Calculate the probability of a spontaneous ongoing pregnancy within 1 year (leading to live birth).

Calculate the probability of a spontaneous ongoing pregnancy within 1 year
(leading to live birth).

This probability is not reliable in case of :

-Women with ovulation dysorders
-Men with severe male factor (Total motile sperm count = volume x concentration x % motility < 3 milion)
-Women with 2-sided tubal pathology.

This model has been validated between 2002-2004 in 38 hospitals in the Netherlands by Van der Steeg et al. In the Colaborative Effort of Clinical Evaluation in Reproductive Medicine (CECERM). The models showed to predict accurately.
