Abstract
Summary
Thirty-two successful testicular homo transplants were recovered from 40 castrated male and female mice of the A strain bearing the intrasplenic transplants for a period ranging from 23 to 275 days. The testicular transplants showed the general histological features of cryptorchid testes, although spermatids and sperm heads were noted in one case after 243 days of transplantation. The present material gave no indication of tumor development in the intrasplenic testicular transplants. The experimental data suggested that the endogenous androgen produced by the intrasplenic testicular transplant was inactivated when passing through the hepatic portal system.
