title: Successful pregnancy and delivery after testicular sperm extraction despite an undetectable concentration of serum inhibin B in a patient with nonobstructive azoospermia.
abstract: OBJECTIVE
  To describe a successful pregnancy and delivery after testicular sperm extraction (TESE) despite an undetectable concentration of serum inhibin B in a man with nonobstructive azoospermia.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Obstetrics and gynecology and reproductive biology departments.
  
  
  METHODS
  A 31-year-old woman and a 32-year-old man with nonobstructive azoospermia and an undetectable inhibin B serum level.
  
  
  METHODS
  TESE, testicular spermatozoa cryopreservation, intracytoplasmic sperm injection (ICSI).
  
  
  METHODS
  Pregnancy and delivery.
  
  
  RESULTS
  Successful pregnancy and delivery of a normal healthy child following a third ICSI cycle with frozen-thawed spermatozoa extracted from the testis.
  
  
  CONCLUSIONS
  This case report shows that there is no minimal level of inhibin B below which TESE is always unsuccessful. The delivery of a normal healthy baby is strong evidence to perform TESE in these circumstances.
