title: The relationship between plasma levels of gonadotropins, androgens, and prolactin in azoospermic men with their testicular spermatogenic pattern.
abstract: OBJECTIVE
  To assess the relationship between plasma levels of gonadotropins, androgens, and PRL with testicular spermatogenic pattern.
  
  
  METHODS
  Patient series.
  
  
  METHODS
  University affiliated medical center.
  
  
  METHODS
  One hundred twenty azoospermic infertile men.
  
  
  METHODS
  Testicular fine needle aspirations and determination of plasma levels of FSH, LH, T, free T, and PRL.
  
  
  METHODS
  Gonadotropins, androgens, and PRL plasma levels as a diagnostic criterion of testicular spermatogenic patterns.
  
  
  RESULTS
  No statistically significant differences were detected in plasma levels of LH, androgens, and PRL among patients with Sertoli cell only, spermatogenic arrest, or full spermatogenesis. Elevated plasma levels of FSH threefold above the upper normal limit preclude, with a probability of 95%, the existence of full testicular spermatogenesis, but are not valid for the diagnosis of either Sertoli cell only syndrome or spermatogenic arrest.
  
  
  CONCLUSIONS
  Luteinizing hormone, androgens, and PRL plasma levels are of no diagnostic value in predicting any specific spermatogenic pattern, and plasma FSH levels can not be used for diagnosing Sertoli cell only syndrome.
