be done about it. Even if you don’t have any visible symptoms, it may be a good idea to be tested for low testosterone since it can often lead to drops in bone density, which could lead to more fragile bones and prone to breaks. Most cases of low testosterone are treatable. 

Some issues that can contribute to low testosterone include: 

  • Medicines 
  • Genetics 
  • Aging 
  • Obesity 
  • Injury to testicles 
  • Testicular cancer 
  • Hormonal disorders 
  • Infection 
  • Type 2 diabetes 
  • HIV/Aids 
  • Chronic liver or kidney disease
