Some of the pigs introduced into the Shibaura Abattoir, Tokyo, from Nagano Prefecture on July 17, 1969, presented many irregularly round nodules of miliary or egg size scattered on the surface of peritoneal organs, including diaphragm, liver, gallbladder, omentum, colon, prostate, and ureteral muscle. Histopathologically, these nodules were composed of tissue similar to the testicular one, but contained no spermatids. It was demonstrated that hormone had been secreted from them.The cause of formation of these nodules was studied and proved to be the transplantation of such free testicular tissue as appearing after the performance of non-sanguineous castration by the ball masher method of Miyazawa.
