The hypothalamus, a part of the brain, is responsible for many hormones. Understanding these brainy hormones will help you take control of your body and your health. The hypothalamus produces hormones that control the production of hormones in the pituitary gland.
The hypothalamus and the pituitary gland are important in controlling the amount of testosterone produced by the testes. In response to gonadotrophin-releasing hormone from the hypothalamus, the pituitary gland produces luteinising hormone which travels in the bloodstream to the gonads and stimulates the production and release of testosterone.
