title: Plasma and testicular testosterone in experimental diabetic rats.
abstract: Testicular and plasma testosterone levels were found to be decreased markedly in streptozotocin diabetic rats compared with those of controls. Treatment with 6 units NPH insulin daily for one week almost normalized plasma testosterone levels parallel to the increase in body and liver weights in diabetic rats, while testosterone levels in testicles were not significantly changed. Plasma prolactin and LH levels were unchanged among control, diabetic and diabetic insulin-treated rats. Thus, testosterone reduction in the testis might play a role in diabetic impotence.
