title: Intracytoplasmic sperm injection outcomes of obstructive and nonobstructive azoospermic men.
abstract: OBJECTIVE
  We aimed to compare the outcomes of intracytoplasmic sperm injection (ICSI) cycles in obstructive and nonobstructive azoospermic men.
  
  
  METHODS
  In this retrospective study, we searched the first ICSI cycle parameters of 211 azoospermic men. Our main outcomes were the average fertilization rate, implantation rate, pregnancy and miscarriage rates.
  
  
  RESULTS
  The results of this study showed that although the males with obstructive azoospermia had better fertilization and biochemical pregnancy rates than the ones with nonobstructive azoospermia, clinical pregnancy and miscarriage rates among the groups were similar.
  
  
  CONCLUSIONS
  ICSI overcomes the obstacles related to the sperm in its function as a carrier but it cannot alter the message carried by the male gamete.
