Master Your T: The Definitive Guide to Raising Your Testosterone Naturally

by Christopher Walker

Here’s how the natural “feedback loop” of testosterone production operates: It all starts from the hypothalamus, which is an almond sized brain substrate that links your nervous system to the endocrine system. The first step of the process is simply when the hypothalamus releases a hormone called gonadotropin releasing hormone (GnRH). Keep in mind that this is the master hormone that starts everything. GnRH then stimulates the pituitary gland, which is a small pea sized endocrine gland protruding from the bottom of the hypothalamus. When the gland is stimulated by GnRH, it releases two hormones: luteinizing hormone (LH) and follicle stimulating hormone (FSH). These are the gonadotropins, and this is exactly why they first hormone is called gonadotropin releasing hormone. After the pituitary gland has released LH and FSH to the bloodstream, both of the hormones make their way from the brain, down to the ballsack. When they have reached their destination they enter the testicular leydig cells. Inside the leydig cells, the following events take place: FSH starts the process of spermatogenesis, whereas LH – through an extremely complex process – converts cholesterol into testosterone.
