Well, when you think of decreasing testosterone levels, you might think of middle-aged or older men. But you may be surprised to know that men under 30 too can experience low testosterone or “low T.” Generally, testosterone levels peak in men during adolescence and early adulthood, and levels start to decrease by about 1% every year from around age 30. However, men may experience declining testosterone at a younger age in a few cases.

What Is Low T?

Low T is a medical problem where the body doesn’t make adequate testosterone hormone levels. Both men and women produce testosterone, but it’s called the “male hormone,” as men make a lot more of it. This hormone is responsible for various male traits, including developing male sex organs, sperm, muscle mass, growth, voice intensification and hair growth. Low T can lead to several symptoms such as erectile dysfunction, infertility, low muscle mass, fat gain, and balding.

Low T is diagnosed when the levels fall below 300 ng/dL. As per the Food and Drug Administration, the normal value is between 300 to 100 ng/dL. Serum testosterone blood work is used to determine levels of circulating testosterone.

If you think you might have a low T, fix an appointment with your doctor. In some cases, unhealthy lifestyle behaviours can be one of the causes, which can be modified. In other cases, it is caused due to an underlying medical problem that needs treatment. Read this article to learn more about the signs of Low T and learn how to manage them.
