Androstenedione. Androstenedione is a 19-carbon steroid hormone produced in the adrenal glands and the gonads as an intermediate step in the biochemical pathway that produces the androgen testosterone and the estrogens estrone and estradiol.
Androstenedione is POSSIBLY UNSAFE for most people when taken by mouth. Some side effects experienced by men include reduced sperm production, shrunken testicles, painful or prolonged erections, breast development, behavioral changes, heart disease, and others.here is some concern that the strength and purity of androstenedione products may not match the product labeling.

Pregnancy and breast-feeding: Androstenedione is LIKELY UNSAFE to use during pregnancy. It might bring on labor and cause a miscarriage. Androstenedione may refer to: 1  δ4-Androstenedione, a weak androgen and an intermediate in the biosynthesis of testosterone from DHEA. 2  δ5-Androstenedione, a prodrug of testosterone and hence an androgen/anabolic steroid.3  δ1-Androstenedione, a prodrug of δ 1 -testosterone and hence an androgen/anabolic steroid. Androstenedione may be ordered, along with or following other hormone tests, whenever excess (or, more rarely, deficient) androgen production is suspected and/or when a doctor wants to evaluate a person's adrenal gland, ovarian, or testicular function.ndrostenedione concentrations increase in boys undergoing puberty, for about two years prior to significant increases in testosterone. Androstenedione levels are not usually used to monitor this process. Adrenal androstenedione is the major source of androgens for postmenopausal women. Likely Ineffective for: 1  Enhancing athletic performance. 2  Taking androstenedione by mouth in doses of 100-300 mg per day does not significantly increase muscle strength, muscle size, or lean body mass when used for 2-3 months in connection with weight training.here is some concern that the strength and purity of androstenedione products may not match the product labeling.

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. An androstenedione level may be used to: 1  Evaluate adrenal gland function and to distinguish between androgen-secreting conditions that are caused by the adrenal glands from those that originate in the ovaries or testicles, if results of DHEAS and testosterone testing are abnormal. Androstenedione concentrations increase in boys undergoing puberty, for about two years prior to significant increases in testosterone. Androstenedione levels are not usually used to monitor this process. Adrenal androstenedione is the major source of androgens for postmenopausal women.
