title: Ovarian volume: a novel outcome predictor for assisted reproduction.
abstract: OBJECTIVE
  To determine the potential of ovarian volume as a predictor of assisted reproduction outcomes.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  University-based assisted reproduction program.
  
  
  METHODS
  One hundred eighty-eight women initiating their first cycle of assisted reproduction.
  
  
  METHODS
  None.
  
  
  METHODS
  Pretreatment transvaginal ultrasound ovarian measurements were compared with subsequent ovulation induction parameters (peak E2, numbers of oocytes, and embryos) and cycle outcome (cancellation and pregnancy).
  
  
  RESULTS
  Total ovarian volume and volume of the smallest ovary were significant variables predicting peak E2 and numbers of oocytes and embryos. Total ovarian volume was a predictor of cycle cancellation and volume of the smallest ovary a predictor of clinical pregnancy. Large ovarian volumes are associated with good assisted reproductive technology outcomes whereas small ovarian volumes are associated with poor outcomes.
  
  
  CONCLUSIONS
  Beyond maternal age, total ovarian volume, and volume of the smallest ovary are significant predictors of the success of assisted reproductive techniques.
