The presenting features may be a palpable testicular mass or asymmetric testicular enlargement in some cases. The tumour may present as signs and symptoms relating to the presence of widespread metastases, without any palpable lump in the testis. The clinical features associated with metastasising<unk>  may include low back pain, dyspnoea, cough, haemoptysis, haematemesis and neurologic abnormalities. Males with pure<unk>  tend to have a normal amount of the protein alpha-fetoprotein in the fluid component of their blood. The finding of elevated amounts of alpha-fetoprotein is more suggestive of a mixed germ cell tumour, with the alpha-fetoprotein being released by the yolk sac tumour component.
