Does low testosterone levels always need to be treated?

No!: I only treat it if the patient is symptomatic of the disease. Fatigue, low libido, bone or muscle loss, anemia, difficulty sleeping, moodiness, and ed can all be signs or symptoms of low testosterone. There are risks associated with the treatment. Every patient is different. Do your benefits outweigh the small risks of controlled replacement? That's between you and your doctor. @thepeedoc.

Not necessarily....: Generally, symptoms (such as fatigue, low muscle mass, low libido, etc.) are primary drivers of whether most people need to replace testosterone. The medical field is beginning to realize, though, that low testosterone levels are risk factors for a variety of chronic illnesses including dementia and earlier death. An informed conversation regarding the available literature is always a start.
