Testosterone is a steroid hormone from the androgen group and is found in humans and other vertebrates. In humans and other mammals, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid.
Testosterone Biochemistry. By Dr Ananya Mandal, MD. Testosterone is the most important male hormone and is responsible for the changes boys go through to become men as they go through puberty. Testosterone is mostly produced in the testes and a small amount is produced by the adrenal glands. In women, the ovaries also produce a small amount. Testosterone is one of the steroid hormones and is therefore derived from cholesterol. Some of the steps in the synthesis of testosterone include breaking off or cleavage of the side chain of cholesterol by the mitochondrial cytochrome P450 enzyme, CYP11A.
