Androgens are male sex hormones:
testosterone, androsterone and androstenedione. Androgens are steroid hormones of cyclopentaneperhydrophenanthrene, whose main function is to stimulate the development of male sexual characteristics. Androgens, basically testosterone, are secreted by the testes, but also by the ovaries in women (androstenedione) and by the adrenal cortex of the adrenal glands (mainly dihydroepiandrosterone). In man only 10% of androgens have an adrenal origin. All natural androgens come from androstane steroids (a tetracyclic hydrocarbon nucleus of 19 carbon atoms). It is also the precursor of all estrogens, the female sex hormones.
Androsterone is an intermediate in the synthesis of androgens in humans:
Androsterone is a substance produced naturally by man and is not harmful to the human body, but when taken synthetically, it is metabolized in the body producing steroids.
Androstenedione or androstenedione (also known as 4-androstenedione) is a 19-carbon steroid hormone produced in the adrenal glands and in the gonads (ovaries in women and testes in man) as an intermediary in the biochemical process that produces androgen testosterone and the estrogens estrone and estradiol.
Testosterone is a sexual steroid hormone of the androgen group and is found in mammals, reptils, birds and other vertebrates and some invertebrates such as insects with some differences, called ecdysone. In mammals, testosterone is produced mainly in the testes of males and in the ovaries of females, and the adrenal glands also secrete small amounts. It is the main male sex hormone and it is also an anabolic steroid.
Testosterone in males:
Testosterone plays a key role in the development of male reproductive tissues such as the testes and the prostate, and also in the promotion of secondary sexual characteristics such as, for example, the increase of muscle and bone mass and hair growth. bodily. In addition, it is essential for health and well-being, as well as for the prevention of osteoporosis. On average, the concentration of testosterone in the blood plasma in a male human adult is ten times greater than the concentration in the plasma of female human adults, but as the metabolic consumption of testosterone in men is higher, the daily production is approximately 20 times greater in men. So too, women are more sensitive to the hormone.
