Male: 300 -1,000 ng/dL. Female: 15 - 70 ng/dL. Testosterone is a steroid hormone (androgen) produced by special endocrine tissue (the Leydig cells) in the male testicles. It is also produced by the adrenal glands in both males and females and, in small amounts, by the ovaries in females. This test measures the level of testosterone in the blood. ................
