title: In vitro fertilization in patients with ovarian endometrioma.
abstract: OBJECTIVE
  To assess the influence of ovarian endometrioma during IVF.
  
  
  METHODS
  Patients were submitted to cystectomy by the laparoscopic route for exeresis of ovarian endometrioma. Group I (n = 28) consisted of patients without ovarian endometrioma and group II (n = 14) consisted of patients with recurrence of ovarian endometrioma during IVF.
  
  
  RESULTS
  Fertilization and cleavage rates were higher in group I and the pregnancy rate per transfer was similar in the two groups.
  
  
  CONCLUSIONS
  The presence of endometrioma during IVF causes a worsening of oocyte fertilization and embryo cleavage but does not affect the pregnancy rate per transfer.
