title: Ultrafiltrable plasma testosterone and 5 alpha-dihydrotestosterone as measured across the human testes.
abstract: It has been confirmed that within the human plexus pampiniformis a venous-arterial transfer of testosterone (T) (5.95%) and of dihydrotestosterone (DHT) (16.58%) occurs. It could be established that in the testicular artery the percentage of ultrafiltrable DHT was significantly lower compared with the venous compartment. It is assumed that by this means a biological recycling of the active androgen DHT into the testis is achieved.
