What is Androstenedione?
Androstenedione is a steroid hormone. Our body needs it to produce two other vital hormones, testosterone and estrogen. Androstenedione is sometimes ingested to increase the production of testosterone for the purpose of gaining athletic advantage.
Why test Androstenedione?
We wish to see levels within normal ranges for age and gender. As this hormone is a precursor hormone, “normal” levels will indicate subsequent consistent androgens hormone production e.g. testosterone, is taking place.
What Will the Results reveal?
An elevated level of androstenedione indicates increased adrenal, ovarian or testicular production. Small fluctuations in concentration are usually normal. An increased level may indicate an adrenal tumor, adrenal cancer, adrenal hyperplasia, or congenital adrenal hyperplasia (CAH). An increased level is not diagnostic of a specific condition; it usually indicates the need for further testing to pinpoint the cause.
Low androstenedione in turn affects dependant androgen hormone productivity as this is a major precursor hormone. It is also associated with adrenal gland dysfunction, adrenal insufficiency, and ovarian or testicular failure.
