title: [Reinsemination by intracytoplasmic sperm injection 24-hour after conventional in vitro fertilization failure].
abstract: OBJECTIVE
  To examine the efficacy of intracytoplasmic sperm injection (ICSI) for rescue of conventional in vitro fertilization (IVF) failure.
  
  
  METHODS
  From June 1997 to October 1998, 17 women with non-male factor infertility undergoing conventional ovarian hyper-stimulation protocol and IVF in our center, with fertilization failure were reinseminated by ICSI.
  
  
  RESULTS
  Intracytoplasmic sperm injection of 130 unfertilized mature oocytes resulted in degeneration in 25 oocytes, successful fertilization occurred in 100 (76.9%) of the survival oocytes, and embryo transfer were done in 18 cycles. Two viable pregnancies resulted.
  
  
  CONCLUSIONS
  If chromosome abnormalities of embryos arising from reinsemination were ignored, our results suggest that ICSI is a successful means of rescuing conventional IVF failure.
