Androstenedione is a hormone produced naturally in the body by the adrenal glands, the ovaries (in women), and the testicles (in men). The body first manufactures DHEA , then turns DHEA into androstenedione, and finally transforms androstenedione into testosterone, the principal male sex hormone. Androstenedione is also transformed into estrogen.Androstenedione is widely used by athletes who believe that it can build muscle and increase strength. However, there is no evidence that it works. Furthermore, androstenedione supplements may cause positive urine tests for illegal steroid use, due to the common presence of a contaminant (19-norandrostenedione).The typical recommended dose of androstenedione is 100 mg 2 times daily with food.
Due to its secretion from a number of different glands and its often rapid conversion to other hormones, the control of androstenedione within the body is very complex. However, two key parts of the brain (the hypothalamus and pituitary gland) are known to be important in the control of androstenedione secretion from the testes, ovaries and adrenal cortex. The release of androstenedione by the adrenal cortex is thought to be related to the pituitary gland’s secretion of a specialised hormone, adrenocorticotropic hormone. Precisely how adrenocorticotropic hormone and other hormones control the adrenal gland’s production of androstenedione is, however, unclear. The testes and ovaries are stimulated to release androstenedione by luteinising hormone and follicle stimulating hormone. These are released from the anterior pituitary gland in response to a hormone signal from the hypothalamus.
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.
