Testo-ster-one precursor and metabolite with androgenic activity. Controlled substance (anabolic steroid); Simplified hormone drugs, from the testis or urine extracted with the role of a male hormone steroids, norethisterone, testosterone propionate in the middle body, is widely used in small rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious inflammation.
4-Androstenedione can be synthesized in one of two ways. The primary pathway involves conversion of 17-hydroxypregnenolone to dehydroepiandrosterone by way of 17,20-lyase, with subsequent conversion of dehydroepiandrosterone to 4-Androstenedione via the enzyme 3-β-hydroxysteroid dehydrogenase. The secondary pathway involves conversion of 17-hydroxyprogesterone, most often a precursor to cortisol, to 4-androstenedione directly by way of 17,20-lyase. Thus, 17,20-lyase is required for the synthesis of 4-androstenedione, whether immediately or one step removed.
The production of adrenal 4-Androstenedione is governed by ACTH, whereas production of gonadal 4-Androstenedione is under control by gonadotropins. In premenopausal women, the adrenal glands and ovaries each produce about half of the total 4-androstenedione(about 3 mg/day). After menopause, 4-androstenedione production is about halved, due primarily to the reduction of the steroid secreted by the ovary. Nevertheless, 4-androstenedione is the principal steroid produced by the postmenopausal.
Androstenedione is described as a ‘pro-hormone’ because it has few effects itself. Instead, it is important because of the ability of different parts of the body to convert it into the hormones, testosterone and oestrogen, which exert many effects on the body.
In females, the outer part of the adrenal glands (known as the cortex) and the ovaries release androstenedione into the bloodstream where it is converted to provide around half of all testosterone and almost all of the body’s oestrone, a form of oestrogen. Although the testes produce large amounts of androstenedione in males, they secrete little of this into the blood and, instead, rapidly convert it into testosterone within the testes. The adrenal glands also produce androstenedione in men, but this contribution is swamped by the testes’ overwhelming production of the other androgenic hormone, testosterone.
