Stimulation of testicular ornithine decarboxylase activity by arginine vasopressin.
Intratesticular injection with arginine vasopressin caused stimulation of ornithine decarboxylase activity in the testes of immature rats. The increase in ornithine decarboxylase activity in response to arginine vasopressin was dose and time dependent. Maximal stimulation of ornithine decarboxylase activity occurred at 2 h after injection with 0.1 micrograms of arginine vasopressin. It was observed that stimulation of ornithine decarboxylase activity occurred in seminiferous tubules and in Leydig cells of the testis in response to arginine vasopressin.
