title: [Outcomes of in vitro fertilization-embryo transfer and intracytoplasmic sperm injection for non-male infertility patients with a low number of oocytes retrieved].
abstract: OBJECTIVE
  To compare the outcomes of in vitro fertilization-embryo transfer (IVF) and intracytoplasmic sperm injection (ICSI) in non-male infertility patients with a low number of oocytes retrieved and provide evidences for defining the indications of ICSI.
  
  
  METHODS
  A retrospective analysis was conducted among 220 non-male infertility patients with a low number of oocyte retrieved(≤5) including 151 receiving IVF and 69 undergoing ICSI. The baseline characteristics, ovary response index, fertilization results, embryo quality and clinical outcomes were compared between the 2 groups.
  
  
  RESULTS
  Although the fertilization rates, normal fertilization rates, complete fertilization failure rates, cleavage rates, good embryo rates, implantation rates and clinical pregnancy rates showed no significant differences between the 2 groups, the complete fertilization failure rates tended to decrease and the other indices tended to increase in IVF group.
  
  
  CONCLUSIONS
  ICSI can not improve the fertilization results, embryonic development potential or clinical outcomes in non-male infertility patients with a low number of oocytes retrieved, and is therefore not recommended for these patients.
