title: Seminal plasma levels of testosterone and 5 alpha-dihydrotestosterone in azoospermic patients.
abstract: Testosterone (T) and 5 alpha-dihydrotestosterone (DHT) have been measured in seminal plasma of sixteen azoospermic patients with tubular damage (germinal cell arrest or Sertoli cell only syndrome) and five patients affected by azoospermia of obstructive origin. In both groups T values were not significantly different from controls, while DHT was significantly lower in patients affected by azoospermia of obstructive origin.
