androstenedione

Androstenedione is an intermediate steroid horome produced in the adrenal glands and gonads (the testes and ovaries) as a precursor to the androgen, testosterone, and the estrogens, estrone and estradiol. It is, in part, produced in response to the release of ACTH by the anterior pituitary gland.
