Learn about low testosterone and how it affects you.


About Low Testosterone

As you age, it may feel like that you’re losing your drive for the things you love. You may be prone to changes in mood. In men, this could be attribute 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 and the male sex drive. It is mainly produced in the testicles of males; however, a small amount of testosterone is produced by the adrenal glands. While the production of testosterone peaks during puberty, the amount that the body produces begins to decline as you age. For more information on the causes and symptoms of low testosterone, please refer to their corresponding pages on our website.

How does ageing affect testosterone levels?

Testosterone levels in men peak between the ages of 20 – 30 years. As men age there is a gradual drop in testosterone levels. Some men may experience a greater drop in testosterone levels as they age, especially if they are overweight or have other long-term medical problems.
