title: Successful pregnancies after using immotile spermatozoa from ejaculate, epididymis and testis.
abstract: OBJECTIVE
  To assess the efficacy of intracytoplasmic sperm injection (ICSI) in term of pregnancy rate with immotile spermatozoa from ejaculate, epididymis and testis.
  
  
  METHODS
  A retrospective study was conducted between January 1998 and March 2001. We performed intracytoplasmic sperm injection with immotile spermatozoa, in 160 couples during 172 cycles.
  
  
  RESULTS
  The birth rate per cycle was 38.4% in immotile spermatozoa from ejaculate, 35.4% from testis and 38.7% from epididymis.
  
  
  CONCLUSIONS
  This retrospective analysis shows that immotile spermatozoa retrieved from epididymis or testicle gives similar fertilization and pregnancies rates as immotile spermatozoa from ejaculate.
