Abstract

Seven unconjugated neutral steroids, including testosterone and some of its precursors and metabolites, were measured in the peripheral and spermatic venous blood males, employing specific radioimmunoassays after the fractionation of steroids on Lipidex-5000 (hydroxyalkoxypropyl Sephadex) microcolumns. Respective mean concentrations (ng/ml) and ranges of steroids estimated in peripheral and spermatic venous blood in all groups of patients were as follows: pregnenolone, 0.71 (0.29-2.39) and 10.97 (0.83-30.1); progesterone, 0.31 (0.02-0.57) and 10.17 (1.51-33.24); 17 alpha-hydroxyprogesterone, 1.04 (0.48-2.20) and 37.33 (1.68-141.00); androstenedione, 1.01 (0.26-2.65) and 11.87 (0.97-30.18); testosterone, 3.84 (0.63-10.64) and 255.1 (2.85-619.1); 5alpha-dihydrotestosterone, 0.19 (0.07-0.28) and 3.74 (0.04-9.71); androsterone, 0.27 (0.12-0.47) and 0.97 (0.20-2.15). Concentrations are similar to those estimated by mass spectrometry and protein binding assays, except for androsterone which has not previously been measured in this context. The low, but significant testicular secretion of both 5alpha-hydrotestosterone and androsterone suggests that these two steroids are testicular androgen metabolites, and that androgen metabolism in this tissue may be monitored by way of their measurement in spermatic vein blood.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
