title: Efficacy of in vitro fertilization after chemotherapy.
abstract: OBJECTIVE
  To evaluate if in vitro fertilization (IVF) with embryo cryopreservation can be proposed to patients immediately after one or two regimens of chemotherapy.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Academic research center and IVF unit.
  
  
  METHODS
  Eleven young patients diagnosed with cancer between September 1999 and April 2003 who wanted to preserve their fertility via IVF.
  
  
  METHODS
  Stimulation and IVF before or soon after chemotherapy treatment.
  
  
  METHODS
  The number and quality of embryos obtained after stimulation in cancer patients undergoing IVF before or soon after chemotherapeutic treatment.
  
  
  RESULTS
  Four patients underwent IVF in the interval between two regimens of chemotherapy. Two of them had no follicular development; one underwent follicular puncture but no oocytes were retrieved; and, in one, six oocytes were harvested but only one good quality embryo was obtained. In the seven patients who underwent IVF before starting chemotherapy, between 4 and 11 embryos were obtained per patient, the majority being good quality embryos.
  
  
  CONCLUSIONS
  Because the efficacy of IVF is dramatically reduced after even one round of chemotherapy, IVF should be performed before chemotherapy. For those who require immediate chemotherapy, ovarian tissue cryopreservation and/or oocyte cryopreservation could be used before treatment.
