Recent developments in hormonal assay have yielded biological methods of clinical importance in the early diagnosis and prognosis of teratoma testis. From reports of large series of patients suffering from this condition it would seem that the response of these tumors to radiation is accompanied by variations in the quantities of hormone excreted in the urine with such regularity as to render the quantitative determination of prolan A in the urine an accurate guide in prognosis and treatment.
