Additional Information

Within a man's body, there is a complex chain of signals called the Hypothalamic-pituitary-Gonadal Axis. The Testosterone produced in the testes is regulated by this chain. At the onset of puberty, there is a rapid increase in the production of Testosterone. But just as rapidly as it increases at puberty, Testosterone production begins to slow from the age of 30.
