title: [Intracytoplasmic sperm injection does not improve the clinical outcomes of the males with 100% teratozoospermia].
abstract: OBJECTIVE
  To investigate whether intracytoplasmic sperm injection (ICSI) can improve the clinical outcomes of the male patients with 100% teratozoospermia.
  
  
  METHODS
  We retrospectively analyzed the clinical data of 152 couples undergoing in vitro fertilization-embryo transfer (IVF-ET), including 75 cycles of IVF and 77 cycles of ICSI. We compared the rates of normal fertilization, high-quality embryos, transferrable embryos, implantation, clinical pregnancy, and abortion between the two groups.
  
  
  RESULTS
  In the 100% teratozoospermia patients the number of transferrable embryos was significantly lower in the IVF than in the ICSI group (78.91% vs 84.92%, P < 0.05), while the rates of normal fertilization and implantation were higher in the former than in the latter (60.26% vs 57.87% and 48.00% vs 39.55%, both P > 0.05). There were no statistically significant differences between the two groups in the female age, Gn days, Gn dose, BMI, infertility duration, endometrial thickness, and basal serum FSH and E2.
  
  
  CONCLUSIONS
  ICSI cannot improve the clinical outcomes of the male patients with 100% teratozoospermia.
