title: Effect of a baseline ovarian cyst on the outcome of in vitro fertilization-embryo transfer.
abstract: OBJECTIVE
  To determine the significance of prestimulation ovarian cysts on the response to controlled ovarian hyperstimulation and the outcome of IVF.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  In vitro fertilization unit in an academic center.
  
  
  METHODS
  One hundred thirty-seven patients undergoing IVF.
  
  
  METHODS
  The outcome of 71 patients who had an ovarian cyst of >10 mm detected at ultrasound examination performed on day 3 was compared with that of 66 patients who underwent a similar protocol and did not have an ovarian cyst.
  
  
  METHODS
  Parameters evaluated were the E2 level on the day of hCG administration, the number of follicles, the number of oocytes retrieved, the number of embryos transferred, and the pregnancy rate.
  
  
  RESULTS
  The E2 level on the day of hCG administration and the number of mature oocytes retrieved were lower in the group with a baseline cyst. The pregnancy rate also was significantly lower in the group with a cyst (24% versus 41%). The presence of a baseline ovarian cyst decreases the odds of pregnancy 0.37-fold (95% confidence interval, 0.16-0.87).
  
  
  CONCLUSIONS
  A baseline ovarian cyst on cycle day 3 was associated with a poorer outcome after IVF-ET.
