title: Plasma and semen androgens in normospermic and dysspermic subjects.
abstract: The seminal and plasmatic concentrations have been examined of testosterone, 5 alpha-dihydrotestosterone, and delta 4-androstenedione in normospermic and dysspermic subjects. The results obtained did not provide evidence of significant differences of androgen levels in fertile, hypofertile and sterile men.
