Testosterone, C19H28O2, (4-Androsten-17β-ol-3-one) is a steroid hormone from the androgen group and is found in mammals, reptiles, birds, and other vertebrates. In mammals, testosterone is primarily secreted in the testes of males and the ovaries of females, although small amounts are also secreted by the adrenal glands. It is the principal male sex hormone and an anabolic steroid. In the absence of testosterone stimulation, spermatogenesis does not proceed beyond the meiosis stage. Testosterone plays a significant role in glucose homeostasis and lipid metabolism. Testosterone is observed in most vertebrates. Fish make a slightly different form called 11-ketotestosterone. Its counterpart in insects is ecdysone. These ubiquitous steroids suggest that sex hormones have an ancient evolutionary history.
