Testosterone what it is!
What is testosterone?
Testosterone is a natural compound called a steroid hormone that falls under the androgen class of hormones. Although testosterone had been theorized for thousands of years it would be the 1930’s before the hormone was identified. The Organon group in the Netherlands were the first to isolate testosterone. They wrote about it in a 1935 paper called “On Crystalline Male Hormone from Testicles. They named the hormone testosterone, because the compound was isolated from the testes, was a sterol chemical, and possed a side group called a ketone.
Where is testosterone produced?
In male mammals, 95 percent of testosterone is primarily synthesized in the testes. In females most testosterone production occurs in the thecal cells of the ovaries and in far smaller quantities by the placenta. In both sexes small amounts of testosterone are also secreted by the adrenal glands as well as by the adrenal cortex. On average, an adult human male body produces about ten times more testosterone than an adult human female body, but females are, from a behavioral perspective more sensitive to the hormone.
How is testosterone synthesized?
Like most steroid hormones testosterone is synthesized by starting with the precursor molecule cholesterol. This occurs in males in the Leydig cells of the testes. Created for www.etestosterone.com
