How Testosterone Is Made


Testosterone therapy helps San Diego men increase their T levels when their bodies aren’t producing enough naturally. What’s the process for making testosterone in the first place, and how can a balance be restored?

The Life of Testosterone

Testosterone production is very complex. Approximately 95 percent of testosterone is produced in the testicles, with the remainder made in the adrenal glands. The process starts out with a message from the brain; the hypothalamus is responsible for detecting when the body needs more testosterone, and releases a chemical message via a special hormone that travels to the pituitary gland.

Once the pituitary gland hears from the brain, it creates two more hormones, FSH and LH, that travel to the testicles. These hormones stimulate sperm production, and also tell the Leydig cells to produce more testosterone. Leydig cells actually create testosterone by absorbing cholesterol from the bloodstream and converting it into testosterone. If cholesterol levels are low, the testicles themselves can produce enough to continue the process.

After testosterone is produced, it’s released into the bloodstream. Some of it binds to protein, while the rest circulates throughout the body. Once the hypothalamus detects that enough testosterone has been released, it tells the body to slow hormone production back down.
