    Androstenedione, or 4-androstenedione (abbreviated as A4 or Δ4-dione), also known as androst-4-ene-3,17-dione,is an endogenous weak androgen steroid hormone and Intermediate in the biosynthesis of testosterone from 

    dehydroepiandrosterone (DHEA) and of estrone. It is closely related to androstenediol (androst-5-ene-3β,17β-diol).

    Androstenedione is a precursor to testosterone and other androgens, as well as of estrogens like estrone, in the body. In addition to functioning as an endogenous prohormone, androstenedione also has weak androgenic activity in its own right.

    Androstenedione has been found to possess some estrogenic activity, similarly to other DHEA metabolites. However, in contrast to androstenediol, its affinity for the estrogen receptors is very low, with less than 0.01% of the affinity of estradiol for both the ERα and ERβ.

      Functions of Androstenedione:   

    A highly publicized study indicates that androstenedione may not live up to its hype. The study published in the June 2, 1999 issue of the Journal of the American Medical Association compared 300 mg with a dummy pill in 20 men ages 19 to 29 during an eight-week weightlifting program. Researchers found no difference in strength between the two groups of men.

    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.

       Applications of 4-AD:   

    1. Androstenedione is a steroid hormone. It is used to make medicine.

    2. Androstenedione is used to increase the production of the hormone testosterone to enhance athletic performance, increase energy, keep red blood cells healthy, enhance recovery and growth from exercise, and increase sexual desire and performance.
