Testosterone can be a steroid within the androstane course containing a ketone and also a hydroxyl group at positions 3 and seventeen respectively. It is actually biosynthesized in several measures from cholesterol and is also converted within the liver to inactive metabolites.[eight] It exerts its motion as a result of binding to and activation of the androgen receptor.[eight] In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, into a lesser extent, the ovaries of females.

The bones as well as the brain are two vital tissues in humans in which the principal influence of testosterone is Through aromatization to estradiol. During the bones, estradiol accelerates ossification of cartilage into bone, bringing about closure of the epiphyses and conclusion of growth. From the central anxious system, testosterone is aromatized to estradiol.
