He spent twelve years in studying the chemophysiology of the internal secretions of the embryo and asserts that he has isolated substances which, when injected into aging individuals, result in a definite regeneration of the affected tissues. This form of therapy Ischlondsky designates as "incretion treatment" or as "therapia protoformativa multispecifica." More than 400 cases were observed. Ischlondsky divides these into (a) senile persons and (b) young individuals suffering from disease. He condemns "substitution therapy" by hormones as practiced today. It should be replaced, he insists, by his "only true, sensible method."
