What is testosterone?

Testosterone is the primary male sex hormone (androgen). It is responsible for the normal growth and development of male sex organs, and plays an integral role in: libido; mood; energy level; bone density; cognitive functions like memory and concentration; and secondary sex characteristics such as voice change, bodily hair growth, muscle mass, and fat distribution.

While men will naturally experience diminished testosterone levels as they age, even young men can struggle with low testosterone, or low T. Imbalanced testosterone levels can signal an underlying health concern. it’s always important to talk to a doctor if you begin showing signs of low T.
