  schema:description "Leydig cell tumour is the commonest testicular tumour that is not a germ cell tumour; it grows from the hormone-making cells between the seminiferous tubules. It often makes testosterone or oestrogen, causing early puberty in boys or breast growth in men, and about nine in ten are benign and cured by surgery; the malignant minority responds poorly to chemotherapy."@en ;
