Summary.

When [3H]testosterone was infused through the spermatic artery of anaesthetized dogs, [3H] testosterone and [3H]5α-dihydrotestosterone could be found both in the lymph and in the spermatic venous blood from the infused gonad. The concentration of radioactive testosterone and dihydrotestosterone per ml of testicular lymph was comparable to that per ml of spermatic venous blood. Because of the marked difference in flow rate, most of the androgens were, however, delivered from the testis through the spermatic vein.
