title: [Intracytoplasmic morphologically selected sperm injection of testicular sperm: clinical outcome in azoospermia patients].
abstract: OBJECTIVE
  To assess whether intracytoplasmic morphologically selected sperm injection (IMSI) of testicular sperm improves the clinical outcome in patients with azoospermia.
  
  
  METHODS
  We performed conventional intracytoplasmic sperm injection (ICSI) for 66 patients diagnosed with azoospermia and IMSI for another 39 using testicular sperm selected at high magnification ( x 6000), and comparatively analyzed the clinical outcomes of the two techniques.
  
  
  RESULTS
  There were no statistically significant differences between conventional ICSI and IMSI in the rates of pregnancy (51.52% vs. 56.41%) and implantation (30.67% vs. 35.29%), although the rate of early abortion was lower in the IMSI than in the ICSI group (4.50% vs. 11.76%).
  
  
  CONCLUSIONS
  IMSI of testicular sperm may effect a lower rate of early abortion than conventional ICSI in patients with azoospermia.
