title: Return of fertility after autologous stem cell transplantation.
abstract: OBJECTIVE
  To study cases where bone marrow transplantation (BMT) or peripheral blood stem cell transplantation (PBSCT)-induced menopause was entirely reversed.
  
  
  METHODS
  Retrospective analysis.
  
  
  METHODS
  An inpatient BMT unit and an ambulatory fertility center in a university hospital.
  
  
  METHODS
  Two patients with Hodgkin's disease and two with advanced breast carcinoma requiring stem cell transplantation.
  
  
  METHODS
  Estrogen treatment, monitoring of follicle-stimulating hormone (FSH) and estradiol (E(2)) levels, and, ultimately, monitoring of pregnancy.
  
  
  METHODS
  Pregnancy.
  
  
  RESULTS
  All four patients established pregnancies, but two of them elected to terminate due to the use of tamoxifen early in pregnancy.
  
  
  CONCLUSIONS
  Menopausal changes resulting from BMT may spontaneously reverse, with reestablishment of normal hormonal function and viable pregnancies.
