To determine prospectively the effectiveness in clinical practice of a prediction model for high- order multiple pregnancies (HOMP) (triplets or more). Prospective study. University teaching hospital. Eight hundred forty- nine consecutive infertile patients undergoing a total of 1,542 treatment cycles. Gonadotropin ovarian stimulation or induction of ovulation without IVF Observed and predicted overall pregnancy rates and the incidence of HOMP. The use of the prediction model (implying cancellation of all cycles at high risk for HOMP) would result in an 8% (95% confidence interval, 6.8% - 9.2% ) reduction of overall pregnancy rate but also in a 285% (95% CI, 279% - 291% ) reduction of HOMP. By using our prediction model, it was possible to maintain a low risk of HOMP with a good pregnancy rate in patients receiving gonadotropin ovarian stimulation or induction of ovulation without IVF.
