Feeling down? If you have a lack of energy, experience big changes in your mood, or feel generally “foggy,” it’s possible that low testosterone, referred to as “low T,” is the culprit. Believe it or not, that “brain fog” is one of the most common symptoms for men who are suffering from low T. It’s also one of the first symptoms to start improving with regular and proper testosterone therapy.

It is not an uncommon problem. In fact, one in four men over 30 have low T levels. Research shows that testosterone levels are known to peak in men around the late 20s, and then decrease about 1.5% per yer after age 30. If you are experiencing “brain fog” and other symptoms, such as reduced energy, decreased strength, or irritability, it is worth it to get your testosterone levels checked and have the fog lifted.

Why would low T affect my mood?
You probably think testosterone as the hormone that affects sex drive and other related things, and yes, it is produced in your testicular region. However, the hormone balance in the rest of your body, of which testosterone is a large part, affects many other parts of your body, too. There are T receptors in your brain and muscles that accept “free testosterone,” which is unbound testosterone in your bloodstream. When T levels are low, this can starve those receptors and result in loss of muscle mass, lack of strength, fatigue, insulin resistance, decreased sex drive and changes of character.

How do I know if my “brain fog” or clinical depression is because of low testosterone?
Getting tested is the first step. Don’t just get tested for low testosterone — get tested for low levels of free testosterone, and for your general hormone balance levels. Low T therapy frees up other forms of testosterone in your body, allowing them to bind to the proper receptors and resume your body’s hormonal balance.

When the levels of free T are determined, then treatment with low T therapy can proceed, allowing you to eliminate your symptoms.
