title: Pregnancies and births achieved from in vitro matured oocytes retrieved from poor responders undergoing stimulation in in vitro fertilization cycles.
abstract: OBJECTIVE
  To describe pregnancies that resulted from in vitro matured oocytes derived from stimulated IVF cycles before cancellation owing to poor response of gonadotropins.
  
  
  METHODS
  Case report. University hospital.
  
  
  METHODS
  Eight patients who underwent in vitro maturation.Immature oocyte retrieval, in vitro maturation of immature oocytes, fertilization, and ET. Luteal support with progesterone and plvyeron was given.
  
  
  METHODS
  Pregnancy and live birth.
  
  
  RESULTS
  Three pregnancies (two live births and another ongoing) were achieved after immature oocyte retrieval, in vitro maturation, fertilization with ICSI, and ET.
  
  
  CONCLUSIONS
  Immature oocyte retrieval from poor responders during stimulation, followed by in vitro maturation, may be an alternative before the cycle is canceled.
