Differential Diagnosis of Organic and Functional Impotence by the Use of ¹³¹I-Human Serum Albumin

Abstract

Seven and nine cases of organic and mental impotence, respectively, were examined for changes in circulating blood in the penis after the administration of ¹³¹I-human serum albumin. As a result, there was a remarkable difference in the amount of circulating blood in the penis between the two groups. This method of examination using an isotope was applied to patients in a painless testing situation. It was also simple enough to be performed at any clinic equipped with a renogram apparatus. These results require verification by further studies on a larger number of patients.
