[The importance of chorionic gonadotropin excretion in diagnosis and therapy of testicular tumours (author's transl)].

Systematic investigations of the chorionic gonadotropin excretion were performed in 79 patients with testicular tumours. The influence of the hormonal activity in diagnosis and prognosis of metastatic testicular tumours was investigated. It was discovered, that the part of hormonal active testicular tumours is relatively small and that the evidence of the chorionic gonadotropin excretion is only possible in a few cases before the clinical and radiological evidence of metastases. The hormonal activity of testicular tumours is without influence on the survival time of tumour carriers.
