About Low Testosterone
As you age, it may feel like that you’re losing your drive for the things you love. You may also feel weaker, or even prone to changes in mood. In men, most would attribute this to decreased testosterone levels. But what does that really mean, and how does that affect men?
Testosterone is the primary sex hormone responsible for everything from the development of the male reproductive tissues, to the development of muscles, to the growth of body hair. It is mainly produced in the testicles of males.
This hormone also drives the male sex drive. Healthy men generally have testosterone levels between 300 nanograms per deciliter (ng/dL) and 1,000 ng/dL. While the production of testosterone peaks during puberty, the amount that the body produces begin to decline by age 40.

What are “Normal Levels” of Testosterone?
In healthy men, testosterone levels between 350 ng/dL and 1,000 ng/dL are referred to as normal. Normal physiology allows the brain and the testes to work together to keep testosterone in this range. The brain produces “signal” hormones that are responsible for stimulating testosterone production. These “signals” are periodically released, which in turn stimulates testosterone production. When levels of testosterone are in an acceptable range, the production of the “signal” hormones is slowed, which in turn allows the testosterone levels to decrease.

The loss of testosterone, as a man ages, is a regular finding in medicine. Many men experience an average loss of 1% of their testosterone per year, simply from factors associated with the production. This percentage does not take into account other factors that may affect the production of this hormone.
