Test/Profile NameAndrostenedione, Serum
Androstenedione is produced by the ovaries in women, the testicles in men, and by the adrenal glands in both. An excess level of androstenedione and other androgens can cause children to have sex organs that are not clearly male or female (ambiguous external genitalia), excess body hair (hirsutism), and abnormal menstrual periods (e.g. amoenorrhoea) in girls and precocious (early) puberty in girls and boys. Adrenal tumors, Adrenocorticotrophic Hormone (ACTH) producing tumors, and adrenal hyperplasia can lead to the overproduction of androstenedione. Women with Polycystic ovarian syndrome may have higher levels of androstenedione as well.
The level of androstenedione in the blood will vary during the day in a "diurnal pattern," and it will vary during a woman's menstrual cycle.
