Subnormal tissue 3 alpha-androstanediol and androsterone in prostatic hyperplasia.
We investigated the role of 3 alpha-androstanediol (3 alpha-diol) in the development of benign prostatic hyperplasia (BPH) and the apparent equilibrium of enzymes which metabolize it in normal and hyperplastic prostatic tissue of humans.
We determined the endogenous concentrations of 3 alpha-diol, androsterone, its 3 alpha-17-keto metabolite or precursor, and 5 alpha-dihydrotestosterone (DHT), its 3-keto,17 beta-hydroxy product of precursor, by RIA after extraction and paper chromatography of the androgens from normal and hyperplastic prostate glands.

 Metabolism of Orally Administered Androstenedione in Young Men, The World Health Network - Anti-Aging and Longevity
In the 100 mg group, mean d 1 and 7 excretion rates for testosterone, androsterone, etiocholanolone, and dihydrotestosterone were 47 ± 11, 3,836 ± 458, 4,306 ± 458, and 1.6 ± 0.2 µg/h, respectively.
In the 300 mg group, mean d 1 and 7 excretion rates for testosterone, androsterone, etiocholanolone, and dihydrotestosterone were 115 ± 39, 8,142 ± 1,362, 10,070 ± 1,999, and 7.7 ± 1.5 µg/h, respectively.
We conclude that the administration of both 100 and 300 mg androstenedione increases the excretion rates of conjugated testosterone, androsterone, etiocholanolone, and dihydrotestosterone and the serum levels of testosterone glucuronide in men.
