Hormones

Androstenedione

Precursor to testosterone and estrogens.

Androstenedione, a C19 steroid, is a crucial precursor hormone predominantly synthesized in the adrenal glands and gonads (ovaries or testes). It serves as an intermediate in the biochemical pathway that leads to the production of both androgens, such as testosterone, and estrogens, such as estrone. By contributing to the synthesis of these vital sex hormones, androstenedione plays a significant role in various physiological processes, including the development of secondary sexual characteristics and the regulation of reproductive functions in both males and females. Its measurement provides insights into the activity of these endocrine pathways.
