title: Acute renal failure may lead to reversible azoospermia.
abstract: OBJECTIVE
  To report a possible association between azoospermia and acute renal failure.
  
  
  METHODS
  A case report.
  
  
  METHODS
  An in vitro fertilization unit in an academic medical center.
  
  
  METHODS
  A patient with high-gonadotropin azoospermia and a history of acute obstructive renal failure because of bilateral renal calculi, who was referred for testicular sperm extraction.
  
  
  METHODS
  Deferral of the surgical procedure.
  
  
  METHODS
  Return of sperm into the patient's ejaculate.
  
  
  RESULTS
  Four months after normalization of his renal function tests, the sperm analysis showed reversal of the azoospermic state.
  
  
  CONCLUSIONS
  Azoospermic patients with recent history of acute renal failure would be followed up for several months after renal function normalization, awaiting reappearance of sperm in the ejaculate.
