II. Epidemiology

  1. Androstenedione banned by IOC, NCAA, NFL
  2. DHEA banned by IOC

III. Sources

  1. Androgen synthesized by gonads and Adrenal Gland
    1. Natural intermediaries in endogenous testosterone synthesis from Cholesterol
  2. Used by athletes as performance enhancer
    1. Available in Europe as nasal preparation
    2. Available in U.S. as oral tablet

  1. Sustained increase in serum Estrogen
  2. Sustained increase in serum Luteinizing hormone
  3. Decreased HDL Cholesterol
  4. Priapism has occurred in case reports

Definition (NCI) A potent androgenic prohormone that is a direct precursor of testosterone and used as a supplement to increase plasma testosterone levels and muscle anabolism. (NCI)
Definition (NCI) A steroid hormone synthesized by the adrenal glands and the gonads from either 17-alpha-hydroxyprogesterone or dehydroepiandrosterone and is a precursor of testosterone.
Definition (MSH) A delta-4 C19 steroid that is produced not only in the TESTIS, but also in the OVARY and the ADRENAL CORTEX. Depending on the tissue type, androstenedione can serve as a precursor to TESTOSTERONE as well as ESTRONE and ESTRADIOL.
Definition (CSP) delta-4 C19 steroid that is produced in the testes, ovaries and adrenal cortex and can serve as a precursor to testosterone as well as estrone and estradiol.

Definition (NCI) A synthetic form of dehydroepiandrosterone with potential chemopreventive activity. Produced endogenously, dehydroepiandrosterone (DHEA) is an intermediate in the conversion of cholesterol to androgens and estrogens. Although the mechanisms of action of exogenously administered DHEA have not been fully illuminated, they may result in both direct and indirect physiologic effects. Direct effects include GABA-a receptor complex and NMDA receptor modulation, and enhanced pancreatic beta cell insulin secretion and antiglucocorticoid activities. (NCI04)
Definition (MSH) A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.
