title: [Diagnosis and treatment of bilateral testicular intratubular seminoma: a case report and review of literature].
abstract: OBJECTIVE
  To explore the diagnosis and treatment of testicular intratubular seminoma.
  
  
  METHODS
  One case of testicular intratubular seminoma was diagnosed with testicular biopsy. Epididymal sperm was aspirated and intracytoplasmic sperm injection ( ICSI) was performed. And local radiotherapy was conducted on the bilateral testes after fertilization.
  
  
  RESULTS
  The result of testicular biopsy revealed bilateral testicular intratubular seminoma. Large numbers of sperms were found in the epididymal aspirate. ICSI did not succeed for the first time. The second ICSI succeeded. The local radiotherapy by 60Co had been conducted on the bilateral testes, and testicular tumor didn't develop further.
  
  
  CONCLUSIONS
  Testicular intratubular seminoma is a type of intratubular germ cell neoplasia, with no clinical manifestations, and usually found in testicular biopsy. Earlier management promises better prognosis.
