Answering Popular Questions on Low Testosterone

What is Low Testosterone?

Testosterone is the male sex hormone that plays an important role in the sexual development and functioning of the body. It contributes to sperm production, develops muscle mass, and aids fat distribution.


So, why do some men have low testosterone? The reasons vary, with age being the most common, but you can also be born with lower levels of testosterone or acquire this through an injury.


The prevalence of low testosterone among men is not fully understood in science. Testosterone typically reaches its peak levels between a man's teenage years and into their twenties. This then drops by about 1% to 2% a year after age 40. As men age, this can lead to symptoms such as low desire, depression and anxiety. Decreased testosterone is a normal sign of aging -- however, if you do notice a significant decline, or your health is impacted, it’s always best to check in with your healthcare provider. 


What Happens When a Man’s Testosterone is Low? 


Symptoms of low testosterone may include:

  • Having a low sex drive

  • Difficulty maintaining an erection

  • A decrease in semen production 

  • Changes in mood, including irritability or an inability to focus  

  • Loss of hair, both body and facial 

  • Having increased body fat 

How Do You Fix Low Testosterone? 


The levels of testosterone in a man will gradually decrease over time, and this is simply a natural part of aging. However, there are ways to increase or maintain testosterone levels.


Many millions of men choose to use testosterone replacement therapy to overcome low testosterone. However, when other underlying health concerns such as diabetes or obesity are present, this type of hormone therapy won’t solve the issue alone.


Typically, testosterone replacement therapy is administered via injections, gels, or patches. These are prescribed depending on the severity of the situation, as they come with their own side-effects.
