Fig. 4. Predicted cumulative ongoing pregnancy rates for several conditions.

(a) Predicted probabilities using female age as predictor. Taking a 15% cumulative pregnancy rate in three cycles as minimal level of success, such a poor prospect cannot be predicted by age for any single woman.

(b) Predicted probabilities using female age, poor response, and poor response type as predictors. Taking a 10% cumulative pregnancy rate in cycles 2 and 3 as minimum success level, only in cycle 1 poor responders, who were expected based on the ovarian reserve test combination (FSH, antral follicle count, inhibin B), can such poor prognosis situations be identified.

PR = cycle 1 poor responder; NR = cycle 1 normal responder; Exp PR = cycle 1 poor responder with abnormal ovarian reserve testing; Unexp PR = cycle 1 poor responder with normal ovarian reserve testing.
