Testosterone and You

Testosterone is the most important male sex hormone (androgen). In men, more than 90% of testosterone production takes place in the testes. A considerably smaller amount is produced in the outer layer (cortex) of the adrenal glands.

Testosterone has different functions in different phases of life.

In the unborn child it causes male sexual differentiation while during puberty it is responsible for virilisation (masculinisation).

In the adult male testosterone controls all sexual functions (libido, potency, fertility). In addition, it preserves the typical male build and appearance. It is important for physical health and performance and also has a decisive influence on mood and sensation of wellbeing
