Androgen: A male sex hormone that promotes the development and maintenance of the male sex characteristics. The major androgen is testosterone.
Androstenedione is a naturally occurring androgenic steroid that is produced by the adrenal glands, ovaries, and testicles. Once released into the blood it is rapidly converted into testosterone, but there are also pathways through which androstenedione is converted into estrogen.or example the IOC, NCAA and NFL ban the use of androstenedione, whereas Major League Baseball, the National Basketball Association, and the National Hockey League do not. In the future look for tighter regulation of androstenedione. In the meantime avoid this stuff like the plague.
